That younger individuals perceive the world as moving slower than adults is a familiar phenomenon. Yet, it remains an open question why that is. Using event segmentation theory, electroencephalogram (EEG) beamforming and nonlinear causal relationship estimation using artificial neural network methods, we studied neural activity while adolescent and adult participants segmented a movie. We show when participants were instructed to segment a movie into meaningful units, adolescents partitioned incoming information into fewer encapsulated segments or episodes of longer duration than adults. Importantly, directed communication between medial frontal and lower-level perceptual areas and between occipito-temporal regions in specific neural oscillation spectrums explained behavioral differences between groups. Overall, the study reveals that a different organization of directed communication between brain regions and inefficient transmission of information between brain regions are key to understand why younger people perceive the world as moving slow.
年轻人感知世界的速度比成年人慢，这是一种常见的现象。然而，为什么会这样仍然是一个悬而未决的问题。我们使用事件分割理论、脑电图 (EEG) 波束形成以及使用人工神经网络方法的非线性因果关系估计，研究了青少年和成年参与者在分割电影时的神经活动。我们展示了当参与者被指示将电影分割成有意义的单元时，青少年将传入信息分割成比成年人更少的封装片段或更长持续时间的片段。重要的是，中额前区和较低水平感知区之间以及特定神经振荡谱中的枕颞区之间的定向通信解释了组间的行为差异。总的来说，该研究表明，大脑区域之间定向通信的不同组织以及大脑区域之间信息传输的低效是理解为什么年轻人感觉世界移动缓慢的关键。
