Imagination as a source of false memories in younger and older adults: cognitive and brain mechanisms.

本博士论文的研究旨在调查虚假记忆形成和恢复的认知和大脑机制，以及这些机制在年轻人和老年人中的差异。人们一致发现，随着年龄的增长，情景记忆表现会恶化，这与记忆相关的大脑活动的变化有关（例如Friedman，Nessler &约翰逊，2007; Rugg，弗莱彻，Frith，Frackowiak，Dolan，1997; Naveh-Benjamin，Brev & Levy，2007）。然而，关于年龄相关的认知变化如何影响错误记忆的形成，以及错误记忆如何影响对实际发生事件的记忆的证据较少。本文提出的研究旨在解决这些问题。脑电图（EEG）和行为的方法将被用来调查的机制，通过这些机制，真实事件的反事实版本被想象，并随后错误地回忆为真实的。

The research in this PhDaims to investigate the cognitive and brain mechanisms underlying the formation and retrieval of false memories, and how these differ across younger and older adults. It is consistently found that episodic memory performance deteriorates as we age, which is associated with changes in memory-related brain activity (e.g. Friedman, Nessler & Johnson, 2007; Rugg, Fletcher, Frith, Frackowiak, Dolan, 1997; Naveh-Benjamin, Brev & Levy, 2007). However, there is less evidence on how age-related cognitive changes influence the formation of false memories, and how false memories affect memories of events that actually happened. The research proposed here aims to address these issues. Electroencephalography (EEG) and behavioural methods will be used to investigate the mechanisms by which counterfactual versions of true events are imagined and subsequently falsely recalled as real.
