Affective dysfunction is a defining schizotypy feature; yet the majority of studies examining affective dysfunction have largely relied on self-report of trait affect, which reflects only one dimension of emotional experience. Emerging research has explored a second dimension, state affect, using laboratory manipulation, with most finding that schizotypal participants report experiencing less p...

This article reports on the development of a new self-report questionnaire measure of schizotypy - the Multidimensional Schizotypy Scale (MSS). Schizotypy offers a useful and unifying construct for understanding schizophrenia-spectrum psychopathology. Questionnaire measures have been widely used to assess schizotypy and have greatly informed our understanding of the construct. However, availabl...

Paranoia is a dimension of clinical and subclinical experiences in which others are believed to have harmful intentions. Mild paranoid concerns are relatively common in the general population, and more clinically severe paranoia shares features with social anxiety and is a key characteristic of schizotypy. Given that subclinical manifestations of schizotypy and paranoia may predict the occurren...

Negative schizotypal traits may be related to anhedonia and/or amotivation; however it is unclear which of these symptoms is related to negative schizotypy to a greater extent. Moreover, the impact of schizotypal traits on overall subjective well-being remains uncertain. The present study examined these two questions in a non-clinical sample assessed for schizotypal traits (n = 138). Schizotypa...

It was examined whether psychotic-like personality traits in a sample of 205 college students could predict logical reasoning deficits, akin to those seen in schizophrenia. The participants were tested on their ability to assess the logical validity of premises (Logical Reasoning Task), and completed a multi-dimensional schizotypy inventory (O-LIFE). Low accuracy was associated with increased l...

Patients with schizophrenia often exhibit structural brain abnormalities, as well as neurological soft signs (NSS), consistent with its conceptualization as a neurodevelopmental disorder. NSS are mild, presumably nonlocalizing, neurological impairments that are inferred from performance deficits in domains such as sensory integration, motor coordination, and motor sequencing. The vulnerability ...

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...

Ideas of reference are considered hallmarks of schizophrenia-related psychopathology. However, the specificity of referential thinking to schizophrenia-related psychopathology has not been examined empirically. Schizotypy reflects the latent liability for schizophrenia and is associated with referential thinking. Referential thinking may occur in other forms of psychopatholoy, such as social an...

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...
