Using a nonclinical, noncollege sample, this study set out to confirm and extend previous findings of a relationship between the cognitive-perceptual features of schizotypal personality and mixed handedness using the Schizotypal Personality Questionnaire (SPQ). Based on previous findings of relationships between nondextrality and thought disorder in schizophrenia, it was predicted that the odd speech subscale of the SPQ would have the strongest relationship with mixed handedness. Mixed-handed adults did have significantly higher scores than right-handed and left-handed adults on the cognitive-perceptual factor and its subscale of odd speech. Similar trends were also observed for the cognitive-perceptual subscales of suspiciousness, eccentric behavior, and unusual perceptual experiences. These results support and extend previous findings, and are broadly consistent with the association between thought disorder and nondextrality in schizophrenia.
