One group of normal elderly adults and two groups of cognitively impaired elderly adults were compared on an implicit and an explicit memory task. Degree of impairment affected explicit memory; the mildly and moderately impaired elderly adults demonstrated significantly reduced recognition performance. Degree of impairment also affected implicit memory priming performance, particularly for low frequency items, as measured by a word completion task. Explicit memory performance declined for both cognitively impaired groups, but implicit memory performance was sensitive to the degree or severity of impairment, causing a decline in performance only in the moderately impaired group.
对一组正常老年人和两组认知受损老年人进行了一项内隐记忆任务和一项外显记忆任务的比较。损伤程度影响外显记忆；轻度和中度受损的老年人表现出显著降低的识别能力。损伤程度也影响内隐记忆启动表现，特别是对于低频项目，通过单词完成任务进行测量。两个认知受损组的外显记忆表现均下降，但内隐记忆表现对外伤程度或严重程度敏感，仅在中度受损组中导致表现下降。
