The premature aging hypothesis: old before its time?
This study tested the hypothesis that alcoholism results in premature aging of memory functioning. It was proposed that support for the premature aging hypothesis must come from qualitative as well as quantitative similarities between younger alcoholics and older controls. The California Verbal Learning Test (CVLT) was administered to young and old alcoholics and to young and old controls. The CVLT provides measures of recall, recognition, learning strategies, and error types. Alcoholism and aging produced similar levels of immediate and delayed free recall. However, poor recognition memory and more frequent intrusion and false positive errors were associated with alcoholism but not with aging. Qualitative differences in error types between alcoholism and aging were also found. Results indicated that alcoholism and aging produce independent verbal learning decrements.
