要約(日本語): Alpha-band oscillations (8?13 Hz) are the dominant waves in the human brain, and are enhanced during internal tasks such as mental arithmetic task. Although it plays an active role in information processing, it remains questionable whether oscillations from external stimuli have the same effect. Therefore, we explore whether the entrained oscillations generated by background flicker affect people’s arithmetic performance and information processing in short-term working memory. In the experiment, subjects are supposed to remember “odd” or “even” cue at the beginning of each trial. After watching the flicker for 4 seconds at 7.5Hz, 10.5Hz, 16.5Hz or 0Hz (no flicker), they need to do simple calculation to determine if the result is odd or even. Current results indicate that the reaction time of the experimental group is faster than that of the control group. Correlation has been shown between subjects’ EEG level and the reaction time. Entrained oscillations may help people become more sensitive and cognitive.
