Cognitive Dissonance01:38

Cognitive Dissonance

32.7K
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...

Positive Symptoms Schizophrenia: Hallucinations and Delusions

103
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

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.

Beck's Cognitive Therapy

80
Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.

Rational Emotive Behavior Therapy

81
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

Prismatic Beams: Problem Solving01:15

Prismatic Beams: Problem Solving

151
In the design of a supported timber beam subjected to a distributed load, both the beam's physical dimensions and the timber's characteristics, such as its grade and species, are critical. These factors determine the allowable stress values, which are crucial for calculating the necessary beam depth to ensure structural integrity and safety.
The design begins with analyzing the beam as a free body to identify moments and force balances, thereby determining support reactions. Next, the...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Psychiatry

Background:

  • Delusions in psychotic disorders are challenging to explain.
  • Predictive processing (PP) suggests the brain weighs prior beliefs against sensory data.
  • Psychosis is linked to altered prior belief weighting, creating a "delusion paradox".

Approach:

  • Review experimental evidence on low- and high-level processing in delusion-related phenotypes.
  • Link neurocognitive underpinnings to predicted processing within a hierarchical PP framework.
  • Examine the role of the prefrontal cortex in belief weighting.

Key Points:

  • Evidence shows decreased weighting of low-level priors and increased weighting of high-level priors in delusional individuals.
  • Hierarchical PP resolves the delusion paradox by compensating for low-level weighting deficits with high-level belief influence.
  • Delusional beliefs may sculpt perception and resist contradictory evidence due to this hierarchical weighting.

Conclusions:

  • A hierarchical predictive processing model resolves the "delusion paradox" in psychotic disorders.
  • This framework explains how delusions are maintained despite conflicting sensory information.
  • Understanding hierarchical belief weighting offers potential clinical implications for psychosis treatment.
