목적: 정량화된 뇌파, 감성 반응 및 성별 간 도출된 뇌파 데이터를 이용하여 컬러의 효과를 객관화시키고, 감성 반응을 색채 조절 중심리적 효과와 연관 지어 다양한 분야에 활용할 수 있도록 연구하고자 한다. 이 결과를 통하여 색자극에 의한 인지반응이 사람의 뇌와 감정조절에 미치는 영향을 파악하고자 한다. 방법: 20대 남녀를 대상으로 5가지 기본 색자극에 의한 뇌파와 감성반응을 평가하였다. 뇌파는 바탕뇌파의 상대 뇌파파워 차이의 비율인 뇌파변동계수(coefficient of variation for the brainwave, CVB)로 분석하였다. 5가지의 색은 먼셀의 표기법과 RGB값으로 표기하였다. 감성반응은 10쌍의 형용사를 제시하여 선호도(PI), 평균선호도(API), 호감도(favorability)를 평가하였다. 뇌파와 감성평가에 대한 통계분석은 SPSS를 사용하여 반복분산분석을 실시하였다. 결과: 5가지색상자극에 대한 뇌파 반응은 남녀 모두 R, P의 자극에서 집중과 각성반응이 컸다. 이완되고 편안하게 느끼는 색상은 남녀 모두 Y 와 G의 자극이었다. 색상별 부분적으로 남녀의 감성은 차이가 있었으나 대체적으로 비슷한 반응이었다. 컬러에 대한 호감도는 남녀모두 R이 높았고 Y와 P에 대한 호감도가 동일하게 높았다. 호감도가 높은 R컬러에 대한 집중과 각성의 β, γ파가 남녀 모두 크게 활성되었다. 남녀의 반응이 난색의 자극에서 각성이 되었고 한색의 경우 편안함을 느끼는 것으로 뇌파반응과 감성반응을 통하여 도출되었다. 남녀간 뇌파와 감성 결과는 비슷하게 도출되었고 컬러자극에 의한 뇌파와 감성은 민감하게 유의미하게 작용되었다. 결론: 정량화된 컬러를 바탕으로 한 뇌파와 감성 반응 결과는 다양한 분야에서 컬러를 활용하는 데 적용할 수 있을 것으로 파악된다. 이러한 결과를 활용하면 색 인식이 사람의 뇌와 감정 조절에 밀접하게 영향을 미칠 수 있을 것으로 사료된다.
Abstract
Purpose: The goal is to use quantified EEG and emotional responses to objectively assess the effects of color using gender-specific EEG data, as well as to analyze emotional responses concerning the psychological effects of color modulation. This study intends to apply these findings in various fields. Through this, we hope to better understand how color stimuli affect cognitive responses, brain activity, and emotional regulation. Methods: In this study, we evaluated the EEG and emotional responses to five basic color stimuli in male and females in their 20s. EEG analysis was performed using the Coefficient of Variation for the Brainwaves (CVBs), which is the ratio of the relative brainwave power difference to the baseline brainwave. The five colors were specified using the Munsell notation and RGB values. Emotional responses were evaluated using 10 pairs of adjectives to calculate the preference index(PI), average preference index(API), and favorability. The EEG and emotional evaluations were statistically analyzed using repeated-measures ANOVA in SPSS 22. Results: The EEG responses to the five-color stimuli revealed that both male and female experienced increased concentration and arousal with the red (R) and purple (P) stimuli. Colors yellow (Y) and green (G) caused relaxation and comfort in both genders. While male and females had different emotional responses to each color, the reactions were generally similar. Both male and females preferred the color R, while Y and P were equally popular. Color R significantly activated β and γ waves associated with concentration and arousal in both genders. Warm colors were found to elicit arousal, while cool colors induced feelings of comfort, as evidenced by EEG and emotional responses. The findings showed that EEG and emotional responses to color stimuli were similar across genders and that color had a significant and meaningful impact on brainwaves and emotions. Conclusion: The quantified findings of color-based brainwaves and emotional responses can be applied to various fields that use colors. By leveraging these findings, color perception is expected to have a strong influence on human brain activity and emotional regulation.
