Episodic future thinking (EFT) has been linked with our ability to remember past events. However, its specific neurocognitive subprocesses have remained elusive. In Experiment 1, a study of healthy older adults was conducted to investigate the candidate subprocesses of EFT. Participants completed a standard EFT cue word task, two memory measures (Verbal Paired Associates I, Source Memory), and two measures of executive function (Trail Making Test, Tower Test). In Experiment 2, healthy young adults also completed an EFT task and neuropsychological measures. The link between neurocognitive measures and five characteristics of EFT was investigated. Specifically, it was found that Source Memory and Trail Making Test performance predicted the episodic specificity of future events in older but not younger adults. Replicating previous findings, older adults produced future events with greater semantic but fewer episodic details than did young adults. These results extend the data and emphasize the importance of the multiple subprocesses underlying EFT.
情景式未来思维(EFT)与我们记忆过去事件的能力有关。然而,其具体的神经认知子过程仍不明确。在实验1中,对健康的老年人进行了一项研究,以调查EFT的候选子过程。参与者完成了一项标准的EFT提示词任务、两项记忆测量(言语配对联想I、来源记忆)以及两项执行功能测量(连线测验、塔测验)。在实验2中,健康的年轻人也完成了一项EFT任务和神经心理学测量。研究了神经认知测量与EFT的五个特征之间的联系。具体而言,发现来源记忆和连线测验的表现预测了老年人而非年轻人未来事件的情景特异性。重复之前的研究结果,与年轻人相比,老年人产生的未来事件具有更多的语义细节但情景细节更少。这些结果扩展了数据,并强调了EFT背后多个子过程的重要性。
