Monday, December 6, 2010 ---The Edwards' Family made an announcement that I found personally disturbing. The wife of the former presidential candidate has decided to cease treatment for her cancer. Instead, she has opted to rest at home with friends and family. Also mentioned, she was comfortable and experiencing no pain. At that, the doctrine of double effect immediately came to mind.
The doctrine of double effect is used to justify the case where a doctor administers drugs to relieve extreme pain fully aware that this may hasten the patients' death.
Having done some research on euthanasia, the doctrine of double effect has become particularly fascinating to me. This principle closely resembles euthanasia also otherwise known as "mercy killing" with only one single detail differentiating the two: Intent.
Intent abolishes any doctor of any wrong doing which can be considered euthanasia---- or worst, murder. Apparently, one single word can determine the difference between being kind or being "Kevorkian", of being morally wrong or of being a Samaritan.
Elizabeth Edwards, estranged wife of John Edwards and mother of four, had succumbed to breast cancer the next day---Tuesday December 7, 2010.

Animal Research
PETA is one well known animal rights organization committed to protect animals. Indeed, they are so popular they have become a household name. Many celebrities have become supporters of their campaign. Even to the point of posing naked in photographs to demonstrate their repulsion to animal exploitation. Yet, animals have always been used to benefit human kind. In fact, it is one of the very reasons we have survived as a species. We consume meat for food, put on fur for warmth, and use animal strength for labor. We even extract their hormones to treat many human diseases. Is the use of animals for research and experimental purposes any different?
Animal rights organizations maintain that the use of animal in research is unnecessary, primitive, and outdated. For instance, PETA (2010) claims that products get pumped into animal’s stomachs, rubbed into their skin, and squirted into their eyes for apparently no good reason. Instead, they cite computer models and cell structures as better alternatives (para. 3). Although our survival is no longer dependent on animals for food, warmth, or labor, the use of animals in research and experimentations is something that we cannot live without. We are a species plagued with many mental, behavioral, and medical problems. It is a fact that animal research has aided in the discoveries of many treatments including: Parkinson’s disease, schizophrenia, manic-depressive illness, obesity, drug addictions, depression, and many more disorders (Carlson, 2005, p. 19). The fact remains that these discoveries can only be made through biological research. Complex behavior and internal processes for one cannot be studied using computer models and cell structures as they cannot reflect the on goings within the context of a whole organism (Canadian Council on Animal care, 2010). They are simply no substitute. Without the use of animal research, we are unable to make progress in understanding and treating human diseases.
Supporters of animal rights argue that the use of animal research is inhuman and cruel. This is basically a misconception. The Institutional Animal Care and Use Committee (IACUC) is a governing body that reviews all research involving animals. Its job is to make sure that the use of animals is justified by the benefits of the study. It also makes sure that any pain and suffering that might occur are minimized (American Psychological Associated, 2010, para. 1). The IACUC inspects project and facility that uses animals, reevaluates the overall animal care and use program, and helps develop and deliver training and educational programs to the research community and the public on animal care and use (Carlson, 2005, p. 18). In addition to this, researchers are required to consider the implementation of the so called, “Three R’s” of research design. The Three Rs stand for Replacement (using non-animal technique such as computer modeling and cell cultures when possible), Reduction (reducing amount of animals) and Refinement (minimizing animal suffering and treating them humanely) (Canadian Council on Animal care, 2010).
Animal activists claim that animal research is unreliable and even dangerous. They further argue that there is a physiological difference between humans and other animals that prevents the results from being relevant to humans. However, one is only to look at the many medical discoveries that have come through animal testing to see that this is not the case. The discovery of insulin, vaccines and antibiotics, open heart surgery techniques, organ transplants, in-vitro fertilization, HIV drugs, hormone replacement therapy, organ rejection, and many other came about because of animal research (Singh, 2009). It is true that there is a difference between the physiology of animals and that of humans but if you really think about it, it is also true about one human individual to another. The fact is, the physiology of humans and animals are similar enough to yield the significant discoveries and knowledge we are all benefiting from today.
There is always going to be those who oppose animal research. Yet, history has proven its effectiveness and usefulness. All individuals have, in one form or another, benefited from its findings. The reality is animal research is important and indispensible

More on Pheromones
Pheromones in Humans: Research and Studies
Lately, many researchers are interested in discovering pheromones in humans. Many are convinced that humans also emit pheromones that govern behavior (Carlson, 2005, p. 272). One study conducted by Russell, Switz, and Thompson (1980) collected sweat from the armpits of one female donor, mixed with alcohol, and swabbed under the noses of other participants. The results showed that the rest of the female participants’ menstrual cycle gradually synchronized with the female sweat donor of which the sweat sample was taken from (Carlson, 2005, p. 273).
Another similar study conducted by McClintock (1971) discovered an occurrence similar to that of the Whitten effect found in mice. She found women with close relationships and who spend many hours together tended to have synchronized cycles. Also, it was discovered that women who spent time with men tended to have shorter cycles. Those who spent less time with the opposite sex tended to have longer cycles (Carlson, 2005, p. 273). McClintock later teamed up with another researcher by the name of Stern and elaborated on this experiment. Here, they had nine women donate sweat from their underarm pits for 8 hours a day. Twenty women then received the combination of sweat and isopropyl alcohol. This mixture was dabbed under their noses. The results found that the receiving women’s cycle either sped up or slowed down. Specifically, women who received the pheromone during pre-ovulation had shorter monthly cycles by approximately two days. The women whose ovulations were occurring during the experiment had delayed cycles as much as one day and a half. A controlled group was also utilized on this study. This control group did not receive any pheromones. They had no changes in their cycle. It was also noted in this study that nasal congestion in participants hampered the effects of the pheromone (Seppa, 1998).
Pheromone Physiology
All three experiments utilize the olfactory organ in the detection of pheromones. However, contrary to what one would assume, the primary olfactory system is not responsible for pheromone stimulus processing. Instead, processing lies in an organ called the vomeronasal organ (VNO). The vomeronasal organ is a group of sensory receptors at the base of a duct leading into the nasal passages (Carlson, 2005, 270). . This organ is sensitive to “nonvolatile compounds found in urine or other substances” (Carlson, 2005, 272). It is found in most mammals with the exception of dolphins and whales. In humans, the presence of this organ is a controversial issue. There are scientists, however, that believe that the human vemeronasal organ is located near the bottom of the septal wall that divides the nose (Woronczuk, Medwid, Neumann, and Eshelman, 1999). This theory was tested by inserting a specially designed electrode into the VNO. When inserted into the olfactory cleft and exposed to pheromones, no changes were found. Yet, when placed in the VNO, neurons were recorded to be responding. It should also be noted that hormone levels in the blood also changed. It is believed that the VNO sends information to the brain’s hypothalamus which is responsible for bodily functions such as mating. It is also possible that the VNO communicates with the limbic system---the part of the brain responsible for emotional responses (Woronczuk et al., 1999).
The presence of the vemeronasal organ in humans would explain why nasal congestion hampered the effects of pheromones in the McClintock and Stern experiment
Perhaps pheromones can be better related and illustrated through the occurrence related to hysterectomy. Many women who have undergone this surgery report lack of sexual urges following the procedure. In an article by Michael D. Lemonick (2004, February), Lemonick features a woman by the name of Roslyn Washington. Ms. Washington claims that the hysterectomy procedure left her with side effects she wasn’t prepared for. Among these were a decrease in sexual activity, lack of sexual desire, and failure to become stimulated from glances, looks, and touches from the opposite sex. When Ms. Washington opted to receive transdermal testosterone, she was once again able to feel “stimulated” (Lemonick, 2004). When the testosterone treatment was stopped, her desire began to once again decrease. This perhaps indicates that pheromones are responsible for sexual desire and is necessary to trigger sexual responses.
Evolutionary Perspective
It seems that pheromones related to sexual behavior is tied closely to attractiveness and mate selection. It has been suggested that the scent of the human body is a signal of “phenotypic and genetic quality” (Thornhill & Gangestad, 1999). According to an article by Thronhill and Gangestad (1999, March) women who were at their higher period of fertility during ovulation found that the scents of men who have greater body bilateral symmetry more attractive. On the other hand, women in low fertility phases or those who are on hormone based contraceptive do not show this preference. Other studies found that men did not prefer the scent of symmetrical women. These perhaps suggest that women have a more evolved preference to mate and reproduce with men who posses good genes.
It is proposed that symmetry equates good and healthy genes which in turn produce offspring who are not only healthy and developmentally sound but one that can survive into adulthood (Carey, 2006). Evolutionary theorists would probably tie this in with the parental investment theory. This theory suggests that women are pickier in mate selection due to the fact that their minimum investment in childbearing involves 9 months plus the physical traumatic experience of childbirth. It can be said that women value sires with good genes because they seek to minimize the number of their offspring because their investment is so much greater (Boyd & Bee, 2006, p. 90). In contrast, this theory proposes that men value availability. They are less selective on their partners because their minimum investment in parenting only required a single act of sexual intercourse. It can also be pointed out that “men seek to maximize the likelihood of the survival species by maximizing the number of their offspring” (Boyd & Bee, 2006, 90). Thus, this would explain why men did not prefer the scent of symmetrical women in the experiment conducted by Thronhill and Gangestad.
Genetic Standpoint
Researchers have been found that women preferred male odors belonging to men who were genetically different from their own. Swiss zoologist, Claus Wedekind, conducted an experiment using 49 women and 44 men with a variety of MHC genes (PBS, 2001). MHC stands for major histocompatibility locus. These are “genes code for special protein markers that are attached to the surface of cells and help the body recognize whether a cell belongs to an organism or if it is an invader such as a bacteria or virus” (Woronczuk et al., 1999).
In this experiment the male participants were asked to wear T-shirts to wear for two nights. These t-shirts were then placed in a box armed with a “smelling hole” (PBS, 2001). The female participants were then invited to sniff the boxes and rate the odors according to “intensity, pleasantness, and sexiness” (PBS, 1999). Results showed that women were attracted to the smells belonging to men who were MHC different from themselves. It then can be concluded that an individual would be attracted most to a person who is genetic immunity to disease differs most from our own thus producing stronger, healthier children (PBS, 1999).
Interestingly, in another similar study conducted by Richardson (1996), it was found that women with similar MHC genes with specific males would be reminded of her brother or father. On the other hand, dissimilar MHC genes would remind her of a past or current boyfriend (Woronczuk et al., 1999). Another interesting finding of this research is on how this had an opposite effect on women who were using birth control pills. The article proposes that the birth control pill probably “trick[s] the body into thinking its pregnant, and women on the pill often report that they prefer smells that remind them of home and relatives” (Woronczuk et al., 1999).
(Hmmm....disturbing.....).
Anyway.....
Research on human pheromones is yielding intriguing results. Furthermore, it seems that human pheromones offer promising implications and uses in bettering female health and understanding attraction. So far, the author can see a variety of benefits pheromones knowledge can bring to human kind. This includes: menstrual regulation for those with irregular periods, fertility and conception problems, genetic disease prevention, and marital/couple therapy. Indeed, with the continued study of this relatively new concept applied to humans, the possibility of its uses and benefits to human kind are endless.

Fear and Pheromones
Pheromones are used for communication within a species. When an organism releases pheromones, it elicits either an overt or physiological reaction in the receiving organism of the same species (Carlson, 2007, p. 271). Pheromones were originally studied in insects. For instance, it was found that when ants rub their antennas together they are exchanging pheromones to confirm each other’s species and colony identity (Seppa, 1998). Later studies extended to smaller animals such as mice ( as previously discussed in Physiology and reproduction as posted on 1/10/10. e.i Lee-Boot effect and Whitten effect).
Research and interest on human pheromones is relatively new concentrating mainly on sexuality and attraction. It was interesting to find another angle of study on this interesting subject.
Apparantly, it has been discovered that there is a pheromone for fear. An article in The Pretonia News (2008) cited a research study that investigates whether sweat can give out signals that might subconsciously be picked up by others. US researchers collected sweat from 40 novice sky divers as they fell of to the earth by taping absorbant pads to their armpits. A second group of of volunteers were asked to smell the samples while having their brain scanned. It revealed increased activity in the areas of the brain associated with fear and emotional responses---the amygdala and hypothalamus (The Pretonia News, 2008).
The potential of the fear pheromone apparantly has peaked the interest of many scientist and researchers. At this time, the City University of London with the support of The Home Office Scientific Development Branch is developing the technology to produce two sensors that can "detect the unique chemical signiture of the fear pheromone" (Zolfagharifard, 2009). These devices will be specifically designed to identify terrorist at airport security checks and high profile events.This technology is foreseen to be developed within the next two to three years (Evening Chronicle, 2009).
There have also been reports of isolating the fear pheromone for warfare purposes. An article by Randerson (2008) cites the US Defense Advanced Research Projects Agency, otherwise known as "DARPA" as one oganizational group funding this type of study. He further speculates the possibility of its use in inducing terror in enemy troops. DARPA, of course, denies that they will further fund any more research of this field or that it plans to use fear pheromones for military purposes.

US researchers collected sweat from 40 novice sky divers as they fell of to the earth by taping absorbant pads to their armpits. A second group of of volunteers were asked to smell the samples while having their brain scanned. It revealed increased activity in the areas of the brain associated with fear and emotional responses---the amygdala and hypothalamus (The Pretonia News, 2008).
The potential of the fear pheromone apparantly has peaked the interest of many scientist and researchers. At this time, the City University of London with the support of The Home Office Scientific Development Branch is developing the technology to produce two sensors that can "detect the unique chemical signiture of the fear pheromone" (Zolfagharifard, 2009). These devices will be specifically designed to identify terrorist at airport security checks and high profile events.This technology is foreseen to be developed within the next two to three years (Evening Chronicle, 2009).
There have also been reports of isolating the fear pheromone for warfare purposes. An article by Randerson (2008) cites the US Defense Advanced Research Projects Agency, otherwise known as "DARPA" as one oganizational group funding this type of study. He further speculates the possibility of its use in inducing terror in enemy troops. DARPA, of course, denies that they will further fund any more research of this field or that it plans to use fear pheromones for military purposes.

Alcohol, Men, and "Oh, I didn't Know...."
Here's an excerpt from an really interesting article on unlawful sex with a minor. Thought, comments, reactions. Welcome.
An article from Egan and Cordan (2009) reads:
"One 'reasonable ground' for unlawful sex with a minor is mistaken age. Alcohol consumption and make-up afe often deemed further influences in impaired perception. Two hundred and fourty persons in bars and cafes rated the attractiveness of composite faces of immature and mature females with and without additional make-up, alcohol users having their concurrent blood-alcohol level measured using a breathalyser. A non-sex preference for immature faces over sexually mature faces were found. Alcohol and make-up did not inflate attractiveness ratings in immature faces. While alcohol consumption significantly inflated attractiveness ratings for for participants viewing made-up faces, greater alcohol consumption itself did not lead to overestimation of age. Although alcohol limited the processing of maturity cues in female observers, it had no effect on the age perception of males viewing female faces, suggesting male mate preference are not easily disrupted. Participants consistently overestimated the age of sexually immature- and sexually immature-faces by an average of 3.5 years. Our study suggests that even heavy alcohol consumption does not interfere with age-perception tasks in men, so it is not of itself an excuse for apparent mistaken age in cases of unlawful sex with a minor. "
Hmmmm.......

Social Anxiety Disorder
The cognitive paradigm stresses the cognitive aspect of learning. It attemps to understand behavior and learning through the understanding of thought processes. Gestalt theorists, Jean Piaget, Edward Chace Tolman, and Albert Bandura mainly operated within this school of thought. Cognitive theorists such as those mentioned, reject behaviorism on grounds that complex behavior are not merely a matter of cause and effect but of one’s ability to make logical choices as to what makes the most sense. It is undeniable that social anxiety is one disorder that involves maladaptive cognitive processing. Unfortunately individuals possessing this disorder choose to engage in maladaptive behavior that not only contributes to its development but to its maintenance as well.
What is Social Anxiety Disorder?
Social anxiety is experienced when one feels the pressure to make good impressions yet is doubtful of their social abilities. Social anxiety is considered normal and adaptive when this is used constructively in job interviews, first dates, and meeting new people. It becomes maladaptive when the emotion is used primarily to avoid social situations (Schlenker & Leary, 1982). According to the Mayo Clinic (2009) social anxiety disorder, also known as social phobia, include signs and symptoms such as intense fear of being in situations that is unfamiliar, where one may feel judged, and where others may notice feelings of discomfort. Other signs are worrying about embarrassing oneself and avoiding doing things or speaking to others for fear of embarrassment (para 2). People labeled as shy and introverted may have social anxiety disorder but this is definitely not always the case. Shyness is a common individual characteristic mildly resembling the disorder. Social anxiety disorder is an extreme form of shyness.
Many individuals with social anxiety disorder report that they have been socially anxious since childhood. Temperamental shyness begins from infancy with it being characterized by face and eye contact avoidance (Brunet, Mondloch, and Schmidt, 2010). Brunet et al. (2010) conducted a study on temperamental shyness in children and found that shy children are less able to distinguish certain facial emotions in others. Perhaps this may be due to lessened sensitivity to certain facial cues leading to secondary negative effects in social behavior seen later on in life.
Bandura’s Observational Learning
Bandura’s observational learning contends that humans naturally imitate what they see others do (Hergenhan & Olson, 2005, p. 341). In applying this to children, it is natural to conclude that children learn from their parent’s behavior. Children of socially anxious parents tend to become socially anxious themselves. This is probably compounded by the pressure parents place on their children to make good impressions on others as they themselves are concerned over others opinions of themselves. One of parents many responsibilities as role models to their children is modeling and helping their children cope and navigate in the social world. Unfortunately, because of their inability to cope socially themselves, their children grow up to be socially isolated as well. These parents fail to offer their children opportunities to interact with others which prevent their children from learning that social interactions can be enjoyable and gratifying. It also communicates to their children that social situations should be feared.
Divorce and parent separation also have effects on children’s cognitive processing. It is found that children of divorce and separated parents witnessing marital and verbal aggression are factors that cause social phobias. Another factor to consider when it comes to parenting is parent-child attachment. Insecure attachment or lack of close relationships with an adult has been shown to cause shyness. As one navigates and learns social norms and etiquette, social schemas are developed.
Parent-child relationships and attachment are the earliest interpersonal relationship that a child comes to experience and as such have direct impact to personality development. Securely attached children have “attentive and responsive” parents; insecurely attached children have parents who are undependable, rejecting, and lacking in warmth (Ledley & Heimberg, 2006). It was found that children who formed secure parental attachment were more socially active, more popular, and less socially anxious. Early attachment patterns can influence the development of beliefs about social relationships. Secure-attached children come to “see others as accepting and dependable” while those that do not “see others as critical and unreliable” (Ledley & Heimberg, 2006).
Perceived Self Efficacy versus Real Self Efficacy
Bandura also believed in self regulation of behavior and how it relates to perceived
and real self efficacy. Bandura believed that human behavior is mainly self regulated. Perceived self efficacy is a person’s belief about his capabilities. It determines how one motivates oneself, think, feel, and behave. It develops from personal accomplishments and failures. It also arises from seeing others who are like oneself fail and succeed. High self efficacy means internal locus of control. Because of this they tend to try, accomplish, and persist more. Individuals with low self efficacy have external locus of control which makes them fearful. Individuals tend to experience fear in events over which they have no control and therefore are uncertain of (Hergenhahn & Olson, 2005, p. 350).
Individuals with social phobias have a distorted image of how they are perceived socially. Because of their avoidance to face and eye contact they tend to miss certain social cues. Attention is focused inward unto themselves and on how they believe they are coming across to others. For individuals who are socially anxious, it is difficult to place their focus and attention to the social situation at hand. Rather, focus is placed on how they feel they are coming across and what is going on internally.
Model of Looming Vulnerability
Looming Vulnerability models depicts a cognitive style that evaluates and overestimates threats represented in environment. This model is based on the assumption that all organisms must be able to distinguish between increasing or decreasing threats in order to survive. For the well adjusted, perception is an accurate appraisal of a given situation, for the maladjusted it is not. The looming vulnerability cognitive style then relates to how one experiences an exaggerated state of danger or rising risk of threat. According to Riskind, Williams, and Joiner (2006), the looming cognitive style “functions as a danger schema that biases information processing, activates worry, and other defensive or compensatory behavior.
Numerous studies suggest that attention, judgment, and interpretation biases exist in those with social anxiety disorder. Studies involving Stroop and Dot-Probe tests investigate these biases and how the role the play in the development and maintenance of this form of anxiety. In a Stroop test participants are shown words written in various ink colors. Participants are then asked to say the ink color. Individuals with the disorder were slow to respond indicating that they were preoccupied with the meaning of the word rather than attending to the color. In the dot test, participants were showed either words or faces where one of which was neutral in emotion and the other containing emotional valence (such as socially threatening words, angry faces). A dot then replaced one of the words/faces. Socially anxious individuals were found to respond more quickly when the dot was placed in the emotionally charged word/face and reacted slower for the neutral word/face. Both the Stroop and the dot test studies demonstrate attention biases. That is, individuals with social anxiety disorder have a tendency to attend to stimulus that they find threatening (Ledley & Heimber, 2006).
Judgment and interpretation biases also exist for the social phobic. They also are likely to think that other people interpret physical symptoms they are showing such as blushing, shaking, or sweating as signs of anxiety problems or other psychiatric disorder (Ledley & Heimber, 2006). Because of how their information processing works, they fail to consider that others might be seeing these physical symptoms as merely being hot, cold, or tired. When recalling social situations, those with social anxiety disorders interpret ambiguous situations negatively although they are positive interpretations can be applicable. They are also predisposed to judge themselves negatively than they are actually judged and would judge others in similar situations. Cognitive processes of the socially phobic see social events as a threat because to them it is a means to potential of public embarrassment, criticism, and disapproval. They, in short, will generate threatening circumstances in their mind of rapidly intensifying danger of social rejection.
Life space and Law of Pragnanz
Gestalt psychology works mainly inside the frame of the cognitive paradigm. Gestalt theorist contends that humans (and animals for that matter) think in terms of wholes. That is, stimuli are configured on what they mean as a whole unit. Kurt Lewis, a gestalt psychologist, came up with the concept of life space to explain human motivation and behavior. Life space, according to Lewis, is the sum of all psychological facts. Psychological facts pertain to anything and everything an individual is aware of at any given point in time. It is its whole that then determines behavior. Unfortunately, the psychological facts the socially anxious deals with are negative beliefs full of distortions and biases in the processing of social information.
Another concept coming from Gestalt paradigm is Koffka’s Law of Pragnanz. It basically answers the question, “How does the mind organize sensory information and make it meaningful?”(Hergenhahn & Olson, 2005, p.270). It contends that thoughts are already pre-organized before it is even experienced. That is, external stimuli are actively transformed by the brain and it is this transformed information of which one becomes conscious of. Our conscious experiences therefore of events are a result of the brains interpretation of external stimuli.
Socially anxious individuals have an avoidance tendency to divert attention away from faces. On doing so, they miss out on important cues to make conversation go along smoothly. Eye contact is also avoided which can make them seem that they are lacking in social skills, are disinterested, or are uncomfortable. Interestingly, they will tend to seek out negative cues from people with whom they are interacting with. These cues include yawning, the person discontinuing the conversation, and the person gazing around room. Perhaps they choose to look for negative cues as this confirms their perceptions of self simply because this is the information and situation that they are most used to and comfortable with.
It is important to recognize if one’s cognitive style causes anxiety in social situations as awareness and knowledge can serve as a means of prevention and intervention not only for the adult affected but for subsequent generations as well.

Industrial Psychology: Managers and Leaders
When I worked as an Operation Analyst for JPMorgan I often would work with a Regional Manager on which state the machine (usually an ATM) was located. There was one specific manager who was obviously knowledgeable about ATMs, and from what I could tell, was a very hardworking man. If one of his ATMs broke down, I would get it running as fast as possible. I worked hard for him because I respected his leadership, sincerity, and enthusiasm. He always took the time to explain with logic and sound reasoning. I could also see that he was working alongside of me and not simply demanding I do this or that. He led by example and logic which earned my highest respect. To me, this is strong leadership.
In all my years in the workforce, I have encountered many managers and truthfully, a very few leaders. The understanding gained from learning industrial psychology and the impressions I have gathered from personal experiences have lead to me to believe that management is a position anyone can hold. It is a title given to someone with the belief that this person can “manage” (and hopefully lead). It is simply a matter of “hit and miss” whether or not that person has leadership qualities. Being a manager involves: “planning, organizing, controlling, and leading” this basically can be interpreted as “administrative work (Dubrin, 2004).Leadership is much more than that. It involves the right personality and qualities that have been honed and developed that can “inspire(s) and energize(s) people and bring(s) about change” (Dubrin, 2004). Among those personalities and qualities are passion and enthusiasm, self-confidence, insight, courage, and sense of humor. Leaders also possess distinct skills and behaviors among them are: direction setting, trustworthiness, high standards, accessibility, and supportiveness.
I personally think that this distinction needs to be recognized primarily by those who are responsible for hiring as well as promoting individuals within the company. In order for a company/business to really thrive, it needs leaders. If one cannot recognize and distinguish the leaders from the non-leaders, then one is basically staffing a company to achieve mediocre success with a higher probability of failure.

Understanding Anorexia Nervosa using Theories
Clinicians and researchers work on a basis of theories to analyze the given information and understand how the different aspects of a person’s life combine to contribute to maladjusted behavior and ultimately to mental illness.
____________________
Anorexia Nervosa
Individuals with this condition have a distorted concept of their body image. They see themselves as overweight despite being 85% below normal weight. The irrational fear in becoming fat leads to unusual behaviors and physical manifestations. These behaviors include refusing to eat, excessive exercising, and social withdrawal. Physical symptoms include weakness, muscle aches, sleep disturbances, and amenorrhea. Many individuals with anorexia nervosa have obsessive compulsiveness and obsessive compulsive disorders (Crane, Roberts, and Treasure, 2007). Behaviors that support this are seen in how they restrict their food intake. For one, they tend to develop rituals in their choosing, preparing, and ingesting of meals. Although they do not eat the food themselves, they take great delight in preparing the meals for those around them such as spouses and children. When they do consume food rituals such as counting chews per bite and rearranging food on their plate is a constant preoccupation. Another behavior that seemingly supports this is their compulsion for excessive exercise. Individuals with anorexia tend to stick to routine in their daily life as well as in their exercise habits. The try to avoid situations where there might be pressure to eat and when they are with others, they often decline to eat. Because of this, they are inclines to isolate themselves from other people.
Statistics show that the most susceptible ages are 14 and 18 years of age with 90% of which are females (Sarason, 2005). Success rate are also not particularly encouraging. In 1991, only 29% treated resulted in good recoveries; 15% died of suicide and other complications of the disease (Ratnasuriya, Eisler, Szmukler, and Russell, 1991).
Major Theories
As mentioned earlier, clinicians and researchers typically look through the “lens” of theories in order to understand and analyze gathered information. Currently, there are six theoretical perspectives that are commonly used today. These theories are: (a.) the biological perspective, (b.) the psychodynamic perspective, (c.) the behavioral perspective, (d.) the cognitive perspective, (e.) the humanistic-existential perspective, and the (f.) the community-cultural perspective.
Biological Perspective. This perspective calls attention to the role of bodily processes. It assumes that bodily processes such as inherited defects in genes, acquired defects (such as those acquired through injuries and accidents), and hormonal and neurological imbalances can be pinpointed to explain disorders. It recognizes that the body and mind are interrelated and affect each other. In anorexia, hereditary factors specifically physiological mechanisms are suspected. Changes in biochemicals levels that play a role in the control of metabolism and eating such as norepinerprine, serotonin and opioids are seen in people with anorexia (Fava, Copeland, Schweiger, and Herzog, 1989).
Psychodynamic Perspective. The psychodynamic perspective places emphasis on the role of anxiety and inner conflict. It sees thoughts and emotions as important determinants to one’s actions and reactions. Furthermore, one has to look into deeper emotions and feelings to understand troubling behavior. It is interesting to note that while anorexics have a preoccupation with self image, the real issue lies in the lack of self worth (Mayo Clinic, 2010).
Behavioral Perspective. Here, behavior is shown as merely a product and response to environmental stimuli. That is, learning molds behavior thus personality. Behaviorist Ivan Pavlov is known for his infamous classical conditioning experiment. The experiment basically sheds light on the impact of stimuli on behavior. In manipulating external factors behavioral responses change and adjust. Mothers, for instance, may show over concern over their daughter’s weight and physical attractiveness serving as negative stimuli to a daughter’s concept of self worth and identity. Childhood sexual abuse, certain characteristics of family environment, and other early traumatic events are also possible contributors to the condition (Svirko & Hawton, 2007).
Cognitive Perspective. Cognitive perspective based theories examines internal mental processes with an emphasis with mental interpretations and problem solving. In abnormal psychology, it looks for defective thinking as the root of an abnormal behavior. Individuals with anorexia have an impaired ability to process information. The cognitive distortion obviously lies in their ability to interpret their emaciated physical appearances as they continue to think that they are overweight. When clinicians are looking at a disorder through a cognitive perspective, they often use cognitive therapy in conjunction with other treatments. Although there is much variation to different types of cognitive therapy, they normally share three basic assumptions: (a.) Cognitive activity affects behavior, (b.) Cognitive activity can be monitored, and (c.) Behavior change can be achieved through cognitive change (Sarason, 2005).
Humanistic-existential Perspective is an optimistic theoretical approach that emphasizes on individuality and how we have the freedom to make our own decisions. It is has a spiritual context to it not found in other theories. While there is not a lot of back up research to support it, many clinicians see it as an effective approach to rehabilitation. An article by Aida Warah (1993) looks at the anorexic’s compulsion to excessively exercise. It hypothesizes that “overactivity may help the anorexic person achieve a sense of existential permanence by dynamizing her static and too rational mode of being.”.(Warah, 1993).
Community-cultural perspective. This approach looks into the role of culture and community has in contributing to maladaptive behavior or disorder. Western culture and other industrialized countries, for instance, hold thinness as a desirable physical characteristic in individuals especially in women. Obesity is considered undesirable and in fact is associated with many negative stereotypes. A few of which include lazy, unintelligent, and uneducated. Western media also holds a powerful influence in the attractiveness of being thin.
Maladaptive Behavioral Patterns
A behavior is considered maladaptive when it leads the individual to experience a great deal of anxiety, stress, and unhappiness when presented with stressful situations and inner conflict. Individuals with maladaptive behavior tend to have a narrow spectrum on how to act and react. When significant changes happen in his environment, he is unable to adapt and respond appropriately sticking basically to his original way of thought and action. Long term maladaptive behaviors, especially when having an onset from childhood are considered personality disorders. Other features of personality disorders include: (a.) stability-with the behavior being fairly consistent and evident, (b.) pervasive-apparent in social, personal, and occupational areas in life, and (c.) “clinical significant maladaptions resulting in personal distress or impairment in social and occupational functioning” (Sarason, 2005).
Personality disorders falls under three major categories. The first category is odd and eccentric behaviors. Under this category characteristics are the paranoid (tense and guarded), schizoid (restricted emotional expression), and schizotypal (unsettling and peculiar thoughts, appearance, and behavior). Its clinical features include social deficits, absences of close personal relationships, and holds poor prognosis. The second category is dramatic, emotional, or erratic behaviors. Under this are the histrionic (seductive behavior and instant gratification), narcissistic (Self absorbed, expecting special treatment), borderline (unable to be alone), and antisocial (exploitive, manipulative, lack of guilt). Characteristics that they share are social and interpersonal instability yet having the condition improve as they age. The last and third category is anxious or fearful behavior. They include the avoidant (avoiding unfamiliar people, places, events to avoid being embarrassed), dependent (fear of abandonment, needs to be with somebody at all cost), and the antisocial (preoccupied with details, perfectionist).

Anorexia Nervosa
Individuals with this condition have a distorted concept of their body image. They see themselves as overweight despite being 85% below normal weight. The irrational fear in becoming fat leads to unusual behaviors and physical manifestations. These behaviors include refusing to eat, excessive exercising, and social withdrawal. Physical symptoms include weakness, muscle aches, sleep disturbances, and amenorrhea. Many individuals with anorexia nervosa have obsessive compulsiveness and obsessive compulsive disorders (Crane, Roberts, and Treasure, 2007). Behaviors that support this are seen in how they restrict their food intake. For one, they tend to develop rituals in their choosing, preparing, and ingesting of meals. Although they do not eat the food themselves, they take great delight in preparing the meals for those around them such as spouses and children. When they do consume food rituals such as counting chews per bite and rearranging food on their plate is a constant preoccupation. Another behavior that seemingly supports this is their compulsion for excessive exercise. Individuals with anorexia tend to stick to routine in their daily life as well as in their exercise habits. The try to avoid situations where there might be pressure to eat and when they are with others, they often decline to eat. Because of this, they are inclines to isolate themselves from other people.
Statistics show that the most susceptible ages are 14 and 18 years of age with 90% of which are females (Sarason, 2005). Success rate are also not particularly encouraging. In 1991, only 29% treated resulted in good recoveries; 15% died of suicide and other complications of the disease (Ratnasuriya, Eisler, Szmukler, and Russell, 1991).

Irresponsible behavior and the Brain
The orbitofrontal cortex is one of the areas of the brain that help process emotional input. It serves as an interface between brain functions that engages in automatic and controlled responses. It is also recognized for the important role it plays in making moral judgments. According to Carlson (2005) damaged to this area would therefore cause a person to be unable to “make or carry out plans…his actions appear(ing) to be capricious and whimsical”. Carlson also points out that while damage results in the inability to act in a responsible and mature fashion, he also notes that the damage would not hinder him from accurately assessing situations from a purely theoretical perspective. He illustrates this point by citing a patient with bilateral damage (damage to both sides of the brain) to the area who displayed excellent social judgment. When questioned about hypothetical situations involving moral and ethical dilemmas, the patient answered sensibly and with justifiable logic. Yet, in his own life, he was unable to tell the difference between trivial matters and important ones. For instance, he would spend many hours deciding where to eat dinner but was unable to make judgments involving occupation and family (such as squandering the family life savings and making very bad financial decisions).
Learning about the orbitofrontal cortex and how it relates to behavior brought on strong emotional responses in me. It is outrageous to think that the undevelopment, damage, or absence thereof of this region can serve as an excuse for irresponsible and insensitive behavior. Should individuals with behaviors described above be excused because maybe they have something wrong with their orbit frontal cortexes? What if that person was a father or a spouse? How should a wife cope with that knowing that the behavior is practically beyond one’s control? How should society be asked to deal with it?
I guess the best thing to do is to get professional help to gain ways to cope with this unfortunate affliction/brain damage. I’m sure there are ways in which relationships can still be worked out with proper techniques and a great deal of patience and understanding. What this topic particularly hit home to me is that irresponsible behavior may not be a matter of just will and wants. It’s also about what a person is capable physiology-wise/brain-wise of.

Physiology and Reproduction
Reproductive Behavior. There are a couple of things I found interesting about reproductive behavior and it’s physiology. One of them is the effects of pheromones. Pheromones are chemicals released by one animal that affects another. Four occurrences observed in mice are associated with the release of certain pheromones. They are: (a.) the Lee-Boot effect, (b.) the Whitten effect, (c.)Vandenberg effect, and (d.) the Bruce effect. The Lee-Boot effect occurs when estrous cycles of a group of females ceases in the absence of a male. Yet, estrous cycles reappear when exposed to male urine with the cycles being synchronized (the Whitten effect). The Vandenberg effect refers to the early onset of puberty of a female caused by the odor of a male. Lastly, the Bruce effect happens when a pregnant female aborts--triggered by the odor of urine from another (assumingly with better genetic make up) male.
What makes pheromones very interesting is how it seems to promote the survival of the species. The Bruce effect in particular reiterates the survival of the fittest. Interestingly as well is the fact that female humans also experiences occurrences similar to the Whitten effect and the Lee-Boot effect. It would explain how women who have very close relationships seem to get pregnant at the same time. Probably this is because they ovulate at the same time as well.
Studies on pheromones usually involve animal research. The influence of pheromones is observed in species such as mice, bees, and beetles. This knowledge can be used to the benefit of insect and pests control and even elimination. When I grew up in the Philippines, insecticides were used to protect the crops. If someone could come up with a way to use this knowledge, this could be a safer and more eco-friendly alternative to harmful chemicals and insecticides. Also in the Philippines there is a certain “black magic” that we call “gayuma”. Funny thing is, there might be “magic” in it after all. Gayuma, from what I recall is a love potion made from a person’s sweat. The person who is trying to attract the attentions of a particular person (romantically) is to exercise intensively, collect his/her sweat, and mix it in a strong drink (such as the local alcohol) and give it to the person they are trying to attract. (This is done over a period of a few weeks.) I used to disregard this as superstition but upon learning about pheromones, I have to say there might be something to it. I am surprised that perfume manufacturers haven’t thought about putting urine, sweat, and other body by products into their merchandise (Or have they? Good thing I am not particularly fond of perfumes). Well, at the very least, this explains why wives like to smell their husband’s armpits. Wouldn’t it be funny if therapists start recommending couples to smell each other’s armpits twice a day? You never know, it might actually work. If nothing else, there’d be a lot of laughing involved :)
I think that the so called superstitions, myths, and etc. needs to be looked into more closely and tested scientifically. There are so many things that may open our eyes and may give us solutions to issues we have today.

Child obesity and depression
Can the increasing condition of obesity in children and adolescence negatively affected their social relations? If so, would it be safe to assume that the stigma of being obese would lead to overweight children having a greater tendency towards depression? It is my intent to describe this growing epidemic as well as to understand the relationship between obesity, social interactions, and depression in children. It is my theory that obesity leads to stigmatized children which in turn increase the predisposition towards depression.
Obesity among children is on the rise. It threatens children’s physical and emotional wellbeing. The Centers for disease control and prevention (2009) show that over the past 20 years, obesity has more than doubled in children age six to 11 from 6.5% in 1980 to 17% in 2006. In children ages 12 to19 this number has more than tripled. This increase is from 5% to 17.6%. Calculations of child obesity were done by figuring body mass index (also known as BMI) which measures weight in relation to height. A child is considered overweight when belonging at or above the 85th percentile and obese when BMI is at or above 95th percentile for children at the same age and height.
What has caused this alarming increase of this epidemic in children? Among the usual reasons as to weight gain include lack of physical activity and poor genetics. Yet, another substantial concern is today’s society is that of deteriorating eating habits. According to the National Health Review (2008) family income affects a child’s inclination to gain weight. Also, low income families tend to eat more filling starchy foods such as rice, bread, cakes (Echwald, 1999). Families with higher income tend to eat more vegetables.According to recent meta-analysis, individuals of low socioeconomic statuses are prone to depression (Johnston, Johnson, McLeod, and Johnston, 2004). Other culprits to consider are the readily available food choices out there that are high in sugar, salt, and fat contents. These foods are accessible everywhere including vending machines, restaurants, and grocery stores. Many unhealthy food products today are also heavily marketed to target young and impressionable minds. With unhealthy family choices and negative food industry influences affecting children’s eating habits, unhealthy eating is common and has become natural to children (Nutrition Health Review, 2008). These conditions, aggravated by the fact that parents often use food as reward, all contribute to this increasing problem of child obesity.
Obesity is not only detrimental to our children’s physical well being; it is also detrimental to their emotional wellbeing. There is a stigma in being obese. This is especially true in industrialized countries where thinness is considered beautiful and the opposite is not (Myers, 2008). Another study found an association between obesity and self esteem in children as well as adolescence (Cited in Lowry et al., 2007). A study conducted in Australia by Hesketh and colleagues (2004) confirmed this. They conducted a three year longitudinal study of children and found that seven year olds with higher BMIs modestly predicted lower self esteem than other peers their age. In children age 11, higher BMIs became a stronger predictor of low self esteem.Yet, self esteem in obese preschool children remain unaffected (Strauss and Pollack, 2003).It is not surprising that overweight female adolescents are more impacted emotionally than their male counterparts. Overweight females often expect to be rejected and go into withdrawal (Monello and Mayer, 1963). Overall, they have found, both sexes experience more occurrence of depressive symptoms than their normal weight peers.
Depression is a mood disorder that goes beyond temporary feelings of sadness ( Papalia, Olds. and Feldman, 2008). Depression affects self esteem and one’s sense of self efficacy. Some of the characteristics of depression are lack of concentration, fatigue, indifference to physical activity, and feelings of worthlessness and friendlessness. Dr. William L. Coleman, a professor of pediatrics at the Center for Development and Learning at the University of North Carolina in Chapel Hill, states that there has been an increase of 15 percent in depression among school-age children over the last five years (Cited in Colino, 2004).
There are other factors that are influencing this negative outlook when it comes to obesity in children. For one there are Ethnic influences involved. For example, 13 to 14 year old White and Hispanic females who are overweight convey lower self esteem issues than their normal weight counterpart. However, 13 to 14 year old African American females regardless of weight did not show a difference in self esteem. This indicates that American Africans may be more accepting of larger body sizes than Whites or Hispanic whose negative view regarding larger set weights explain for the declined self esteem and tendency towards depression of their young children (Lowry et al., 2007).
A link has been found on low self esteem in relation to peer victimization and the lack of social support (Sweeting, Wright, and Minnis, 2005). Peer victimization focuses on appearances and body weight. Obese children are more prone to be negatively affected by negative peer comments and remarks. Overweight kids are seen by other kids as the least desirable of friends. It may be for also this reason why obese children may be prone to be isolated socially and be on the sidelines of social networks. Peer victimization is also one of the causes of depression in obese children and adolescents. It is easy to see how peer victimization on obese children can lead to both self esteem issues as well as depression. Alarmingly, there is a positive correlation between depressive symptoms at age six to nine years of age and being overweight later on in life. (Liem, Sauer, Oldehinkel, and Stolk, 2008).
A study conducted by Strauss and Pollack (2004) investigated the social networks of overweight and normal weight adolescents. Although overweight adolescent listed the same number of friends as their normal weight counterparts, the results of the study does not show in support of this.
In the study mentioned above, an impressively large sample of 90,118 was taken from the National Longitudinal Study of Adolescent Health. It included 13 to 18 year old kids who were both of normal and overweight weights. In the study, overweight was defined as having a body mass index (BMI) of 95> percentile for age and sex. The method used was of friendship nominations each adolescent received from others. Each participant was allowed 5 best female and 5 best male friends. In and out degree measurements were made. This means that it measured the number of nominations each individual received from other students and the number of nominations that participant made to identify as friends. It also took into consideration extended networks such as friends and friends of friends. Calculations of connections and degree of relationships were then made by matrix programs.
Results show that overweight participants were significantly less popular than normal weight participants with a significant level of p<.001. Overweight participants are less likely to receive 5 friendship nominations and less likely to receive 2 or best friend nominations. On the other hand, those who were nominated by overweight participants as friends were less likely to return the nominations. Results also show that normal weight participants had about the same mean number of nominated friendship ties as others reported about them (means of 4.58; 4.79). In contrast, overweight participants nominated more friendship ties with others than they actually received from others (means of 4.29; 3.39).
Myers (2008) states that establishing of friendship relationships is an essential part of social development. It enables children to learn how to communicate, cooperate, and learn about intimacy. It also gives children the opportunity to learn how to resolve differences and conflicts. Because of the stigma that overweight children receive, overweight children have lesser opportunities to establish and build these relationships thus damaging their self efficacy on their ability on making friends.
Being rejected by peers and friendlessness has long term effects. Bagwell, Newcomb, and Bukowski (1998) conducted a longitudinal study that showed fifth graders who were friendless had a greater tendency to show depressive symptoms and low self-esteem long way into adulthood (Cited in Myers, 2008). Social isolation from peers as well as peer victimization can lead to feelings of loneliness. According to Myers (2008) lonely people tend to view others and oneself negatively. They experience a loss of confidence in their socialization skills and blame themselves for their poor social relationships. These negative thinking brings about depressive moods (Myers, 2008).
The Endocrine Society (2009) reports a study on how elevated levels of cortisol relates to depression. Cortisol is a steroid that is released in response to stress. It is also responsible for converting fat into energy. The sample size in this study is a total of 50 obese children and teenagers of which 20 were boys and 30 were girls with ages ranging from eight to 15 years of age. Prior to the study, they were not diagnosed with depression. These children were patients at Athens University pediatric clinic. A questionnaire assessed their symptoms of depression.
Cortisol normally is elevated during mornings, tapers off late morning, and is low at night. In this study, Pervanidou and colleagues took saliva and blood samples from the participants to check their cortisol levels. Results are summarized by lead researcher and author, Dr. Panagiota Pervanidou of Athens University Medical School in Athens, Greece as he states, “There is evidence in adults that abnormal regulation of cortisol plays a role in both obesity and depression. ”
The fact that obese individuals produce higher levels of cortisol which is also the hormone responsible for depression indicates that depression is not only induced by external influences but is internal as well. It further indicates that with external factors and internal hormonal balances such with that that is associated with obesity; there is a more increased tendency for these individuals to show symptoms of depression.
In another article by Carol Hilton (2002) cites a study conducted by endocrinologist Dr. Ronnie Aronson who conducted a study that examined the effectiveness of different approaches to weight loss. The sample consisted of 141 overweight patients. 86 of these patients were successful at losing weight and were able to maintain (with some further losing more weight) after a nine month follow up. Within this study it was found that with weight loss, participants reported to be less depressed. Another interesting fact about this study is that elevation of mood and depression from weight loss is actually better than results from antidepressants. Yet, Dr. Aronson cautions that this elevation of depression should not be correlated to weight loss since it could be the frustration of the attempts and the failure thereof that may be the stronger indicator of mood elevation.
Wilson Lawson (2003) writes an article entitled, “The puzzle of obese children and depression.” This article basically expresses the “chicken and egg dilemma”. Mainly, which comes first, depression or obesity? It cites a study in Pediatric that followed almost 1,000 children in North Carolina over a period of eight years. Respondents were from ages nine to 16. They found that the more the child is overweight, the more likely the child is at risk for depression. Yet, Dr. Sarah Mustillo, a researcher in psychiatry and behavioral sciences at Duke Medical Center, that depression causes obesity when a child becomes too depressed to do any physical activity.
Conclusion
Obesity and depression has become an increasing health risk to children and adolescents. Many factors contributing to obesity is the convenience and trend of unhealthy food and food choices. Unfortunately, this may be tied in with other factors such as low socio-economic statuses and ethnic backgrounds. The social stigma of being obese affects and leads to the deterioration of both self esteem and social efficacy. Without these two beliefs, children do not develop the necessary skills for social interaction. Peer victimization compounds this problem. Peer rejection brings about social isolation and depression. As demonstrated in Strauss and Pollack’s study, social isolation occurs frequently in obese children. Yet, depression in obese children is not affected by behavioral and environmental influences alone. The study conducted by the Endocrine Society indicates that hormonal influences may be partly to blame. The elevated levels of the hormone cortisol were found to be associated with obesity and depression. The study done by Hilton does not believe in the correlation of weight loss and the elevation of depressive symptoms. Instead, it cautions on looking into other factors such as the frustration of unsuccessful attempts of weight loss.

Obesity among children is on the rise. It threatens children’s physical and emotional wellbeing. The Centers for disease control and prevention (2009) show that over the past 20 years, obesity has more than doubled in children age six to 11 from 6.5% in 1980 to 17% in 2006. In children ages 12 to19 this number has more than tripled. This increase is from 5% to 17.6%. Calculations of child obesity were done by figuring body mass index (also known as BMI) which measures weight in relation to height. A child is considered overweight when belonging at or above the 85th percentile and obese when BMI is at or above 95th percentile for children at the same age and height.
What has caused this alarming increase of this epidemic in children? Among the usual reasons as to weight gain include lack of physical activity and poor genetics. Yet, another substantial concern is today’s society is that of deteriorating eating habits. According to the National Health Review (2008) family income affects a child’s inclination to gain weight. Also, low income families tend to eat more filling starchy foods such as rice, bread, cakes (Echwald, 1999). Families with higher income tend to eat more vegetables.According to recent meta-analysis, individuals of low socioeconomic statuses are prone to depression (Johnston, Johnson, McLeod, and Johnston, 2004). Other culprits to consider are the readily available food choices out there that are high in sugar, salt, and fat contents. These foods are accessible everywhere including vending machines, restaurants, and grocery stores. Many unhealthy food products today are also heavily marketed to target young and impressionable minds. With unhealthy family choices and negative food industry influences affecting children’s eating habits, unhealthy eating is common and has become natural to children (Nutrition Health Review, 2008). These conditions, aggravated by the fact that parents often use food as reward, all contribute to this increasing problem of child obesity.
Obesity is not only detrimental to our children’s physical well being; it is also detrimental to their emotional wellbeing. There is a stigma in being obese. This is especially true in industrialized countries where thinness is considered beautiful and the opposite is not (Myers, 2008). Another study found an association between obesity and self esteem in children as well as adolescence (Cited in Lowry et al., 2007). A study conducted in Australia by Hesketh and colleagues (2004) confirmed this. They conducted a three year longitudinal study of children and found that seven year olds with higher BMIs modestly predicted lower self esteem than other peers their age. In children age 11, higher BMIs became a stronger predictor of low self esteem.Yet, self esteem in obese preschool children remain unaffected (Strauss and Pollack, 2003).It is not surprising that overweight female adolescents are more impacted emotionally than their male counterparts. Overweight females often expect to be rejected and go into withdrawal (Monello and Mayer, 1963). Overall, they have found, both sexes experience more occurrence of depressive symptoms than their normal weight peers.
Depression is a mood disorder that goes beyond temporary feelings of sadness ( Papalia, Olds. and Feldman, 2008). Depression affects self esteem and one’s sense of self efficacy. Some of the characteristics of depression are lack of concentration, fatigue, indifference to physical activity, and feelings of worthlessness and friendlessness. Dr. William L. Coleman, a professor of pediatrics at the Center for Development and Learning at the University of North Carolina in Chapel Hill, states that there has been an increase of 15 percent in depression among school-age children over the last five years (Cited in Colino, 2004).
There are other factors that are influencing this negative outlook when it comes to obesity in children. For one there are Ethnic influences involved. For example, 13 to 14 year old White and Hispanic females who are overweight convey lower self esteem issues than their normal weight counterpart. However, 13 to 14 year old African American females regardless of weight did not show a difference in self esteem. This indicates that American Africans may be more accepting of larger body sizes than Whites or Hispanic whose negative view regarding larger set weights explain for the declined self esteem and tendency towards depression of their young children (Lowry et al., 2007).
A link has been found on low self esteem in relation to peer victimization and the lack of social support (Sweeting, Wright, and Minnis, 2005). Peer victimization focuses on appearances and body weight. Obese children are more prone to be negatively affected by negative peer comments and remarks. Overweight kids are seen by other kids as the least desirable of friends. It may be for also this reason why obese children may be prone to be isolated socially and be on the sidelines of social networks. Peer victimization is also one of the causes of depression in obese children and adolescents. It is easy to see how peer victimization on obese children can lead to both self esteem issues as well as depression. Alarmingly, there is a positive correlation between depressive symptoms at age six to nine years of age and being overweight later on in life. (Liem, Sauer, Oldehinkel, and Stolk, 2008).
A study conducted by Strauss and Pollack (2004) investigated the social networks of overweight and normal weight adolescents. Although overweight adolescent listed the same number of friends as their normal weight counterparts, the results of the study does not show in support of this.
In the study mentioned above, an impressively large sample of 90,118 was taken from the National Longitudinal Study of Adolescent Health. It included 13 to 18 year old kids who were both of normal and overweight weights. In the study, overweight was defined as having a body mass index (BMI) of 95> percentile for age and sex. The method used was of friendship nominations each adolescent received from others. Each participant was allowed 5 best female and 5 best male friends. In and out degree measurements were made. This means that it measured the number of nominations each individual received from other students and the number of nominations that participant made to identify as friends. It also took into consideration extended networks such as friends and friends of friends. Calculations of connections and degree of relationships were then made by matrix programs.
Results show that overweight participants were significantly less popular than normal weight participants with a significant level of p<.001. Overweight participants are less likely to receive 5 friendship nominations and less likely to receive 2 or best friend nominations. On the other hand, those who were nominated by overweight participants as friends were less likely to return the nominations. Results also show that normal weight participants had about the same mean number of nominated friendship ties as others reported about them (means of 4.58; 4.79). In contrast, overweight participants nominated more friendship ties with others than they actually received from others (means of 4.29; 3.39).
Myers (2008) states that establishing of friendship relationships is an essential part of social development. It enables children to learn how to communicate, cooperate, and learn about intimacy. It also gives children the opportunity to learn how to resolve differences and conflicts. Because of the stigma that overweight children receive, overweight children have lesser opportunities to establish and build these relationships thus damaging their self efficacy on their ability on making friends.
Being rejected by peers and friendlessness has long term effects. Bagwell, Newcomb, and Bukowski (1998) conducted a longitudinal study that showed fifth graders who were friendless had a greater tendency to show depressive symptoms and low self-esteem long way into adulthood (Cited in Myers, 2008). Social isolation from peers as well as peer victimization can lead to feelings of loneliness. According to Myers (2008) lonely people tend to view others and oneself negatively. They experience a loss of confidence in their socialization skills and blame themselves for their poor social relationships. These negative thinking brings about depressive moods (Myers, 2008).
The Endocrine Society (2009) reports a study on how elevated levels of cortisol relates to depression. Cortisol is a steroid that is released in response to stress. It is also responsible for converting fat into energy. The sample size in this study is a total of 50 obese children and teenagers of which 20 were boys and 30 were girls with ages ranging from eight to 15 years of age.

Music and Emotion
Music elicits emotions. Tone, pitch, note variation, duration, and other factors extracts a variation of responses from us ranging from mere tapping of our feet, the nodding of our heads, to a full blown dance. Less obvious responses are also occurring that we may not be fully aware of. Cardio-respiratory rate changes occur and bio-chemicals such endorphins and dopamine may be released. Recently there has been interest shown towards investigating music and its workings on physiological and biological levels with a main interest of applying its findings to clinical situations. So far, music has been found to be an effective therapy for many neurological and psychiatric disorders including Alzheimer’s, Parkinson disease, depression, dementia, and anxiety. It has also been used in pain management.
Boso et al. (2006) discusses music stimuli and its neurobiological, neuropsychological, and neurophysiological pathways. This was done by discussing the neuroanatomy of the perceptual processing of music, the neuroanatomy of the emotional processing of music, the electrophysiological aspects of music processing, and the biochemical correlates of the musical experience.
Boso et al. presents many interesting points throughout the article. For instance, as they discuss the perceptual processing on music, they note that although music stimuli is normally processed like any other sound (via the auditory pathway), music vibrations also activate skin receptors. Another interesting fact is on how it notes that aside from the normal route of sound stimuli being collected from the outer ear and basically routed to the cochlea, to the auditory nerve, and, consequently, to the auditory thalamus and the auditory cortex, auditory projections are also routed to the amygdala and the medial orbitofrontal cortex, two areas of the brain that play a part in the processing of emotions. According to Carlson (2005), the amygdala is responsible for behavioral, automatic, and hormonal responses. The orbitofrontal cortex, located at base of the frontal lobe, receive and process various input from various regions of the brain including other regions of the frontal lobe. Its input is then dispensed to several areas including the cingulated gyrus, temporal cortex, and back to the amgdala thus affecting behavioral and physiological responses including emotional ones organized by the amygdala (Carlson, 2005). As this article continues to explain the emotional side of processing music, it cites a study conducted by Blood and Zatorre (2001) that discovered how the frontal lobes are activated when listening to pleasant music while the temporal lobes are activated during unpleasant music. Carlson (2005) notes that these two areas plays a role in speech and word recognition.
The article also discusses dopamine, endorphins, endocannabinoids, naloxone, and nitric oxide as biochemicals involved in the musical experience. “Dopamine, which is thought to play a crucial role in the response to naturally rewarding stimuli, may be involved in the enjoyment of music as well” (Boso et al., 2006).This may also be true for endorphins and endocannabiniods released into the bloodstream when listening to music. Naloxone may be responsible for the decrease of pleasant sensations brought about by listening to music. Lastly, nitric acid produces physical reactions by “inducing vasodilatation, warming of skin, and reduction of blood pressure valves” (Boso et al., 2006). The most fascinating fact regarding nitric acid is that it posses antibacterial, antiviral, and immunodulatory functions. The article then speculates if “listening to pleasant music could help to protect the organism against bacterial and viral infections, excessive immune and endothelial activation, as well as the detrimental effects of arterial hypertension” (Boso, et al., 2006).
Electroencephalography, otherwise known as EEG, has been a useful tool in measuring brain responses to music stimuli. Studies using the EEG, “left frontal asymmetry has been associated with positive affect or decreased negative in response to musical stimuli, whereas right frontal asymmestry has been associated with negative affect or decreased positive affect” (Boso et al, 2006). The article also mentions that when using the event related potential technique (ERP), unexpected words produces in a musical melody produces higher peek amplitudes than unexpected words spoken in a sentence. Event-related potentials allows for the separation of small potentials evoked by sensory stimuli from the larger voltage oscillations present in EEGs (Stefanatos & Osman, 2006). The ERP has proven useful in comparing language and music processing.
Carlson (2005) notes that there are two affective disorders that have depressive symptoms namely the bipolar disorder characterized by alternating periods of mania and depression and unipolar depression, a form of depression without the manic episodes. These conditions are particularly dangerous because individuals with this disorders often attempt to commit suicide. They can have very little energy, cry a lot, and unable to experience pleasure. Those with manic symptoms also have bouts of relentless energy and experience feelings of unjustifiable feelings of elation. Currently, these conditions are treated by medication. These medications include iproniazid, tricyclic antidepressants, and specific serotonin reuptake inhibitors. Electroconvulsice therapy (ECT) have also shown effective in the treatment of depression. An article by Tornik, Field, Hernandez-Reif, Diego, and Jones (2003) shows a promising and exciting alternative to the treatment of depression with the use of music as stimuli. In this experimental study where depressive mothers were asked to randomly listen to 20 minutes of either classical or rock music in an effort to understand the effects of music and emotion. This is a longitudinal study with 48 intrusive and withdrawn participating mothers who at the time had infants between the ages of three to six months of age. Intrusive mothers possessed behaviors such as “rough tickling, poking and tugging during interactions, using rapid, staccato movements, and showing tense and fake facial expressions (Torner et al., 2003). Withdrawn mothers demonstrated “flat affects, rare touching, rare vocalizing, disengaged behaviors, and looking away from the infant” (Torner et al., 2003). Power analysis shows that 48 participants for this study would yield an effect size of .40 with a .70 power (Although standard power level is of .80, it is the author’s opinion that the results in this study is quite compelling).
Participants were selected based on three screening measures. These measures include: (a.) Center for Epidemiological Studies-Depression Scale (CES-D), (b.) Intrusive/Withdrawn Interaction Style-Coding, and lastly,(c.) The Behavior Inhibition and Behavior Inhibition and Behavior Activation System Scale (BIS/BAS). The CES-D was used to determine depressive symptoms. The last two tools assessed interaction styles with the second one used as a confirmatory tool.
Actual experimental research was conducted one month after assessments. The women were randomly chosen to listen to 20 minutes of either rock or classical music. Three things were done before and after listening sessions: (a.) EEG was recorded three minutes before and after, (b) saliva samples were taken to measure cortisol levels, ( c.) mood and anxiety questionnaires were given ( questionnaire tools used were The Profile of Mood States-Depression Subscale (POMS) and The State Anxiety Inventory (STAI)).
Results show that all groups showed a decrease in depressive moods using the POM questionnaire tool yet only those intrusive-depressed mothers that listened to rock music showed a decrease in STAI anxiety score. Also, it is only this group of mothers that had significant decreased in cortisol levels shown in their saliva analysis.
As mentioned earlier, EEG is a useful tool in measuring brain responses to musical stimuli. Greater relative right frontal EEG activation is associated with the experience of negative emotions; left front EGG activation is associated with the experience of positive emotions. Yet, the authors on this article would like its readers to consider the corresponding EEG patterns under the broader categories of approach-avoidance emotions. This theory indicates that approach emotions such as joy, interest, and anger activate the left frontal regions and avoidance emotions such as distress and disgust activates the right frontal regions. Thus, if EEG were to measure brain activity before experimentation results would show that the mothers who were intrusive (approach) would exhibit left frontal EEG activation patterns, the mothers who were withdrawn (avoidance) would exhibit right frontal EEG activation.
The EEG for this study then yielded the following results. In general, The EEG showed greater relative right-frontal EEG activation (associated with feelings of distress and disgust) when listening for classical music and left-frontal EEG activation (associated with feelings of joy and interest) for rock music suggests a preference for rock music. “Although the intrusive group EEG values did not differ significantly across music types, the EEG for the withdrawn group suggested less negative (less right-frontal EEG) values for the rock than for the classical music.” (Boso et al., 2006). In conclusion, rock music elevated the moods of withdrawn depressive mothers as the study predicted but classical music did not show any benefit to the intrusive depressive group as originally theorized.
Potential Contributions and Author’s Areas of Learning
Music is something we often take for granted. It seems that instinctively it is understood by anyone and everyone. From its tempo, beat, and lyrics we naturally understand the meaning and the message that it seeks to convey. Music has always been a part of human existence. It is common understanding that different types, tempos, rhythms and such of music elicit different emotional responses within us. What is not common knowledge are the body’s physiological responses. In recent years, music has been an area of interest to be studied in a scientific approach in search of understanding its effects in clinical management in neurological and psychiatric disorders. Both articles mentioned above are such research. They believe that the understanding thereof can make significant contributions in clinical settings.
The first article, “Neurophysiology and Neurobiology of the Musical Experience” brings forth many interesting details such as how music stimuli are not only processed via normal auditory physiological pathways but also activates skin receptors. Another interesting detail presented in this article is how perceived pleasant musical stimuli activated frontal lobes as opposed to the temporal lobes activated by unpleasant.
The second article entitled, “Music Effects on EEG in Intrusive and Withdrawn Mothers with Depressive Symptoms” found that rock music was generally beneficial to all its participants regardless of interaction type. This shows that rock music can be used as an energizing tool in depression and its symptoms. Both articles agree that preliminary studies such these needs to be confirmed and expanded on.
Both articles have deepened the author’s understanding on basic physiology and the need to understand it.
Conclusion
Music can serve humankind beyond social interaction and self expression. The two articles above shows that music works in deeper levels than one may initially think. It have come to this author’s attention how complex music is as a stimuli as it shows to activate receptors of both skin and auditory systems alike and affecting not only emotional areas of the brain but also areas responsible for language comprehension. It shows that it can be therapeutic and effective in reducing stress and depression. The ability of music stimuli to cause biochemicals such as dopamine, endocannabiniods naloxone supports this. It shows to play a promising role in the treatment of diseases both psychiatric and neurologic. Unfortunately, as both article mentions, there are limited scientific research on this.

Boso et al. (2006) discusses music stimuli and its neurobiological, neuropsychological, and neurophysiological pathways. This was done by discussing the neuroanatomy of the perceptual processing of music, the neuroanatomy of the emotional processing of music, the electrophysiological aspects of music processing, and the biochemical correlates of the musical experience.
Boso et al. presents many interesting points throughout the article. For instance, as they discuss the perceptual processing on music, they note that although music stimuli is normally processed like any other sound (via the auditory pathway), music vibrations also activate skin receptors. Another interesting fact is on how it notes that aside from the normal route of sound stimuli being collected from the outer ear and basically routed to the cochlea, to the auditory nerve, and, consequently, to the auditory thalamus and the auditory cortex, auditory projections are also routed to the amygdala and the medial orbitofrontal cortex, two areas of the brain that play a part in the processing of emotions. According to Carlson (2005), the amygdala is responsible for behavioral, automatic, and hormonal responses. The orbitofrontal cortex, located at base of the frontal lobe, receive and process various input from various regions of the brain including other regions of the frontal lobe. Its input is then dispensed to several areas including the cingulated gyrus, temporal cortex, and back to the amgdala thus affecting behavioral and physiological responses including emotional ones organized by the amygdala (Carlson, 2005). As this article continues to explain the emotional side of processing music, it cites a study conducted by Blood and Zatorre (2001) that discovered how the frontal lobes are activated when listening to pleasant music while the temporal lobes are activated during unpleasant music. Carlson (2005) notes that these two areas plays a role in speech and word recognition.
The article also discusses dopamine, endorphins, endocannabinoids, naloxone, and nitric oxide as biochemicals involved in the musical experience. “Dopamine, which is thought to play a crucial role in the response to naturally rewarding stimuli, may be involved in the enjoyment of music as well” (Boso et al., 2006).This may also be true for endorphins and endocannabiniods released into the bloodstream when listening to music. Naloxone may be responsible for the decrease of pleasant sensations brought about by listening to music. Lastly, nitric acid produces physical reactions by “inducing vasodilatation, warming of skin, and reduction of blood pressure valves” (Boso et al., 2006). The most fascinating fact regarding nitric acid is that it posses antibacterial, antiviral, and immunodulatory functions. The article then speculates if “listening to pleasant music could help to protect the organism against bacterial and viral infections, excessive immune and endothelial activation, as well as the detrimental effects of arterial hypertension” (Boso, et al., 2006).
Electroencephalography, otherwise known as EEG, has been a useful tool in measuring brain responses to music stimuli. Studies using the EEG, “left frontal asymmetry has been associated with positive affect or decreased negative in response to musical stimuli, whereas right frontal asymmestry has been associated with negative affect or decreased positive affect” (Boso et al, 2006). The article also mentions that when using the event related potential technique (ERP), unexpected words produces in a musical melody produces higher peek amplitudes than unexpected words spoken in a sentence. Event-related potentials allows for the separation of small potentials evoked by sensory stimuli from the larger voltage oscillations present in EEGs (Stefanatos & Osman, 2006). The ERP has proven useful in comparing language and music processing.
Carlson (2005) notes that there are two affective disorders that have depressive symptoms namely the bipolar disorder characterized by alternating periods of mania and depression and unipolar depression, a form of depression without the manic episodes. These conditions are particularly dangerous because individuals with this disorders often attempt to commit suicide. They can have very little energy, cry a lot, and unable to experience pleasure. Those with manic symptoms also have bouts of relentless energy and experience feelings of unjustifiable feelings of elation. Currently, these conditions are treated by medication. These medications include iproniazid, tricyclic antidepressants, and specific serotonin reuptake inhibitors. Electroconvulsice therapy (ECT) have also shown effective in the treatment of depression. An article by Tornik, Field, Hernandez-Reif, Diego, and Jones (2003) shows a promising and exciting alternative to the treatment of depression with the use of music as stimuli. In this experimental study where depressive mothers were asked to randomly listen to 20 minutes of either classical or rock music in an effort to understand the effects of music and emotion. This is a longitudinal study with 48 intrusive and withdrawn participating mothers who at the time had infants between the ages of three to six months of age. Intrusive mothers possessed behaviors such as “rough tickling, poking and tugging during interactions, using rapid, staccato movements, and showing tense and fake facial expressions (Torner et al., 2003). Withdrawn mothers demonstrated “flat affects, rare touching, rare vocalizing, disengaged behaviors, and looking away from the infant” (Torner et al., 2003). Power analysis shows that 48 participants for this study would yield an effect size of .40 with a .70 power (Although standard power level is of .80, it is the author’s opinion that the results in this study is quite compelling).
Participants were selected based on three screening measures. These measures include: (a.) Center for Epidemiological Studies-Depression Scale (CES-D), (b.) Intrusive/Withdrawn Interaction Style-Coding, and lastly,(c.) The Behavior Inhibition and Behavior Inhibition and Behavior Activation System Scale (BIS/BAS). The CES-D was used to determine depressive symptoms. The last two tools assessed interaction styles with the second one used as a confirmatory tool.
Actual experimental research was conducted one month after assessments. The women were randomly chosen to listen to 20 minutes of either rock or classical music. Three things were done before and after listening sessions: (a.) EEG was recorded three minutes before and after, (b) saliva samples were taken to measure cortisol levels, ( c.) mood and anxiety questionnaires were given ( questionnaire tools used were The Profile of Mood States-Depression Subscale (POMS) and The State Anxiety Inventory (STAI)).
Results show that all groups showed a decrease in depressive moods using the POM questionnaire tool yet only those intrusive-depressed mothers that listened to rock music showed a decrease in STAI anxiety score. Also, it is only this group of mothers that had significant decreased in cortisol levels shown in their saliva analysis.
As mentioned earlier, EEG is a useful tool in measuring brain responses to musical stimuli. Greater relative right frontal EEG activation is associated with the experience of negative emotions; left front EGG activation is associated with the experience of positive emotions. Yet, the authors on this article would like its readers to consider the corresponding EEG patterns under the broader categories of approach-avoidance emotions. This theory indicates that approach emotions such as joy, interest, and anger activate the left frontal regions and avoidance emotions such as distress and disgust activates the right frontal regions. Thus, if EEG were to measure brain activity before experimentation results would show that the mothers who were intrusive (approach) would exhibit left frontal EEG activation patterns, the mothers who were withdrawn (avoidance) would exhibit right frontal EEG activation.
The EEG for this study then yielded the following results. In general, The EEG showed greater relative right-frontal EEG activation (associated with feelings of distress and disgust) when listening for classical music and left-frontal EEG activation (associated with feelings of joy and interest) for rock music suggests a preference for rock music. “Although the intrusive group EEG values did not differ significantly across music types, the EEG for the withdrawn group suggested less negative (less right-frontal EEG) values for the rock than for the classical music.” (Boso et al., 2006). In conclusion, rock music elevated the moods of withdrawn depressive mothers as the study predicted but classical music did not show any benefit to the intrusive depressive group as originally theorized.
Potential Contributions and Author’s Areas of Learning
Music is something we often take for granted. It seems that instinctively it is understood by anyone and everyone. From its tempo, beat, and lyrics we naturally understand the meaning and the message that it seeks to convey. Music has always been a part of human existence. It is common understanding that different types, tempos, rhythms and such of music elicit different emotional responses within us. What is not common knowledge are the body’s physiological responses. In recent years, music has been an area of interest to be studied in a scientific approach in search of understanding its effects in clinical management in neurological and psychiatric disorders. Both articles mentioned above are such research. They believe that the understanding thereof can make significant contributions in clinical settings.
The first article, “Neurophysiology and Neurobiology of the Musical Experience” brings forth many interesting details such as how music stimuli are not only processed via normal auditory physiological pathways but also activates skin receptors. Another interesting detail presented in this article is how perceived pleasant musical stimuli activated frontal lobes as opposed to the temporal lobes activated by unpleasant.
The second article entitled, “Music Effects on EEG in Intrusive and Withdrawn Mothers with Depressive Symptoms” found that rock music was generally beneficial to all its participants regardless of interaction type. This shows that rock music can be used as an energizing tool in depression and its symptoms. Both articles agree that preliminary studies such these needs to be confirmed and expanded on.
Both articles have deepened the author’s understanding on basic physiology and the need to understand it.
Conclusion
Music can serve humankind beyond social interaction and self expression. The two articles above shows that music works in deeper levels than one may initially think. It have come to this author’s attention how complex music is as a stimuli as it shows to activate receptors of both skin and auditory systems alike and affecting not only emotional areas of the brain but also areas responsible for language comprehension. It shows that it can be therapeutic and effective in reducing stress and depression. The ability of music stimuli to cause biochemicals such as dopamine, endocannabiniods naloxone supports this. It shows to play a promising role in the treatment of diseases both psychiatric and neurologic. Unfortunately, as both article mentions, there are limited scientific research on this.
