年轻人和老年人提供了语言样本，以回答问题，而步行，手指轻敲，忽略语音或噪音。语言样本在3个方面进行评分：流利性，复杂性和内容。工作记忆限制影响老年人言语产生的假设通过比较基线样本与参与者执行并行任务时产生的样本进行了测试。有基线差异：老年人的语言比年轻人的语言不流利，也不复杂。与老年人相比，年轻人采取了不同的策略来应对双重任务的要求：他们减少了句子长度和语法复杂性。相比之下，老年人在双重任务条件下转向降低语速。
Young and older adults provided language samples in response to questions while walking, finger tapping, and ignoring speech or noise. The language samples were scored on 3 dimensions: fluency, complexity, and content. The hypothesis that working memory limitations affect speech production by older adults was tested by comparing baseline samples with those produced while the participants were performing the concurrent tasks. There were baseline differences: Older adults' speech was less fluent and less complex than young adults' speech. Young adults adopted a different strategy in response to the dual-task demands than older adults: They reduced sentence length and grammatical complexity. In contrast, older adults shifted to a reduced speech rate in the dual-task conditions.
