Investigated whether alcoholic Korsakoff patients are impaired in categorizing neutral and emotional stimuli according to their valence and whether memory performance for this material is reduced. In a group of 25 Korsakoff patients (mean age 55.8 years) and 22 healthy control group participants (mean age 53.45 years), 2 experimental tasks (one containing emotional and neutral pictures and the other containing words) were administered. Results showed that patients had difficulties in affective judgments due to problems in classifying neutral stimuli. Memory for emotional and neutral material was impaired to a similar degree. Thus, the facilitating effect of emotional valence on memory performance is absent in Korsakoff patients.
