Abstract
-
Five nonverbal recognition memory tasks, using faces (meaningful) and computer-generated random shapes (nonmeaningful), were presented to alcoholic Korsakoff patients and normal controls. The results show that when target and distractor items came from different categories, normals showed facilitation in performance while Korsakoffs exhibited increasing disruption in performance over three recognition probes. On tasks utilizing "mixed" stimuli as targets and distractors, Korsakoff performance, although poor, was above chance and resembled normal patterns. This held true for both meaningful and nonmeaningful material. The theory that the activation of a pre-existing network of specific memory representations is sufficient to explain Korsakoff recognition memory is discussed and an alternative "competitive priming" hypothesis is proposed.
