Self-Presentation: Self-Monitoring and Self-Handicapping

41.3K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Bulimia Nervosa01:30

Bulimia Nervosa

249
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Self-Discrepancy and Its Effects

42
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Self-Schemas

33.2K
In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Binge Eating Disorders01:23

Binge Eating Disorders

213
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Anorexia Nervosa01:28

Anorexia Nervosa

274
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects
Individuals with anorexia nervosa commonly exhibit extreme...

Area of Science:

  • Psychology
  • Neuroscience
  • Perceptual Science

Background:

  • Many individuals with eating disorders report a distorted perception of their body size, often feeling "fat."
  • Despite extensive research, empirical evidence confirming visual body size misperception in eating disorders remains elusive.
  • Understanding this phenomenon is crucial for advancing our knowledge of perceptual processing.

Purpose of the Study:

  • To highlight the significance of body size misperception in eating disorders for perceptual processing research.
  • To identify and discuss the experimental challenges in verifying body size misperception.
  • To propose methodological solutions to overcome these challenges and facilitate future research.

Main Methods:

  • Review of existing literature on body image perception and eating disorders.
  • Analysis of experimental design limitations in current research.
  • Conceptualization of novel experimental approaches to assess body size perception.

Main Results:

  • The study underscores the critical need to experimentally validate subjective claims of body size misperception.
  • Key challenges include controlling for confounding factors and developing objective measurement tools.
  • Proposed solutions focus on refined experimental paradigms and advanced neuroimaging techniques.

Conclusions:

  • Confirming body size misperception in eating disorders requires rigorous experimental investigation.
  • Overcoming methodological hurdles is essential for accurate understanding of perceptual distortions.
  • This research provides a framework for future studies aiming to elucidate the neurocognitive underpinnings of body image disturbances.
