Abstract

In this paper, we analyzed the effects of musical stimuli on humans in performing mathematical tasks through EEG measurements. The musical stimuli were divided into preferred music and non-preferred music, and mathematical tasks were divided into memorization task and procedure task. The data measured in the EEG experiments was divided into frequency bands of Theta, SMR, and Mid-beta because of the concentration. In our results, preferred music causes more positive emotional response than no music and non-preferred music regardless of the type of mathematical task.

본 논문에서는 수학적 과제 유형에 따라 음악적 자극이 인간에게 미치는 영향을 뇌파 측정을 통해 분석하였다. 음악적 자극은 선호 음악과 비선호 음악, 수학적 과제는 암기형과 절차형의 과제로 구분하여 실험을 수행하였다. 뇌파 실험에서 계측한 데이터를 인간의 집중과 관련이 있는 세타파, SMR파 및 중간베타파로 구분하여 상대 파워 스펙트럼 분석을 통해 비교하였다. 본 논문의 결과에서는 수학적 과제의 유형과 관계없이 음악적 자극이 주어진 상황 중 선호하는 음악이 주어졌을 때의 파워가 더 높게 관측되었고, 선호하는 음악이 무음악과 비선호 음악이 주어진 상황보다 과제 해결 시 긍정적인 정서 반응을 유발하는 것으로 나타났다.
