ABSTRACT This study investigates coherence of discourse in the production of autobiographical narratives by individuals with aMCI. Autobiographical interviews were analyzed to determine whether reduced episodic recall was related to deficits in discourse coherence. A coherence rating scale was used to evaluate relatedness of the autobiographical details produced by participants to the topic of discourse. Interviews were transcribed, segmented into details, and divided into sets of episodic, semantic, or supplementary information, which were subsequently analysed with the coherence rating scale. We predicted that the known episodic deficits observed in aMCI could also affect the retrieval of coherent episodic information. The results revealed deficits in coherence could be found in both episodic and semantic information in the aMCI group. These results suggest that the cognitive deficits experienced by individuals with aMCI may go beyond their known difficulty in recalling episodic details, as they also affect the controlled retrieval of both episodic and semantic information.

情景记忆衰退与话语连贯性缺陷有关

摘要 本研究调查了 aMCI 患者在制作自传式叙事时话语的连贯性。分析自传式访谈以确定减少的情景回忆是否与话语连贯性缺陷有关。连贯性评分量表用于评估参与者产生的自传细节与话语主题的相关性。访谈被转录，细分为细节，并分为情节、语义或补充信息集，随后用连贯性评分量表进行分析。我们预测在 aMCI 中观察到的已知情节缺陷也可能影响连贯情节信息的检索。结果显示，在 aMCI 组的情节和语义信息中都可以发现连贯性缺陷。
