Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Intrinsically Disordered Proteins

19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Cable Subjected to Its Own Weight

804
Overhead power transmission lines rely on cables to carry electricity across large distances. To ensure the stability and functionality of these lines, it is crucial to understand the shape and tension experienced by the cables under the influence of their weight.
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...

Language and Cognition

807
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitive Therapy01:25

Cognitive Therapy

1.1K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Cognition and Behavior

383
Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

Summary
This summary is machine-generated.

Adults with hoarding disorder (HD) experience significant subjective cognitive impairments, particularly in memory and attention. These deficits are linked to hoarding severity and the motivation to save items to prevent forgetting.

Area of Science:

  • Psychiatry
  • Neuropsychology
  • Cognitive Science

Background:

  • Hoarding disorder (HD) is a complex condition characterized by persistent difficulty discarding possessions.
  • Subjective cognitive impairment is increasingly recognized as a potential factor in HD.
  • Understanding cognitive deficits is crucial for developing effective interventions for HD.

Purpose of the Study:

  • To investigate subjective cognitive impairment in adult patients diagnosed with hoarding disorder.
  • To explore the relationship between cognitive functioning, hoarding severity, and motivations for saving behavior.
  • To examine the influence of comorbid symptoms on cognitive impairment in HD.

Main Methods:

  • Eighty-three adult patients with hoarding disorder (HD) and 46 healthy controls (HC) participated.
  • Participants completed diagnostic interviews and self-report measures assessing cognitive function, saving motivations, hoarding severity, depression, anxiety, stress, and obsessive-compulsive disorder (OCD) symptoms.
  • Statistical analyses were used to compare groups and examine correlations between variables.

Main Results:

  • Patients with HD reported significantly greater subjective cognitive impairment compared to HC participants across multiple domains, including memory, attention, and distractibility.
  • These cognitive differences persisted even after controlling for comorbid psychiatric symptoms.
  • In the HD group, subjective cognitive impairment was correlated with hoarding severity and specifically with the motivation to save items to avoid forgetting, independent of comorbidities.

Conclusions:

  • Subjective cognitive impairments, especially in memory and attention, are prevalent in hoarding disorder.
  • These cognitive deficits are associated with core features of HD, including saving behaviors and motivations.
  • Findings support behavioral models of HD emphasizing decision-making deficits and highlight the need to address cognitive functioning in treatment.
