Performance of alcoholic and brain-damaged subjects on the Luria Memory Words test.
Verbal memory was evaluated in groups of 36 community controls, 50 pseudoneurological controls, 50 alcoholics, and 50 brain-damaged patients. All participants were men between the ages of 22-61. Groups did not differ in age or educational levels (F < 1). Groups were compared on their performance on the Luria Memory Words Test. Dependent variables included the number of correct words over learning trials, the trial of best performance, and the number of words recalled at three delayed trials (2, 8, and 30 min after learning). Brain-damaged subjects were inferior to community controls on all measures. Pseudoneurological controls were inferior to community controls on delayed recall, but were equivalent on measures of learning. Alcoholics were inferior to controls on measures of learning but did not differ on measures of recall. Implications regarding the underlying deficit in alcoholics' verbal memory, the use and interpretation of the Luria Memory Words test, and the use of pseudoneurological patients as controls are discussed.
