“…The results suggest that the memory traces left by laterally presented stimuli are more easily accessible in the contralateral hemisphere, which suggests a contralateral organization of visual memories. than when they are presented in opposite hemifields (Banich & Shenker, 1994a;Berrini, Capitani, Della Sala, & Spinnler, 1984;Dimond, Gibson, & Gazzaniga, 1972;Kleinman & Little, 1973;Leiber, 1982;Lordahl et al, 1965). These findings, however, are not conclusive because of a common methodological issue.…”

“…First, retrieval was facilitated if the stimuli were presented again in the same hemifield (and therefore to the same hemisphere) in which they were presented the first time (Experiments 1-3). While a same-hemifield advantage had already been claimed in previous research (Banich Volume 9, Number I & Shenker, 1994a; Lordahl et al, 1965), earlier studies confounded the same-hemifield condition with a samelocation condition. The experimental procedures employed in the present studies control for the samelocation confound.…”

This study investigates the hemispheric organization of visual memories. In five experiments, we examine the processes associated with the recognition of line patterns that are flashed laterally during a study phase. The first three experiments demonstrate a recognition advantage for patterns presented at test in the same (rather than in the opposite) hemifield in which they were presented during a previous study phase. This difference was obtained even when stimuli were presented in different locations within the same hemifield. Experiment shows that patterns presented centrally during the recognition phase elicit ERPs that are systematically more negative over the hemisphere contralateral to the side at which they were presented during the study phase. In Experiment 5, however, we found that subjects were unable to indicate the side of initial presentation of the patterns. The results suggest that the memory traces left by laterally presented stimuli are more easily accessible in the contralateral hemisphere, which suggests a contralateral organization of visual memories.
