As expected, the ratings on the subjective evaluation items representing the flow state were the highest in the Flow condition. Furthermore, the correlations between subjective flow items and EEG activity were examined. Post-trial self-report of the flow state and EEG during task execution were measured and compared among three conditions (Boredom, Flow, and Overload) that had different levels of task difficulty. A total of 16 participants (10 males, 6 females) participated in the experiment that employed a mental arithmetic task developed in a previous study. The present study utilized an electroencephalogram (EEG) during an experimentally evoked flow state and examined the possibility of objective measurement of immediate flow. To verify the positive effects of flow and develop a method to utilize it, the establishment of a reliable measurement of the flow state is essential. 2Research Center for Kansei Value Creation, Kwansei Gakuin University, Sanda, Japanįlow experience is a subjective state experienced during holistic involvement in a certain activity, which has been reported to function as a factor promoting motivation, skill development, and better performance in the activity.1School of Science and Technology, Kwansei Gakuin University, Sanda, Japan.
