Abstract

Objective: We investigated intentionally fabricated autobiographical memories in Alzheimer's Disease (AD).

Method: We invited AD patients and control participants to construct real events as well as fabricated events describing fictitious personal events that occurred in the past.

Results: Results demonstrated slower retrieval time for intentionally fabricated memories than for real ones in both AD patients and control participants. The analysis also showed similar vividness for intentionally fabricated memories and real ones in AD patients but lower vividness for intentionally fabricated memories than for real ones in control participants.

Conclusions: The slow retrieval time of intentionally fabricated memories may be attributed to the cognitive effort required to retrieve elements from autobiographical memory and edit them to construct a new memory. We suggest that the vividness of intentionally fabricated memories observed in AD may induce confusion with real memories. In addition to the experimental approach of our study, we offer a theoretical rationale for intentionally fabricated autobiographical memories by situating them in the wider context of different facets of false memories in AD (e.g. confabulations, source monitoring errors).

捏造的过去:阿尔茨海默氏症患者故意捏造的自传式记忆。

目的:探讨阿尔茨海默病(AD)患者故意编造的自传体记忆。方法:邀请AD患者和对照组参与者构建真实事件和虚构事件，虚构事件描述过去发生的个人事件。结果:结果表明，在阿尔茨海默病患者和对照组中，有意编造的记忆比真实记忆的恢复时间要慢。分析还显示，阿尔茨海默病患者有意编造的记忆与真实记忆的生动性相似，但对照组参与者有意编造的记忆的生动性低于真实记忆。结论:故意编造记忆的提取时间较慢可能是由于从自传体记忆中提取元素并编辑它们以构建新记忆需要认知努力。我们认为在AD中观察到的故意编造的记忆的生动性可能会导致与真实记忆的混淆。除了我们研究的实验方法外，我们还通过将故意编造的自传式记忆置于AD中错误记忆的不同方面的更广泛背景中(例如虚构，源监测错误)，为故意编造的自传式记忆提供了理论依据。

期刊介绍： Cognitive Neuropsychiatry (CNP) publishes high quality empirical and theoretical papers in the multi-disciplinary field of cognitive neuropsychiatry. Specifically the journal promotes the study of cognitive processes underlying psychological and behavioural abnormalities, including psychotic symptoms, with and without organic brain disease. Since 1996, CNP has published original papers, short reports, case studies and theoretical and empirical reviews in fields of clinical and cognitive neuropsychiatry, which have a bearing on the understanding of normal cognitive processes. Relevant research from cognitive neuroscience, cognitive neuropsychology and clinical populations will also be considered. There are no page charges and we are able to offer free color printing where color is necessary.
