Sažetak
Based on a critical literature review, this study re-examines the claim that mixed-handedness might be a presumed neurodevelopmental marker of both schizophrenia and schizotypy. Handedness was assessed with a standardized handedness questionnaire and schizotypy with the SPQ in a large community sample, in a “ highly healthy” sample, in siblings of schizophrenia, and in patients with schizophrenia. The results did not show a specific relationship between mixed-handedness and features of schizotypy. Only the cognitive-disorganization factor of the SPQ was related to a higher incidence of mixed-handedness, significantly in patients with schizophrenia and as a statistical trend in siblings of patients with schizophrenia. These findings add to the inconsistent observations on reduced laterality along the schizophrenia spectrum, supporting previous notions “ Re-examining handedness in schizophrenia: now you see it-now you don't” (Nelson et al., 1993).
