Recent applications of the techniques and methodologies of cognitive psychology have had considerable implications for the study of brain function. Clinical observations concerning the fact that the disruption of specific cognitive tasks is critically dependent upon injury to particular areas of the brain have been backed up by evidence from information processing experiments with normal subjects. It is now clear that the time-honoured dichotomy between verbal and non-verbal skills has a real basis in terms of hemispheric specialization. In the majority of right-handed individuals, this latter-day phrenological analysis puts language-based skills in the left hemisphere and perceptually based skills in the right hemisphere. The verification of this dichotomy, which has been variously called digital versus analog or serial versus parallel processing or analytic versus wholistic analysis, is seen in the normal population by the application of two laboratory-based techniques.
