Abstract

Previous research (cf. Wickens, Mountford & Schreiner, 1981; Wickens & Sandry, 1982) has suggested that performance is facilitated by maintaining "integrity" between the hemisphere of information input, processing, and motor response. This task-hemispheric integrity has been found to exist during concurrent performance of verbal and spatial tasks, both of which are presented in a visual modality. The present study sought to examine whether task-hemispheric integrity exists during concurrent performance of a verbal and a spatial task when the verbal task is presented in an auditory modality and the spatial task(s) are presented in a visual modality. Fifty-six individuals (28M, 28F) performed an auditory dichotic listening task alone and concurrently with three spatial tasks, each loading on a different stage of information processing. The results indicate a differential effect of each of the spatial tasks on dichotic listening performance, with few reciprocal effects of the dichotic listening task on spatial task performance. Sex differences were also found on two of the spatial tasks. Potential theoretical and practical implications of the findings are discussed.
