The purpose of this study was to clarify the relationship between cognitive skill and concentration, based on brain waves measured before and after eSports activity. Participants were twenty male collegiate students belonging to an eSports club (Mean Age ± 21.40, SD = 1.65). At first, participants were put on a simple electroencephalograph (EEG) and their psychological state at rest was measured for 2 minutes. After that, Stroop Color Word Test (SCWT) was conducted to measure their cognitive skill (execution function) before the eSports activity. In addition, after the eSports activity, SCWT was conducted again. In this study, the HAKARO series Stroop test (Digital Standard Co., Ltd.) was used to measure cognitive skill (execution function). To examine the degree of concentration during eSports activity, this study adopted a simple band-type EEG that only measures the Fp1 point as defined by the international 10-20 systems. In addition, for analyzing concentration, Sports KANSEI, which is a software for estimating the degree of concentration from the combination of raw EEG data, was used. As a result, this study indicated that cognitive skill (executive function) might be improved before and after eSports activity, and concentration might appear during eSports play. However, research on eSports is still in its accumulation stage in Japan, so further investigation might be necessary.
