Abstract

In this paper, we measured and analyzed the EEG signals related to the relativity between musical stimuli and human concentration for memorization. In our experiments, the subjects carried out the tasks related to human memorization exposing to musical stimuli and the tasks are to memorize the english words. We used two kinds of musical stimuli, one is a sedative tendency music and the other is a stimulative tendency music. We presented the results that are analyzed as the EEG signals by frequency bands, respectively.

본 논문에서는 음악적 자극이 인간의 기억에 관련된 집중력에 미치는 영향을 조사하기 위하여 인간의 뇌파를 계측 및 분석하였다. 뇌파 실험에서는 음악적 자극과 함께 기억 관련 과제를 수행하게 하였는데, 기억 관련 과제로는 영어단어를 암기하는 것을 선정하였다. 음악적 자극은 진정성향 및 자극성향의 음악으로 나누어 제시하였고, 피험자의 뇌파는 주파수 대역에 따라 나누어 분석한 결과를 각각 제시하였다.
