项目摘要

The proposed project seeks to examine and understand individual differences underlying the occurrence of false memories, which is defined as remembering an event incorrectly or differently than how it originally occurred. The investigation of individual differences underlying both cognitive and neural variability in memory performance will be a critical factor in understanding the sources of false memories across the lifespan. By understanding the mechanisms that lead to these memory errors, we can better understand how to avoid these errors. The project will examine the benefits of a cognitive training strategy aimed at reducing false memories in older individuals. The research will use both behavioral and neuroimaging (fMRI) methods to understand the basis of false memories. Neuroimaging analyses will include univariate, functional connectivity, and multivariate analyses to uncover the neural mechanism underlying both true and false memories. This will expand understanding of factors that contribute to false memories across the lifespan. The research will train undergraduate and graduate students on cognitive neuroscience of memory and cognitive aging and will educate the public about memory and cognitive processes that change with age. Memory research typically aims to identify how memories are represented in the brain. Aging research typically aims to identify sources of age-related deficits in memory. The current proposal combines these goals to reveal the cognitive and neural processes underlying a significant source of error in cognitive aging, that of false memories. The long-term goal is to identify domain-general and domain-specific sources of variance associated with false memories across the lifespan and identify effective, evidence-based strategies for reducing memory errors. This project aims to identify the cognitive and neural markers of such variance as well as individual differences factors that contribute to false memories. The research will also examine the effects of cognitive training in older adults to successfully reduce the incidence of false memories. To do so, the work will utilize behavioral methods examining individual differences in false memories in older adults, as well as advanced neuroimaging methods to investigate how neural information is processed, and represented, throughout the brain. By understanding both common and unique influences associated with the susceptibility to false memories across difference sources, the project can identify strategies for effectively reducing false memories, thereby ameliorating age-related memory decline.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该项目旨在研究和理解错误记忆发生背后的个体差异,错误记忆被定义为错误地记住一件事或与最初发生的情况不同。对记忆表现中认知和神经变异的个体差异的研究将是理解一生中错误记忆来源的关键因素。通过了解导致这些内存错误的机制,我们可以更好地了解如何避免这些错误。该项目将检验旨在减少老年人错误记忆的认知训练策略的好处。这项研究将使用行为和神经成像(fMRI)方法来了解错误记忆的基础。神经成像分析将包括单变量、功能连接和多变量分析,以揭示真实和错误记忆背后的神经机制。这将扩大对一生中导致错误记忆的因素的理解。这项研究将对本科生和研究生进行记忆认知神经科学和认知衰老方面的培训,并将教育公众关于记忆和认知过程随年龄变化的知识。记忆研究通常旨在确定记忆在大脑中的表现方式。衰老研究通常旨在确定与年龄相关的记忆缺陷的来源。目前的研究将这些目标结合起来,以揭示认知老化中错误的一个重要来源——错误记忆——背后的认知和神经过程。长期目标是确定在整个生命周期中与错误记忆相关的一般领域和特定领域的差异来源,并确定有效的、基于证据的减少记忆错误的策略。本项目旨在识别这种差异的认知和神经标记,以及导致错误记忆的个体差异因素。这项研究还将检验认知训练对老年人的影响,以成功地减少错误记忆的发生率。为了做到这一点,这项工作将利用行为方法来检查老年人错误记忆的个体差异,以及先进的神经成像方法来研究神经信息是如何在整个大脑中被处理和表征的。通过了解与不同来源的错误记忆易感性相关的共同和独特影响,该项目可以确定有效减少错误记忆的策略,从而改善与年龄相关的记忆衰退。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
