Priming and cued recall in elderly, alcohol intoxicated and sleep deprived subjects: a case of functionally similar memory deficits.
Young, old, alcohol intoxicated, and sleep deprived subjects studied weakly and strongly related word pairs, and were tested in lexical decision priming and cued recall. Results showed memory deficits for old, alcohol intoxicated, and sleep deprived subjects in cued recall of weakly related pairs. In contrast, there were no differences between these three groups and a control group of young subjects in cued recall of strongly related pairs, and there were no differences between groups in priming. This pattern of results is interpreted to support (a) a hypothesis of functional similarities between the memory deficits associated with adult ageing, alcohol intoxication, and sleep deprivation; (b) the notion that memory deficits in these subjects are more likely to occur in tasks which require effortful rather than automatic processes; and (c) the view that the memory deficits observed are due to inefficiencies at both encoding and retrieval.
