Schizotypy is phenotypically associated with neuroticism. To reveal the origin of this association, we assessed 3,349 (1,449 monozygotic, 1,105 dizygotic [DZ] same-sex and 795 DZ opposite-sex) twins on a 12-item version of Chapman's Psychosis-Proneness Scales and the short form of the Eysenck Personality Questionnaire-Revised as measures of schizotypy and neuroticism. A substantial proportion (...

BACKGROUND The psychosis phenotype is distributed along a severity continuum that ranges from psychological well-being to full-blown psychosis. Schizotypal traits and psychotic-like experiences are considered as one of the possible phenotypic indicators of the latent liability for psychosis (named schizotypy). This selective review offers a general overview and update of trait schizotypy and ps...

Semantic processing deficits are present in schizophrenia and are particularly evident on semantic priming tasks. Using high schizotypes (psychosis-prone individuals) can overcome some confounds involved in studying actively symptomatic schizophrenics. In the current study, 26 high and 32 low scorers on the O-LIFE schizotypy scale (from a sample of 251 students) were selected for testing. All s...

Schizotypal personality is characterized by a variety of traits, such as magical thinking, unusual perceptual experiences, and anhedonia. Factor analytic studies have shown that these characteristics tend to cluster into at least two separate dimensions (positive and negative schizotypy). Schizotypy is associated with vulnerability to schizophrenia. However, it is also related to higher scores ...

Schizophrenia is a common psychiatric diagnosis affecting approximately 0.7% of the population worldwide (1). Cognitive symptoms in schizophrenia, such as impaired memory, poor attention/information processing, and difficulties with executive functions, are a core feature of schizophrenia and strongly related to quality of life and functional outcomes, yet generally respond poorly to current tr...

Introduction Schizotypy is conceptualized to be on the continuum of risk for psychosis. However, previous studies that used dimensional approach schizotypy failed confirm expected relations between schizotypal traits and polygenic scores (PRS) schizophrenia. A taxonic an alternative way looking at schizotypy, but best our knowledge it has not been explore genetic architecture this construct. Ob...

INTRODUCTION Odd speech is prevalent in individuals with schizotypy compared to controls and this odd speech is particularly pronounced under stress-induced conditions. Despite a number of research studies that have examined odd speech, the mechanisms underlying this phenomenon remain unclear. There is reason to suspect that the increase in odd speech observed in schizotypy may reflect atypical...

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...

The aim of this study was to examine the differences in manifestations three schizotypal dimensions (cognitive-perceptive, interpersonal, disorganized), depending on attachment style and exposure different adverse experiences during childhood. conducted 181 participants, with a mean age 20.09 years (SD = 2.19). Schizotypy measured using Schizotypal Personality Questionnaire - Brief Revised (SPQ...

Intrusive mental experiences occur within posttraumatic stress disorder (PTSD) and some psychotic disorders. Similarities in the phenomenology and content in the intrusions of both disorders have been noted. Currently there is little understanding of any common etiology in terms of information-processing styles. This study investigated predictors of analogue posttraumatic intrusive cognitions w...
