ABSTRACT
In recent years, one of the areas studied most widely in a variety of psychological and neurological subspecialties has been the lateralization of functioning and hemispheric specialization. The advent of a surgical procedure to control epileptic seizures by severing the connections between the cortical hemispheres made it possible to study functioning in individuals with split brains. The results from these studies captured the imagination of scientists and laymen alike and suggested a degree of hemispheric differentiation and indeed of cognitive differentiation in functioning never before anticipated.
