| Research Abstract |
English rhythm instruction materials(RIM) encourage you to learn English rhythm. But when you repeat the same lesson many times, you will become bored. Then, what happens for brain waves? Do some brain waves change? To clarify that point, we measured the electroencephalogram(EEG) of the learners during their repeating the same lesson of the RIM. We also ask them to raise their hands when they felt bored. Time-frequency analysis using fast Fourier transformation of their EEG' s showed that the powers of a(8-12 Hz), 6(8-30 Hz), and y(30-50 Hz) waves at first kept constant and decreased after some while during the lesson. After the decrease in the EEG power the subjects raised their hands. On the other hand, the power of 0 wave(4-8 Hz) did not change. These results suggest that the decrease in the powers of a, 6, and y waves will be the sign for the subject' s boredom.
