ワーキングメモリ能力と音楽的スキルの関係に関する検討

抄録

In previous studies, it was shown that the working memory of musician renews faster and has larger capacity compared with it of non-musician. However, the kind of musical skill related working memory was not clear. In this study, we investigated the relationship between several musical skills and working memory ability measured by EEG. As a result, it was shown that the significant positive correlation between P300 amplitude evoked by sound stimulus and absolute pitch for chord. It was also shown that the significant negative correlation between P300 peak latency evoked by image stimulus and sing at sight. On the other hand, the significant positive correlation between P300 peak latency evoked by image stimulus and relative pitch for chord was shown. This result contradicts former two results. This contradiction may be caused by small number of subjects. As a future study, we plan to apply more subjects.
