Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

519
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

Personality Disorders: Dependent and Obsessive-Compulsive

387
Dependent personality disorder and obsessive-compulsive personality disorder are two separate psychological conditions that influence behavior, relationships, and overall life functioning. Though both involve maladaptive behaviors, their core characteristics and motivations differ significantly.
 Dependent Personality Disorder
Dependent personality disorder is characterized by an excessive reliance on others to manage various aspects of life. Individuals with this disorder often struggle...

Reason and Intuition

7.4K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Borderline Personality Disorder01:25

Borderline Personality Disorder

535
Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Anxiety: Overview

927
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

787
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Area of Science:

  • Psychology
  • Neuroscience
  • Behavioral Economics

Background:

  • Compulsive buying (CB) is a disorder characterized by persistent urges to buy.
  • Understanding the cognitive underpinnings of CB is crucial for developing effective interventions.

Purpose of the Study:

  • To investigate impulsivity and compulsivity in individuals with and without compulsive buying.
  • To examine cognitive functions such as response inhibition, delay discounting, and selective attention in relation to compulsive buying behavior.

Main Methods:

  • 120 undergraduate students were assessed using questionnaires for impulsivity (Barratt Impulsiveness Scale) and compulsivity (Yale-Brown Obsessive-Compulsive Scale).
  • Cognitive tasks included delay discounting (EDT), response inhibition (Go/No-Go), and selective attention (Dot-Probe).
  • A simulated online shopping experiment was conducted with 40 participants.

Main Results:

  • Individuals with compulsive buying exhibited higher impulsivity and compulsivity.
  • Impaired response inhibition was observed in compulsive buyers during the Go/No-Go task.
  • Compulsive buyers were quicker to add items to a cart and spent more money in a simulated shopping task.
  • Impulsivity significantly contributed to the variance in compulsive buying scores.

Conclusions:

  • Compulsive buying is associated with subtle impairments in cognitive functions, particularly response inhibition under cognitive load.
  • The findings suggest that impulsivity plays a key role in the manifestation of compulsive buying.
  • Simulated real-life shopping scenarios can effectively reveal cognitive deficits associated with compulsive buying.
