对80名年轻人和80名老年人的113个刺激词的单词联想进行了比较。聚合反应的比例随刺激词的语法类别和受试者的词汇水平而变化，但不随年龄而变化。同样比例的年轻人和老年人给出了最常见的回答。尽管老年人有更多的独特反应，但这似乎反映了词汇水平的年龄差异，因为词汇而不是年龄是一个很好的预测因子。受试者内部的变异性在不同年龄之间也是相似的，因为在重新测试中，年轻人和老年人给出的反应与原始测试中的相同比例相同。这两个年龄段的人在重测中更有可能重复常见的回答。这一点，加上对反应延迟的分析，表明不同年龄段的人都在同等程度上使用战略流程。结果表明，成年人的语义结构和语义编码与言语能力有关，而与年龄无关。
Word associations of 80 young and 80 older adults were compared for 113 stimulus words. The proportion of paradigmatic responses varied with the grammatical class of the stimulus word and with the vocabulary level of the subject, but not with age. The same proportion of young and older adults gave the most common responses. Although older adults had a greater number of unique responses, this seems to reflect age differences in vocabulary level, as vocabulary but not age was a good predictor. Within-subject variability was also comparable across age, as on a retest young and older adults gave the same proportion of responses that were identical to those on the original test. Both age groups were more likely to repeat common than uncommon responses on the retest. This, together with analyses of response latency, suggests equivalent use of strategic processes across age. The results indicate that semantic structure and semantic encoding in adults are related to verbal ability, but not to age.
