| Abstract | Retrieval of memories is enhanced when bilateral saccades are made immediately before attempting retrieval. One hypothesis is that saccades enhance retrieval by increasing interaction of the brain hemispheres. To test this, subjects viewed arrays of lateralized letters and indicated whether target letters matched either of two probe letters. Matching targets and probes were presented to either the same hemisphere (within-hemisphere trials) or separate hemispheres (across-hemisphere trials). Match detection requires interhemispheric interaction on across-hemisphere trials but primarily intrahemispheric processing on within-hemisphere trials. Subjects performed letter matching following saccades and a fixation control condition. Saccades increased match-detection accuracy on within-hemisphere trials only, suggesting that, counter to the hypothesis, saccades enhance intrahemispheric processing but not interhemispheric interaction. Across-hemisphere accuracy was higher, however, for subjects who were not strongly right-handed, versus those who were, and the absence of strong right-handedness may reflect greater interhemispheric interaction. We discuss implications for accounts of saccade-induced retrieval enhancement. (Contains 4 figures.) (As Provided). |
