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.

这项研究调查了aMCI个人在自传体叙事产生中话语的连贯性。通过分析自传式访谈来确定情景回忆的减少是否与语篇连贯性的缺陷有关。一致性评定量表用于评估参与者所产生的自传体细节与话语主题的相关性。访谈被转录，细分为细节，并分成一些情节，语义或补充信息集，随后用一致性评级量表对其进行分析。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。结果表明，在aMCI组的情节和语义信息中都可能发现连贯性不足。
