Cerebral asymmetry and the psychophysiology of attention.

The literature relevant to psychophysiological aspects of the lateralized control of attention is reviewed. It is argued that the description of attention as a dynamic process tends to obscure examination of the structural determinants of attentional asymmetries. Psychophysiological evidence suggests that a right hemispheric predominance in attention is quite possibly the natural outcome of a similar asymmetry in activational, interoceptive and early visual processes.
