Abstract：
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.
摘要：
年轻人认为世界的移动速度比成年人慢，这是一个熟悉的现象。然而，这仍然是一个悬而未决的问题，为什么会这样。利用事件分割理论，使用人工神经网络方法进行脑电图（EEG）波束形成和非线性因果关系估计，我们研究了青少年和成人参与者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成有意义的单元时，青少年将传入信息划分为比成年人更少的封装片段或持续时间更长的片段。重要的是,在特定的神经振荡谱中，内侧额叶和下层感知区域之间以及枕部-颞部区域之间的定向交流解释了组间的行为差异。总的来说,这项研究表明，大脑区域之间定向通信的不同组织和大脑区域之间信息的低效传输是理解为什么年轻人认为世界移动缓慢的关键。
