老年女性（平均 69 岁）和年轻女性（平均 23 岁）接受了 100 次韦克斯勒成人智力量表 (WAIS) 的数字符号替换子测试，并进行了修改，以便在 5 个训练日中每天的数字符号键有所不同。年长女性在培训期间和培训期间都取得了显着进步，但年轻女性也取得了同样大的进步，因此年龄差异并未因培训而缩小。经过练习，老年女性在标准 WAIS 子测试中的分数相对于年轻人的标准从第 25 个百分位数提高到第 90 个百分位数，并且这些分数在 10 天后的后续测试中保持不变。尽管练习效果转移到与训练键不同的数字符号键，但改进并没有推广到 WAIS 数字跨度性能或包含训练任务某些元素的匹配任务。
Older women (mean = 69 yr) and younger women (mean = 23 yr) received 100 administrations of the digit symbol substitution subtest of the Wechsler Adult Intelligence Scale (WAIS), modified so that the digit-symbol keys differed on each of the 5 training days. The older women improved substantially both within and between training sessions but equally large gains were made by the younger women so that age differences were not reduced by training. As a consequence of practice, scores of the older women on the standard WAIS subtest increased from the 25th to the 90th percentile relative to norms for young adults and these scores were maintained during a follow-up test 10 days later. Although practice effects transferred to digit-symbol keys different from the training keys, improvements did not generalize to WAIS digit span performance or to a matching task containing some of the elements of the training task.
