HANDEDNESS AND CEREBRAL HEMISPHERIC-DIFFERENCES IN MEMORY FOR PICTORIAL ORGANIZATION

Handedness and cerebral hemispheric differences were investigated with regard to the way pictorial information is stored in long-term memory . Left- and right-handed men were required to remember a series of pic torial scences that were organized or unorganized with respect to real -world configurations. Memory for these scences was measured with half -field presentations of detail probes and whole-scence probes. There w ere no differences between the two visual fields in latency. An Organi zation X Probe interaction was found for accuracy scores for positive responses in the right visual field but not the left visual field. Fur thermore, a three-way interaction (Organization X Probe X Visual Field ) was significant among right-handers but not among left-handers. Find ings are discussed in terms of hemispheric differences in long-term me mory and hemispheric specialization referring to handedness.
