Description

In this paper, by measuring EEG during the Kraepelin test, it was clarified that the optimal rhythm which maximized the number of answers was found to be 1.2-times, when the rhythm answering without rhythm was set at 1.0-times. It was clarified that when the optimum rhythm was listened to, the ratio of power spectrum for relaxation/concentration was higher, the standard deviation of that ratio was smaller, and the activation of the left and right brains was not unbalanced. The power spectrum of the EEG while listening to the rhythm and answering the Kraepelin test was estimated from the EEG when answering without rhythm, and the error was less than 10%.
