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...
BACKGROUND Schizotypal traits in adolescents from the general population represent the behavioral expression of liability for psychotic disorders. Schizotypy assessment in this sector of population has advanced considerably in the last few years; however, it is necessary to incorporate recent advances in psychological and educational measurement. OBJECTIVE The main goal of this study was to d...
Abstract The aim of this study was to better understand the relation schizotypy traits with sensory gating ability in a sample community-dwelling individuals high and low traits. Sensory assessed through paired click paradigm mid-latency evoked responses (i.e., P50, N100, P200), while were SPQ-BR which used classify participants into “high” “low” groups. Based on prior work, we hypothesized tha...
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...
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...
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 ...
Schizotypy refers to a constellation of personality traits that are believed to mirror the subclinical expression of schizophrenia in the general population. Evidence from pharmacological studies indicates that dopamine (DA) is involved in the etiology of schizophrenia. Based on the assumption of a continuum between schizophrenia and schizotypy, researchers have begun investigating the associat...
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...
There is increasing empirical evidence from factor analytical studies that schizotypy is composed of three dimensions. All studies into the multidimensionality of schizotypy used common factor analysis of scales, either exploratory or confirmatory. We argue that for research into the multidimensionality of schizotypy with dichotomous item responses on questionnaires (as with the Schizotypal Per...
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...
