We recently reported that older adults generate fewer episodic details than younger adults when remembering past events and when simulating future events. We suggested that the simulation findings reveal an age deficit in recombining episodic details into novel events, but they could also result from older adults "recasting" entire past events as future events. In this study, we used an experimental recombination paradigm to prevent recasting while imagining and to compare imagining the future with imagining the past. Older adults generated fewer episodic details for imagined and recalled events than younger adults, thereby extending the age-related simulation deficit to conditions of recombination.
我们最近报告称,老年人在回忆过去事件和模拟未来事件时,产生的情节细节比年轻人少。我们认为,模拟结果揭示了老年人在将情节细节重新组合成新事件方面存在年龄缺陷,但也可能是因为老年人将整个过去事件“重铸”为未来事件。在这项研究中,我们使用了一种实验性的重组范式来防止重铸,同时想象过去和未来,并比较想象未来和回忆过去。与年轻人相比,老年人对想象和回忆的事件产生的情节细节较少,从而将与年龄相关的模拟缺陷扩展到重组条件下。
