This study employed global/local stimuli to investigate RT performance of normal controls on divided and directed attention tasks. The purpose of the present study was two-fold: (1) to examine the role of attentional factors in global versus local processing, and (2) to investigate hemispheric differences in hierarchical visual processing. The results indicated that response times were significantly faster under the directed attention condition compared to the divided attention condition. The data, however, failed to support the hypothesized left hemisphere/analytic and right hemisphere/holistic dichotomy that predicts hemispheric superiority in local versus global processing. Evidence from the present investigation is consistent with the claim that global/local processing is mediated by attentional mechanisms and not solely dependent on lower-level sensory processes. Furthermore, the data suggest that attentional mechanisms involved in global/local analysis are not lateralized and that both hemispheres are equally proficient at allocating attentional resources to global and local levels.Dept. of Psychology.
