Hemispheric differences in memory search.

Abstract

Recent evidence suggests that memory demands contribute to visual field (VF) differences in tachistoscopic recognition. The present experiment examined VF differences in a memory-search paradigm using verbal stimuli (digits). The results demonstrated a significant advantage to right VF-left hemisphere presentation that was associated with the memory comparison stage of the task, but not with the perceptual encoding and response stages. These data are more consistent with a relative efficiency model of hemispheric specialization than with a functional localization model. © 1980.
