Individual Differences in Hemispheric Specialization

This volume originates from a NATO Advanced Research Workshop held in Maratea. Italy from 8th-15th October 198~. Aims and contributions are described at greater length in the Introduction and the following chapters. It is hoped that this volume will provide a critical overview of hemispheric specialization in relation to individual differences, but one that is not intended to be comprehensive. Three contributions on this theme are made by authors who were invited to the Workshop but were unable to participate in it. The volume contains a critical appraisal of the differentially specialized functions of left and right human cerebral hemispheres in verbal and visuospatial domains respectively (formerly cerebral dominance). in relation to individual variation due. for example. to gender and handedness. Critical cross-comparison of several methods of assessing hemispheric specialization such as perceptual/behavioral. clinical/neurological. electrophysiological and "real time" methods of assessment of cerebral orientation have been made. Individual differences have been considered in relation to statistical concepts in the assessment of cerebral lateralization. Some emphasis has been placed on the application of these methods and concepts to psychopathology.
