Novel metaphor processing in high and low schizotypal individuals

This study investigated whether non-clinical high-schizotypal adults exhibit pragmatic language impairments like those observed in schizophrenia patients. 664 participants completed a novel metaphor comprehension task designed to assess three types of interpretations: figurative, literal, and concrete, alongside the Schizotypal Personality Questionnaire (SPQ). Findings reveal that individuals with high SPQ scores show significant difficulties in understanding metaphors, aligning with patterns seen in schizophrenia. Errors predominantly favored literal and concrete interpretations. The study emphasizes the importance of utilizing novel metaphors to measure the ability to process figurative language, as lexicalized metaphors may only reflect associative thinking rather than true comprehension.
