The main objective of this ex post facto study is to compare the differences in cognitive functions and their relation to schizotypal personality traits between a group of unaffected parents of schizophrenic patients and a control group. A total of 52 unaffected biological parents of schizophrenic patients and 52 unaffected parents of unaffected subjects were assessed in measures of attention (...

The Rust Inventory of Schizotypal Cognitions (RISC) is a new, psychometrically constructed, short questionnaire for assessing the schizotypal cognitions associated with the positive symptoms of acute schizophrenia. It differs from previous scales in having been developed and standardized with special attention to normal distribution in the general population, and in emphasizing cognitive conten...

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...

Contagious yawning is a common, but poorly understood phenomenon. We hypothesized that contagious yawning is part of a more general phenomenon known as mental state attribution (i.e. the ability to inferentially model the mental states of others). To test this hypothesis we compared susceptibility to contagiously yawn with performance on a self-face recognition task, several theory of mind stor...

Having shown taxometrically that there exists a hypohedonic schizotypal taxon in a college population, J. J. Blanchard, S. W. Gangestad, S. A. Brown, and W. P. Horan (2000) suggested that P. E. Meehl erred in revising his 1962 theory by postulating a normal-range individual differences variable of hedonic capacity that potentiates schizotypy into schizophrenia. The aversive drift and secondary ...
