Premonition is a feeling that something is about to happen when no normal information is available, and in which the target cannot be deduced from normally known data in the present. The main aim was to estimate the proportion of people who claim to have had various kinds of premonition experiences, and to explore any association between these experiences and personality variables such as neuro...

Schizotypal personality features and certain neurocognitive deficits have been shown to aggregate in the relatives of schizophrenic patients, supporting the view that both are likely to reflect genetic contributions to liability to schizophrenia. Within the relatives of schizophrenic patients, however, the interrelationships between these potential indicators of liability to schizophrenia are n...

In 2003, Gottesman and Gould advocated using the endophenotype concept in psychiatry genetics; describing it as a measurable component “along the pathway between disease and distal genotype” (p. 636). Especially in schizophrenia research, the idea of endophenotypes has gathered a wide following. Meehl’s definition of schizotaxia [Ref. (1), p. 829], as “an ‘integrative neural defect’ as the only...

Cannabis acutely increases schizotypy and chronic use is associated with elevated rates of psychosis. Creative individuals have higher levels of schizotypy, however links between cannabis use, schizotypy and creativity have not been investigated. We investigated the effects of cannabis smoked naturalistically on schizotypy and divergent thinking, a measure of creativity. One hundred and sixty c...

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...

INTRODUCTION In clinical high-risk populations, category fluency deficits are associated with conversion to psychosis. However, their utility as clinical risk markers is unclear in psychometric schizotypy, a group experiencing schizophrenia-like traits that is at putative high risk for psychosis. METHODS We examined whether introducing affective or cognitive load, two important stress vulnera...

Schizotypy provides a useful construct for understanding the development of schizophrenia spectrum disorders. As research on the epidemiology of psychotic symptoms and clinical risk for psychosis has expanded, conceptual challenges have emerged to comprehend the nature and borders of the space comprised between personality variation and psychosis. Schizotypy is considered in light of these more...

The concept of schizotypy or "psychosis proneness" captures individual differences in perceptual, cognitive, and affective experiences that may relate to a range of psychotic disorders. The concept is an important way to assess the contribution of pre-existing psychological and genetically based biological features to the development of illnesses such as schizophrenia (so called endophenotypes)...

BACKGROUND An association between white noise speech illusion and psychotic symptoms has been reported in patients and their relatives. This supports the theory that bottom-up and top-down perceptual processes are involved in the mechanisms underlying perceptual abnormalities. However, findings in nonclinical populations have been conflicting. OBJECTIVES The aim of this study was to examine t...
