ABSTRACT
The hypotheses predicts altered hemispheric asymmetry in schizotypy have generated a tremendous amount of research. It now seems clear that there is a small but reliable relationship between schizotypy and mixed-hand preference. There has been a recent surge of interest in the genetics and ontogeny of handedness that may contribute to a similar understanding of the genetics and ontogeny of schizotypy and schizophrenia. Claridge book on schizotypy, Richardson, Mason, and Claridge cautiously concluded that schizotypy was associated with a reduced degree of lateralisation as reflected in hand preference and perceptual asymmetries. This chapter goal is to update their analysis by highlighting developments in author's understanding of hemispheric asymmetry, and in theoretical models that link it to schizophrenia and schizotypy. It concludes with the discussion of imaging methods that have been used primarily to study asymmetries in schizophrenia, but promise to further our understanding of hemispheric processing in schizotypy as well.
