Abstract
Flow 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. 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. The present study utilized an electroencephalogram (EEG) during an experimentally evoked flow state and examined the possibility of objective measurement of immediate flow. A total of 16 participants (10 males, 6 females) participated in the experiment that employed a mental arithmetic task developed in a previous study. 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. Furthermore, the correlations between subjective flow items and EEG activity were examined. As expected, the ratings on the subjective evaluation items representing the flow state were the highest in the Flow condition. Regarding the EEG data, theta activities in the frontal areas were higher in the Flow and the Overload conditions than in the Boredom condition, and alpha activity in the frontal areas and the right central area gradually increased depending on the task difficulty. These EEG activities correlated with self-reported flow experience, especially items related to the concentration on the task and task difficulty. From the results, the flow state was characterized by increased theta activities in the frontal areas and moderate alpha activities in the frontal and central areas. The former may be related to a high level of cognitive control and immersion in task, and the latter suggests that the load on the working memory was not excessive. The findings of this study suggest the possibility of distinguishing the flow state from other states using multiple EEG activities and indicate the need for other physiological indicators corresponding to the other aspects of flow experience.
Highlights
In any task, for better performance, performing at one’s full potential in individual situations and obtaining the required skills in advance are important
The performance of mental arithmetic task was assessed in terms of the percentage of correct answers
Items 1, 3, and 6 that were used to calculate a composite variable as the representatives of flow in the previous research were included in the factor of balance between challenge and skill; this confirmed the agreement between this study and the previous one regarding the measurement of subjective states
Summary
For better performance, performing at one’s full potential in individual situations and obtaining the required skills in advance are important. The development of an individual’s ability through training or performance, specific to each activity, enables better performance. An optimal psychological state that contributes to these goals can be a common promotional factor across various types of activity. The most promising optimal psychological state is the flow experience proposed by Csikszentmihalyi (2000). According to Csikszentmihalyi (2000), who originally proposed this concept, flow is the “holistic sensation that people feel when they act with total involvement.”.
