Neuropsychology qua interface.

This paper focuses on the multidisciplinary nature and requirements of neuropsychology. It illustrates two approaches to this convergence of neuropsychology and its complementary disciplines: the relationship between the dissociated visual-perceptual and spatial disorders consequent upon focal lesions of the right cerebral hemisphere in man and the evidence (neuroanatomical, neurophysiological, and behavioural) of two major cortico-cortical pathways for processing visual information in monkey; and the evolution of information-processing models (derived from cognitive psychology, linguistics, and pathophysiological data) to delineate the functional architecture of reading and speech production. It cites the study of attention and frontal-lobe function as a major target for research; and it invokes the need to encompass the art of medicine in neuropsychological research and practice.
