    Abstract:
    This study examines the effects of contextual cueing on the remote memory of alcoholic Korsakoff patients and normal subjects. Naming of personalities who became famous in each of the five decades beginning 1935 was tested under two conditions: "no-context", in which minimal extraneous cues to identification were provided, and "context", where clear extraneous cues were available. Normal subjects performed better than Korsakoff patients, showed no evidence of a temporal gradient, and exhibited a contextual cueing advantage across all decades. In contrast, Korsakoff patients demonstrated a marked temporal gradient, and the contextual cueing advantage declined systematically as more recent decades were sampled. Further analyses demonstrated that the differential pattern of deficits shown by Korsakoffs and controls was not attributable to absolute differences in performance level. Theoretical implications of these data for explanations of Korsakoff retrograde amnesia are discussed.
