This study examined 'Theory of Mind' (ToM) functioning, its association with psychometric schizotypy and with self-reported psychotic-like experiences (PLEs) and depressive symptoms, in a community sample of adolescents. Seventy-two adolescents (mean age 14.51years) from Barcelona, Spain, completed questionnaires assessing PLEs, depressive symptoms, and schizotypy. A verbal ToM task and a vocab...

background & aim: co-morbidity with schizotypal personality in patients with obsessive-compulsive disorder (ocd) has been widely reported to be associated with poor treatment response. studies have repeatedly revealed a positive and a negative dimension for schizotypy. the primary aim of the present study was to explore if all or only certain features of schizotypy are predictive for therapy ou...

Compared to smokers in the general population, smokers with schizophrenia smoke more cigarettes per day and have higher nicotine dependence and biochemical indicators of nicotine intake. They also have more intense smoking topography and greater positive smoking expectancies. Little is known about the relationship between smoking and schizotypy, defined as the personality organization reflectin...

OBJECTIVE To examine the relationship between thought-action fusion (TAF) and schizotypy. METHOD In two separate samples of undergraduate students (Ns = 77 and 64), correlations were computed between a measure of TAF and indices of schizotypy and fantasy proneness. RESULTS Positive correlations were found between TAF and various aspects of schizotypy (i.e. perceptual aberration, magical ide...

Hallucinatory experiences are by far not limited to patients with clinical psychosis. A number of internal and external factors may bring about such experiences in healthy individuals, whereby the personality trait of (positive) schizotypy is a major mediator of individual differences. Psychotic experiences are defined as associating abnormal meaning to real but objectively irrelevant perceptio...

Positive and negative schizotypy may represent discrete factors or dimensions. To determine if distinct neurocognitive profiles are associated with these dimensions or factors, we classified university students on the basis of positive and negative schizotypal symptoms and conducted separate analyses. Following prior work in the neuropsychiatric literature, we predicted that subtle prefrontal d...

Attentional-interference using emotional Stroop tasks (ESTs) is greater among individuals in the general population with positive (versus negative) schizotypal traits; specifically in response to negatively (versus positively) valenced words, potentially capturing threat-sensitivity. Variability in attentional-interference as a function of subcategories of negatively valenced words (and in rela...

This research examined whether facets of schizotypy were differentially related to cognitive control and emotion-processing traits. In a confirmatory factor analysis (N = 261), a 3-factor model of schizotypy exhibited good fit and fit significantly better than a 2-factor model. In addition, only disorganized schizotypy was associated with poor cognitive control (specifically, prepotent inhibiti...

While schizotypal features are common during adolescence, they can also signal increased risk for the onset of schizophreniform disorders. Most studies with adolescents find that hallucination and delusion-like symptoms (positive schizotypal features) best predict future psychopathology. Still, the developmental process of positive schizotypy remains elusive, specifically with regards to 1) its...

BACKGROUND Schizotypy is a range of perceptual experiences and personality features related to risk and familial predisposition to psychosis. Despite evidence that schizotypy is related to psychosis vulnerability, very little is known about the expression of schizotypal traits in individuals with a psychotic disorder, and their relationship to clinical symptoms, cognition, and psychosocial func...
