The difference between Selfishness and Self-Centeredness.

In the 1960s, American neuroscientist Paul MacLean formulated the ‘Triune Brain’ model, which is based on the division of the human brain into three distinct regions. MacLean’s model suggests the human brain is organized into a hierarchy, which itself is based on an evolutionary view of brain development. The three regions are as follows:

1. Reptilian or Primal Brain (Basal Ganglia)
2. Paleomammalian or Emotional Brain (Limbic System)
3. Neomammalian or Rational Brain (Neocortex)

At the most basic level, the brainstem (Primal Brain) helps us identify familiar and unfamiliar things. Familiar things are usually seen as safe and preferable, while unfamiliar things are treated with suspicion until we have assessed them and the context in which they appear. For this reason, designers, advertisers, and anyone else involved in selling products tend to use familiarity as a means of evoking pleasant emotions.

Psychologists believe that the core issues of anorexia nervosa and bulimia nervosa are multifaceted, involving a combination of biological, psychological, and social factors. Here are some of the key issues:

Anorexia Nervosa

1. Distorted Body Image: Individuals with anorexia often have a distorted perception of their body size and shape, seeing themselves as overweight even when they are underweight.
2. Intense Fear of Gaining Weight: There is an overwhelming fear of gaining weight or becoming fat, which drives restrictive eating behaviors.
3. Control Issues: Anorexia can be a way for individuals to exert control over their lives, especially if they feel powerless in other areas.
4. Perfectionism: Many individuals with anorexia have perfectionistic tendencies, striving for an unattainable ideal of thinness.
5. Emotional Regulation: Restricting food intake can be a way to manage or numb difficult emotions and stress.

Bulimia Nervosa

1. Binge-Purge Cycle: Bulimia is characterized by cycles of binge eating followed by purging behaviors such as vomiting, excessive exercise, or misuse of laxatives.
2. Body Dissatisfaction: Similar to anorexia, individuals with bulimia often have a negative body image and are preoccupied with their weight and shape.
3. Impulsivity: Bulimia is often associated with impulsive behaviors and difficulties in regulating emotions.
4. Shame and Guilt: After binge eating, individuals with bulimia often feel intense shame and guilt, which perpetuates the cycle of purging3.
5. Co-occurring Mental Health Issues: Anxiety, depression, and other mental health disorders are commonly seen in individuals with bulimia.

Both disorders are complex and can have severe physical and psychological consequences. Treatment typically involves addressing these core issues through therapy, medical monitoring, nutritional counselling, and support groups.
