记忆功能的临床检查通常包括执行简单的自由回忆任务，比如几分钟后回忆几个单词。然而，人们对这些程序的规范参数或心理测量特性知之甚少，而且很少将这些技术与更全面、标准化的记忆指标进行比较。为了解决这些问题，对一大群精心挑选的50岁以上的健康受试者进行了两个三个单词的回忆任务。采用Mini-Mental State Examination （MMSE）作为整体认知状态的指标，采用California Verbal Learning Test （CVLT）排除记忆能力异常的被试。在两个三词回忆任务和CVLT结果之间发现了显著但适度的关系。在三个单词的回忆中发现了很大的可变性，正常受试者中有很大一部分回忆不起一个单词或一个单词。结果表明，在将简单的回忆表现解释为记忆指标时要谨慎，因为在健康（尤其是老年人）的个体中，结果也存在很大的可变性。
Clinical examination of memory functions often includes the administration of simple free recall tasks, such as the recall of several words following a few minutes. Little is known, however, about the normative parameters or psychometric properties of such procedures, and such techniques have rarely been compared with more comprehensive, well-standardized memory indices. To address these issues, two three-word recall tasks were administered to a large group of carefully selected healthy subjects over the age of 50 years. The Mini-Mental State Examination (MMSE) was obtained as an index of global cognitive status, and the California Verbal Learning Test (CVLT) was used to exclude subjects with abnormal memory abilities. Significant but modest relationships were found between two three-word recall tasks and CVLT results. Substantial variability was seen on three-word recall, with a significant proportion of normal subjects recalling zero or one word, Results suggest using caution in interpreting simple recall performance as an index of memory, as great variability in results is seen among healthy (particularly older) individuals.
