Schizotypy, autobiographical memory, and theory of mind: sex differences.

Individuals with schizophrenia exhibit a range of cognitive impairments, including tasks assessing theory of mind (ToM) and autobiographical memory (AM). This study appears to be the first to examine how ToM and AM abilities interact in relation to schizotypy. Forty-seven undergraduate students reporting a wide continuous range of scores on the Schizotypal Personality Questionnaire (SPQ) completed a measure of ToM and a measure assessing various phenomenological qualities of AM.

Latent factor modeling of four schizotypy dimensions with theory of mind and empathy.

Preliminary evidence suggests that theory of mind and empathy relate differentially to factors of schizotypy. The current study assessed 686 undergraduate students and used structural equation modeling to examine links between a four-factor model of schizotypy with performance on measures of theory of mind (Reading the Mind in the Eyes Test [MIE]) and empathy (Interpersonal Reactivity Index [IRI]). Schizotypy was assessed using three self-report measures which were simultaneously entered into the model.

Social anxiety and social cognition: the influence of sex.

Current theoretical models predict a negative relationship between social anxiety and performance on measures of social cognition, yet there appears to be relatively little research that directly examines this relationship and the potential interaction of sex. Two samples of undergraduates self-reporting either a high (n=27; 59% female) or low (n=29; 62% female) level of social anxiety on the abbreviated Social Phobia and Anxiety Inventory completed two social cognition measures: the Reading the Mind in the Eyes Test (Eyes Test) and The Awareness of Social Inference Test-Parts 2 and 3). A multivariate analysis of variance revealed a significant group by sex interaction on overall social cognition performance.
