标准化样本从WMS-III（N = 1250），年龄从16岁到89岁不等，被用来确定是否编码，检索，或存储的语言和空间信息是最受影响的正常老化。对逻辑记忆和视觉再现的即时和延迟回忆和再认进行了检查。即时言语和空间回忆显着恶化随着年龄的增长，和年龄相关的延迟回忆和识别的恶化在很大程度上解释了较差的即时记忆。这些发现与延迟后保留百分比的较小老化效应相一致，表明老化效应是由于编码的恶化而不是检索或存储新信息。虽然视觉再现随着年龄的增长比逻辑记忆更快地恶化，但作为年龄函数的性能递减模式在两个测试中是相当的。第五个十年首次出现业绩下降，随后逐渐恶化，直到第八个十年再次出现急剧下降。这些结果表明，更依赖于额叶的功能比更依赖于颞叶的功能更容易受到衰老的影响。
The standardization sample from the WMS-III (N = 1250), which varied in age from 16 to 89, was used to determine whether encoding, retrieval, or storage of verbal and spatial information was most affected by normal aging. Immediate and delayed recall and recognition of Logical Memory and Visual Reproduction were examined. Immediate verbal and spatial recall significantly deteriorated with increasing age, and the age-associated deterioration in delayed recall and recognition was largely explained by poorer immediate memory. These findings, in concert with the smaller aging effects for percent retention after a delay, suggest that the aging effect is due to deterioration in encoding more than retrieval or storage of new information. While Visual Reproduction deteriorated more rapidly with age than Logical Memory, the pattern of performance decrements as a function of age were comparable across both tests. Decreases in performance were first seen in the fifth decade with gradual deterioration until the eighth decade when there was another precipitous drop. These results suggest that functions that are more dependent on the frontal lobes are more vulnerable to aging than those that are more dependent on the temporal lobes.
