Clinical and phenomenological accounts of schizophrenia suggest that impairments in self-reflective processes significantly contribute to psychopathological expression. Recent imaging studies observe atypical cerebral activation patterns during self-reflection, especially around the cortical midline structures, both in psychosis-prone adults and individuals with schizophrenia. Given that self-reflection processes consolidate during adolescence, and that early transient expression of psychosis (positive schizotypy) also arises during this period, the present study sought to examine whether atypical cerebral activation during self-reflection task could be associated with early schizotypic expression during adolescence. Forty-two neurotypical adolescent participants (19 females) aged from 12 to 19 (15.92±1.9) underwent a self-reflection task using functional neuroimaging (fMRI), where they had to evaluate trait adjectives (1 to 4 ratings) about themselves or their same sex best friend. The Schizotypal Personality Questionnaire (SPQ) was employed to assess positive schizotypic expression. Results showed that positive schizotypy in adolescents significantly correlated with cortical midline activation patterns in the dorsomedial prefrontal cortex (dmPFC) and the posterior cingulate cortex (PCC), as well as the dorsolateral PFC and the lingual gyrus. The results are consistent with previous imaging literature on self-reflection and schizophrenia. They further highlight that the relationship between self-reflection processes and positive schizotypy operates at the trait level of expression and can be observed as early as adolescence.

There has been a recent surge in schizotypy and metacognition research. Metacognition is an umbrella term for higher-order thought processes. Here, we focussed on maladaptive metacognitive beliefs, which are beliefs related to one's thought processes and often play an important role in the preponderance of psychological disorders.

Background: Recent research shows that individuals exhibiting schizotypal traits (ST) are more prone to developing other psychiatric disorders such as anxiety and depression. Regarding the relationship between empathy and schizotypy, a considerable degree of heterogeneity has been observed. The objective of this study was to describe the presence of ST in college students and the relationships among ST, psychiatric symptoms, and empathy.

Social cognition may play a central role in many schizotypal personality characteristics, such as suspiciousness, constricted affect, social anxiety, and lack of close relationships. This study investigated how factors relevant to self-other distinction (i.e.

Introduction: Evidence highlights the importance of social isolation as a critical yet underserved treatment target for individuals managing psychosis. Schizotypal traits represent a useful model of psychosis, facilitating the assessment of contributors to social isolation without the confounds associated with schizophrenia. This study utilised structural equation modelling to examine the unique predictive capacity of schizotypal traits for subjective and objective indices of social isolation.
