BACKGROUND Schizophrenia is a mental disorder marked by an evolutionarily puzzling combination of high heritability, reduced reproductive success, and a remarkably stable prevalence. Recently, it has been proposed that sexual selection may be crucially involved in the evolution of schizophrenia. In the sexual selection model (SSM) of schizophrenia and schizotypy, schizophrenia represents the ne...

Positive implications of schizotypal personality have been discussed in the literature last few years, higher creativity being one them. Specifically, positive and negative schizotypy dimensions respectively related to lower levels. However, a considerable amount null associations between these two constructs also reported. This heterogeneity could be due multidimensionality both constructs. Th...

Individuals with schizophrenia fail to demonstrate a reduction in the P50 event-related potential (ERP) to the second of two identical auditory stimuli presented in close succession. This deficit could lead to sensory overload, cognitive disintegration and perhaps some of the symptoms of schizophrenia. However, evidence linking poor P50 suppression to symptoms in patients with schizophrenia has...

A large correlational study took a latent-variable approach to the generality of executive control by testing the individual-differences structure of executive-attention capabilities and assessing their prediction of schizotypy, a multidimensional construct (with negative, positive, disorganized, and paranoid factors) conveying risk for schizophrenia. Although schizophrenia is convincingly link...

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...

BACKGROUND AND OBJECTIVES Individuals who score high on positive schizotypy personality traits are vulnerable to more frequent trauma-related intrusive memories after a stressful event. This vulnerability may be the product of a low level of contextual integration of non-stressful material combined with a heightened sensitivity to a further reduction in contextual integration during a stressful...

We sought to validate the psychometric properties of a recently developed paradigm that aims to measure salience attribution processes proposed to contribute to positive psychotic symptoms, the Salience Attribution Test (SAT). The "aberrant salience" measure from the SAT showed good face validity in previous results, with elevated scores both in high-schizotypy individuals, and in patients with...
