Anorexia Nervosa01:28

Anorexia Nervosa

2.0K
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.

Bulimia Nervosa

1.1K
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 Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Binge Eating Disorders

827
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...

Self-Schemas02:16

Self-Schemas

24.8K
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.

Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

419
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Summary

Self-focused attention (SFA) was lowest in women with current anorexia nervosa (AN), contrary to expectations. Body image concerns and executive function deficits may influence SFA levels in AN.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Psychology

Background:

  • Anorexia nervosa (AN) involves preoccupation with body experience, shape, and weight gain, suggesting intense self-focused attention (SFA).
  • Previous research has not characterized SFA or its neurocognitive underpinnings in AN.

Purpose of the Study:

  • To investigate self-focused attention (SFA) in women with current anorexia nervosa (AN-C), a history of AN (weight-restored, WR), and healthy controls.
  • To examine the relationship between SFA, body image disturbance, and executive functioning in these groups.

Main Methods:

  • Cross-sectional study comparing AN-C (n=24), WR (n=19), and healthy controls (n=24).
  • Assessment of private and public SFA, body image concerns, and executive functioning, including perseverative errors.

Main Results:

  • Self-focused attention (SFA) was lowest in the current AN group (AN-C) and highest in the weight-restored group (WR).
  • Shape concerns were negatively correlated with SFA, particularly in the AN-C group, even after controlling for depression and social anxiety.
  • Perseverative errors in executive attention were associated with lower public SFA in the AN-C group.

Conclusions:

  • The acute state of AN may paradoxically reduce pathological self-focus, potentially reinforcing symptoms.
  • Body image concerns might divert attention from general SFA in individuals with AN.
  • Executive attention deficits, specifically perseverative errors, may underlie the observed patterns of SFA in current anorexia nervosa.
