Abstract
The hand preference of psychosis-prone college students was examined in two separate studies using the Annett Handedness Questionnaire. The first sample, subjects who completed the Perceptual Aberration and Magical Ideation scales ( n=895), confirmed Chapman and Chapman's (1987a) report of greater mixed handedness in psychosis-prone college students. The second sample, 214 college students who completed the Schizotypal Personality Questionnaire (SPQ), did not support Kim, Raine, Triphon and Green's (1992) findings of a correlation between mixed handedness and certain SPQ scales. The results of the current study are discussed in light of Overby's (1993) failure to replicate Chapman and Chapman's (1987a) study. The possible role of task conditions, skilled vs simple, in the emergence of atypical handedness in psychosis-prone college students is discussed.
