Abstract

The present study used a divided visual field (DVF) paradigm to investigate possible hemispheric asymmetries in delayed recognition memory for lists of words and drawings. The influence of sex and certain stimulus characteristics (i.e., abstract vs. concrete words and drawings) on these lateralization effects were also examined. Forty-four right-handed participants with no history of neurological problems were asked to recognize lists of words and designs initially presented to the left or right visual field using a tachistoscope. A non-parametric measure of recognition discriminability was used as the dependent measure. 2 x 2 x 2 mixed factorial ANOVAs were conducted on these discriminability scores for both drawings and words to assess the effects of visual field of presentation, stimulus type, and sex. These ANOVAs revealed no significant effects of sex or visual field for either words or drawings. Significant effects of stimulus type (abstract vs. concrete) were observed for both drawings and words, as well as a significant interaction between visual field and word type. These findings are discussed in terms of the possible lateralization of memory processing in the two hemispheres and the dual-coding hypothesis of memory encoding (Paivio, 1990).Dept. of Psychology.
