摘要

大脑处理短间隔时间,但也允许人们将自己投射到过去和未来(即精神时间旅行[MTT])。β振荡指数秒-长间隔计时(即,更高的β功率与更长的持续时间有关)。在这里,我们使用顶叶经颅交流电刺激(tACS)来研究MTT是否也受到顶叶β振荡的支持,并测试MTT与短间隔之间的联系。30名成年人在接受β和α tACS刺激的同时进行了一项新的MTT任务。β tACS在过去的MTT中对应于时间低估,但在未来的MTT中不对应。此外,在过去投射MTT条件下,高估秒间隔的参与者也高估了时间距离,并表现出更强的β - tACS效应。这些数据为时间感知提供了一个独特的窗口,显示了β振荡如何可能是短时间间隔和MTT的共同机制。

The Role of Beta Oscillations in Mental Time Travel.

The brain processes short-interval timing but also allows people to project themselves into the past and the future (i.e., mental time travel [MTT]). Beta oscillations index seconds-long-interval timing (i.e., higher beta power is associated with longer durations). Here, we used parietal transcranial alternating current stimulation (tACS) to investigate whether MTT is also supported by parietal beta oscillations and to test the link between MTT and short intervals. Thirty adults performed a novel MTT task while receiving beta and alpha tACS, in addition to no stimulation. Beta tACS corresponded to a temporal underestimation in past but not in future MTT. Furthermore, participants who overestimated seconds-long intervals also overestimated temporal distances in the past-projection MTT condition and showed a stronger effect of beta tACS. These data provide a unique window into temporal perception, showing how beta oscillations may be a common mechanism for short intervals and MTT.

期刊介绍: Psychological Science, the flagship journal of The Association for Psychological Science (previously the American Psychological Society), is a leading publication in the field with a citation ranking/impact factor among the top ten worldwide. It publishes authoritative articles covering various domains of psychological science, including brain and behavior, clinical science, cognition, learning and memory, social psychology, and developmental psychology. In addition to full-length articles, the journal features summaries of new research developments and discussions on psychological issues in government and public affairs. "Psychological Science" is published twelve times annually.
