Schizotypal personality can be perceived as a personality trait and considered as a dimension. In recent decades, this way of thinking has been promoted by a British psychologist Gordon Claridge, the main author of the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) schizotypy scale, which is the subject of this article. In such dimensional model, schizotypy represents a continu...

Studies have found that shamanic practices are associated with statistically significant reductions in mood disturbance relative to baseline. However, contrary results were obtained for non-shamanic practitioners exposed to shamanic-like techniques. These inconsistent results may be partially due to a personality trait referred to as schizotypy, which has been demonstrated to influence suscepti...

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...

OBJECTIVE The present study introduced a novel word-detection paradigm to examine detection biases as a function of different schizotypy dimensions in a sample of undergraduate students. METHOD The participants (N = 80) were asked to detect fast moving (8 frames/second) words among simultaneously moving non-words. RESULTS Positive schizotypy was associated with a tendency to report words th...

The Schizotypal Ambivalence Scale (SAS) is a 19-item revision of the Intense Ambivalence Scale, which was designed to identify ambivalence described by Meehl as characteristic of schizotypy and schizophrenia. The present study examined the psychometric properties of the SAS in a sample of 997 college students. The study also provided preliminary evidence regarding the concurrent validity of the...

The Wisconsin Schizotypy Scales are widely used for assessing schizotypy in nonclinical and clinical samples. However, they were developed using classical test theory (CTT) and have not had their psychometric properties examined with more sophisticated measurement models. The present study employed item response theory (IRT) as well as traditional CTT to examine psychometric properties of four ...

The authors examined whether three indicators of Schizotypy, the Revised Social Anhedonia Scale (RSAS), Magical Ideation Scale (MIS), and Perceptual Aberration Scale (PAS), identify a common latent class or taxon as conceptualized by P. E. Meehl (1962, 1990). The separate and joint latent structures of these scales were evaluated using taxometric methods in two large, independent samples. Repli...

INTRODUCTION Stereotype awareness--or an individual's perception of the degree to which negative beliefs or stereotypes are held by the public--is an important factor mediating public stigma, self-stigma and their negative consequences. Research is required to assess how individuals become more sensitive to perceive stereotypes, pointing the way to therapeutic options to reduce its negative eff...

Previous research has shown a robust association between schizotypy and mixed/ambiguous-handedness, but little is known about the universality of this relationship outside Western cultures. The present paper examines this issue in a sample of 413 Japanese students administered (in Japan) the Annett handedness questionnaire and a schizotypy scale (STA). Conventional analyses of current hand pref...
