Summary
Self-reported thought disorder (TD) in individuals with mild psychosis symptoms correlates with disorganized thinking and cognitive impairments. This study highlights the continuous nature of subjective TD and its link to semantic and executive functions.
Area of Science:
- Cognitive Psychology
- Psychiatry
- Neuroscience
Background:
- Objective thought disorder (TD) varies continuously and impacts cognition in psychosis.
- Subjective TD measures exist but their relation to objective TD and cognition is unclear.
Purpose of the Study:
- To assess the correspondence between self-reported TD and schizotypal disorganization.
- To explore the association between subjective TD severity and cognitive performance.
Main Methods:
- Data from 33 healthy individuals and 38 patients with schizophrenia/schizoaffective disorder (mild symptoms) were pooled.
- Self-report questionnaires for TD and schizotypal disorganization were administered.
- Cognitive functions, including semantic and executive abilities, were assessed.
Main Results:
- Self-reported TD frequencies correlated with schizotypal disorganization.
- Subjective TD showed associations with semantic and executive functioning.
- Mild subjective TD demonstrated continuous variation, aligning with the continuum model.
Conclusions:
- Self-reported subjective TD is linked to disorganized experiences and cognitive alterations at mild severity.
- Subjective TD measures offer valuable insights into the continuum of thought disorder.
- Findings support the continuum model of psychosis, extending to subjective experiences and cognition.

01:30Negative and Cognitive Symptoms of Schizophrenia
319
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,...

269
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.

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.

610
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

01:25Cognitive Therapy
705
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...
