Beck's Cognitive Therapy01:25

Beck's Cognitive Therapy

528
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.

Self-Schemas

36.5K
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.

Cognitive Dissonance01:38

Cognitive Dissonance

37.9K
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...

Negative and Cognitive Symptoms of Schizophrenia

989
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

The Influence of Cognition on Affect

276
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

1.0K
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

Summary

Our body representation is not always accurate, even in healthy individuals. Research shows systematic distortions in how we perceive body space, touch, and position are common in normal cognition.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Psychiatry

Background:

  • Pathological body misperceptions are common in neurological and psychiatric disorders.
  • Ordinary body experience feels immediate and accurate, masking underlying representational distortions.

Discussion:

  • Investigates systematic distortions in body representation within healthy cognition.
  • Focuses on distortions in tactile distance perception and position sense.
  • Explores distortions in higher-order representations like the conscious body image.

Key Insights:

  • Large, systematic distortions of body representation are a normal aspect of healthy cognition.
  • These distortions affect fundamental aspects of bodily experience, including touch and proprioception.
  • Evidence suggests distortions extend to conscious body image.

Outlook:

  • Discusses the potential relationships between different body representations.
  • Examines the implications of these findings for understanding both normal and abnormal body perception.
  • Highlights the need for further research into the mechanisms and functions of body representation distortions.
