中年和老年健康受试者进行了非正式的采访，他们的话语生产进行了分析，以测试与年龄相关的变化，在特定的语言，微观语言，并在更高层次的组织，宏观语言能力。在微观语言学指标上，包括句法复杂性、句法和词汇产生错误，没有发现显著的年龄差异，在词汇衔接关系的使用上，如回指，也没有发现年龄差异。然而，年龄较大的科目，获得显着较低的评级的宏观语言措施的全球主题连贯性。老年受试者未能保持连贯的参考一般话题的话语，虽然他们保持连贯的意义之间的关系连续的话语。这些结果是最兼容的观点，即年龄相关的性能下降的语言任务主要反映了宏语言能力的变化，需要整合的语言和非语言的认知过程，而不是在语言特定的认知过程的变化。
Middle-aged and elderly healthy subjects were interviewed informally, and their discourse productions were analyzed to test for age-related changes in language-specific, microlinguistic, and in higher order organizational, macrolinguistic abilities. No significant age differences were found on microlinguistic measures, including syntactic complexity and syntactic and lexical production errors, and there were also no age differences in the use of lexical cohesive ties, such as anaphora. Older subjects, however, obtained significantly lower ratings on a macrolinguistic measure of global thematic coherence. Elderly subjects failed to maintain coherent reference to the general topic of discourse, although they preserved coherent meaning relationships between contiguous utterances. These results are most compatible with the view that age-related performance declines on language tasks primarily reflect changes in macrolinguistic abilities that require integration of linguistic and nonlinguistic cognitive processes, rather than changes in language-specific cognitive processes.
