Episodic specific induction (ESI) is a manipulation shown to enhance episodic memory function. Episodic specificity induction involves thoroughly unpacking a recently encoded memory, with this enhanced retrieval-induced process helping to facilitate subsequent cognitions. In addition to ESI, emerging work suggests that acute exercise may also help to facilitate episodic memory function. The purpose of this study was to evaluate the potential individual and combined effects of acute exercise and ESI on subsequent episodic memory performance. : Participants ( = 120) were randomly assigned into one of four groups, (1) ESI and exercise (ESI + E), (2) ESI only (ESI), (3) exercise only (E), and (4) no ESI and no exercise (Control; C). The ESI protocol involved watching a short video and then recalling details about the setting, people, and actions in the video. The exercise protocol involved an acute bout (15 min) of treadmill exercise. After these tasks, episodic memory function was evaluated with an autobiographical interview assessment and a computerized episodic memory task involving what-where-when integration. We did not observe significant main effects for exercise or ESI on memory function but did observe some suggestive evidence of an interaction effect of these two parameters on episodic memory. That is, for the exercise group, memory performance was higher when combined with ESI as opposed to without ESI. Acute exercise and ESI may interact to influence episodic memory function.
情景特异性诱发（ESI）是一种被证明可以增强情景记忆功能的操作。情景特异性诱发涉及彻底分解最近编码的记忆，这种增强的检索诱发过程有助于促进随后的认知。除了 ESI，新兴的研究还表明，急性运动也可能有助于促进情景记忆功能。本研究的目的是评估急性运动和 ESI 对随后情景记忆表现的潜在个体和联合影响。参与者（n=120）被随机分配到以下四个组之一：（1）ESI 和运动（ESI+E）、（2）仅 ESI（ESI）、（3）仅运动（E）和（4）无 ESI 和无运动（对照；C）。ESI 方案涉及观看一段短视频，然后回忆视频中关于场景、人物和动作的细节。运动方案涉及急性跑步机运动（15 分钟）。在这些任务之后，通过自传式访谈评估和涉及何时何地整合的计算机化情景记忆任务评估情景记忆功能。我们没有观察到运动或 ESI 对记忆功能的显著主要影响，但确实观察到这两个参数对情景记忆的相互作用的一些提示性证据。也就是说，对于运动组，与没有 ESI 相比，与 ESI 结合时记忆表现更高。急性运动和 ESI 可能相互作用影响情景记忆功能。
