Abstract
The purpose of this study was to examine the psychophysiological response to performance of making string figures with one's fingers. 8 healthy females were played two tasks, one was easy task and the other was difficult task, and repeated for five minutes. EEG, the mood scale for measuring psychological arousal level and hedonic tone, the self-assessment (skillfulness, concentration, enjoyment) about each performance. The data of EEG, the mood scale, self-assessment were compared in 2 tasks. The results were as follows. (1) In parietal area, beta activities in easy task were decreased in comparison with difficult task for three minutes of the latter half. (2) In the mood scale for measuring psychological arousal level and hedonic tone, "low arousal and pleasurable" score in a difficult task was decreased in comparison with easy task. (3) In self-assessment, "skillfulness" score in easy task was higher than difficult task, "concentration" score in difficult task was higher than easy task. These results suggested that the enjoyment of a string figure was difficulty and feeling of skillfulness by repetition, and concentration and EEG activity in difficult task of string figures were maintained.
