The purpose of the present research was to examine the influence of cognitive processes on discourse global coherence ability measured across different discourse tasks and collected from younger (n = 40; 20-39 years) and older (n = 40; 70-87 years) cognitively healthy adults. Study participants produced oral language samples in response to five commonly used discourse elicitation tasks and they were analyzed for maintenance of global coherence. Participants also completed memory and attention measures. Group differences on the global coherence scale were found for only one type of discourse-recounts. Across discourse elicitation tasks the lowest global coherence scores were found for recounts compared to the other discourse elicitation tasks. The influence of cognitive processes on maintenance of global coherence differed for the two age groups. For the younger group, there were no observed significant relationships. For the older group, cognitive measures were related to global coherence of stories and procedures.
本研究旨在考察认知过程对不同话语任务中整体连贯性能力的影响，这些任务的数据来自于认知健康的年轻组（n=40；20-39 岁）和年长组（n=40；70-87 岁）。研究参与者对五个常用的话语引出任务做出口头语言样本，并对其整体连贯性进行分析。参与者还完成了记忆和注意力测试。在整体连贯性量表上，只有一种类型的话语——记叙文，出现了组间差异。在不同的话语引出任务中，与其他话语引出任务相比，记叙文的整体连贯性得分最低。认知过程对两个年龄组整体连贯性的维持有不同的影响。对于年轻组，没有观察到显著的关系。对于年长组，认知测量与故事和程序的整体连贯性有关。
