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.
年轻、年老、酒精中毒和睡眠不足的受试者学习了弱相关和强相关的词对,并接受了词汇判断启动和线索回忆测试。结果显示,年老、酒精中毒和睡眠不足的受试者在弱相关词对的线索回忆中存在记忆缺陷。相比之下,在强相关词对的线索回忆中,这三组与年轻受试者对照组之间没有差异,在启动方面各小组之间也没有差异。这种结果模式被解释为支持:(a)与成年衰老、酒精中毒和睡眠不足相关的记忆缺陷之间存在功能相似性的假设;(b)这些受试者的记忆缺陷更可能出现在需要费力而非自动过程的任务中的观点;以及(c)观察到的记忆缺陷是由于编码和检索效率低下的观点。
