Visual paired comparison performance is impaired in a patient with selective hippocampal lesions and relatively intact item recognition
In this study, we have examined visual recognition memory in a patient, YR, with discrete hippocampal damage who has shown normal or nearly normal item recognition over a large number of tests. We directly compared her performance as measured using a visual paired comparison task (VPC) with her perf...

Summary: | In this study, we have examined visual recognition memory in a patient, YR, with discrete hippocampal damage who has shown normal or nearly normal item recognition over a large number of tests. We directly compared her performance as measured using a visual paired comparison task (VPC) with her performance on delayed matching to sample (DMS) tasks. We also investigated the effect of retention interval between familiarisation and test. YR shows good visual recognition with the DMS task up to 10
s after the familiarisation period, but only shows recognition with the VPC task for the shortest retention interval (0
s). Our results are consistent with the view that hippocampal damage disrupts recollection and recall, but not item familiarity memory. |
