摘要：SummaryWe encounter the world as a continuous flow and effortlessly segment sequences of events into episodes. This process of event segmentation engages working memory (WM) for tracking the flow of events and impacts subsequent memory accuracy. WM is limited in how much information (i.e., WM capacity) and for how long the information is retained (i.e., forgetting rate). In this study, across multiple tasks, we estimated participants’ WM capacity and forgetting rate in a dynamic context and evaluated their relationship to event segmentation. A U-shaped relationship across tasks shows that individuals who segmented the movie more finely or coarsely than the average have a faster WM forgetting rate. A separate task assessing long-term memory retrieval revealed that the coarse-segmenters have better recognition of temporal order of events compared to the fine-segmenters. These findings show that event segmentation employs dissociable memory strategies and correlates with how long information is retained in WMGraphical abstractDisplay OmittedHighlights•The event segmentation grain is variable across individuals•The event segmentation grain has a U-shaped relationship with the WM forgetting rate•The temporal order memory accuracy decreases with the increasing event segmentation•The number of recalled events increases with the increasing event segmentationBehavioral neuroscience; cognitive neuroscience; Neuroscience
