三个单词的回忆任务被广泛用作言语记忆功能的简单测量，尽管测试说明和程序的不同使对表现的解释变得复杂。本研究的目的是考察52-75岁(男性=70岁)和76-92岁(男性=82岁)健康受试者的3个单词回忆成绩，并与阿尔茨海默病(AD)患者进行比较。在短暂的延迟后，年轻老年组的受试者记住的单词显著多于老年受试者(M=2.8和2.3)。然而，大多数对照被试在延迟回忆后回忆起2到3个单词，50-75岁组中只有3%的人在延迟回忆时回忆起0或I词，76岁以上组中只有17%的人回忆起延迟回忆。这与87%的AD患者回忆0或i单词的比例形成了鲜明对比。尽管3个单词的回忆成绩随着年龄的增长而下降，但在大多数正常年龄的情况下，可以预期良好的回忆(2到3个单词)。
Three-word recall tasks are widely used as brief measures of verbal memory function, although interpretation of performance is complicated by variations in test instructions and procedures. The purpose of this study was to examine 3-word recall performance in samples of healthy subjects aged 52-75 (M age = 70) and age 76-92 (M age = 82) compared to patients with Alzheimer's Disease (AD) when explicit prompts to remember the words were given. Those in the younger aging group remembered significantly more words than those in the older sample after a brief delay (M = 2.8 and 2.3, respectively). However, the majority of control subjects recalled 2 or 3 words after the delay, with only 3% of the 50-75 year old group and 17% of the 76+ year old group recalling 0 or I word on delayed recall. This is in stark contrast to the 87% of individuals with AD who recalled 0 or I word. Even though 3-word recall performance decreases with age, good recall (2 or 3 words) can be expected in most cases of normal aging.
