Positive schizotypy is linked to over-attributing intentions and faster context processing, independent of broader context processing deficits. These factors may contribute to positive psychotic symptoms.
Area of Science:
- Psychology
- Psychiatry
- Cognitive Neuroscience
Background:
- Impaired Theory of Mind (TOM) is linked to schizophrenia and schizotypy.
- Over-attributing intentions (intentionality bias) correlates with positive psychotic symptoms.
- This bias may stem from deficits in context processing (CP).
Purpose of the Study:
- To examine the relationship between positive schizotypy and both intention over-attribution and context processing.
- To determine if context processing deficits explain the link between intentionality bias and positive schizotypy.
Main Methods:
- 119 healthy individuals participated.
- Assessed using the Schizotypal Personality Questionnaire.
- Utilized tasks measuring contextual processing and Theory of Mind (TOM).
Main Results:
- Positive schizotypy correlated with over-attributing intentions and faster implicit context processing.
- Context processing deficits did not explain the intentionality bias-schizotypy association.
- Both intention over-attribution and faster context processing predicted positive schizotypy.
Conclusions:
- Over-attribution of intention is distinct from broader context processing deficits.
- Both factors may independently contribute to the development and maintenance of positive psychotic symptoms.
