Research Abstract

To understand the neural basis of mental concentration, we developed a behavior paradigm, and measured EEG during meditation, one type of flow state. We employed a feature search task, known to have relatively small variability in task difficulty across trials, and found that time series of reaction time data contains significant long-range temporal correlation. EEG data during meditation showed that instead of increasing long-range temporal correlation, temporal fluctuation of the correlation is reduced compared with the rest period, suggesting that meditation makes our internal state more stable.
