We experience the world in terms of both (continuous) time and (discrete) events, but time seems especially primitive-since we cannot perceive events without an underlying temporal medium. It is all the more intriguing, then, to discover that event segmentation can itself influence how we perceive the passage of time. We demonstrated this using a novel "rhythmic reproduction" task, in which people listened to irregular sequences of musical tones, and then immediately reproduced those rhythmic patterns from memory. Each sequence contained a single salient (and entirely task-irrelevant) perceptual event boundary, but the temporal placement of that boundary varied across multiple trials in which people reproduced the same underlying rhythmic pattern. Reproductions were systematically influenced by event boundaries in two complementary ways: tones immediately following event boundaries were delayed (being effectively played "too late" in the reproductions), while tones immediately preceding event boundaries were sped up (being effectively played "too early"). This demonstrates how event segmentation influences time perception in subtle and nonuniform ways that go beyond global temporal distortions-with dilation across events, but contraction within events. Events structure temporal experience, facilitating a give-and-take between the subjective expansion and contraction of time. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
