It reviews the literature on perceptual-cognitive laterality effects in different sensory modalities, the lateralization of emotion and motor behavior, and the electrophysiological evidence. It also highlights some of the problems with the existing research and offers suggestions about the direction of future research. Organized into 17 chapters, this volume begins with an overview of cerebral asymmetry and the origins and mechanisms of lateralization. Then, it discusses the individual differences in laterality, methods and measurement used in laterality studies, and experiments on dichotic listening and auditory lateralization. The next chapters focus on the link between verbal laterality and handedness, tactual and perceptual laterality, asymmetry of motor performance, lateralization of emotional processes, and physiological measures of asymmetry. The book also introduces the handedness and its relation to cerebral function, genetics of laterality, development of cerebral lateralization, individual differences in cerebral organization, sex differences in laterality, reading- and language-related deficits, and control of the active hemisphere before concluding with a chapter discussing the experimental or strategy effects, the concept of complementary specialization, and the dichotomy between the two hemispheres of the brain. This book is a valuable resource for neuropsychologists, experimental psychologists, neurologists, and educators interested in understanding human brain function.
