초록
본 연구는 뉴로피드백을 통한 전두엽 뇌파 비대칭의 변화가 접근-회피 동기 반응에 미치는 영향을 알아보기 위해 수행되었다. 17명의 오른손잡이 피험자들은 준무선적으로 LEFT 집단(좌측 전두엽의 활동을 증가시키는 집단)과 RIGHT 집단(우측 전두엽의 활동을 증가시키는 집단)으로 할당되었으며, 3일간 총 15회기(4분씩 5회기/1일)에 걸쳐 뉴로피드백을 수행하였다. 피험자들은 뉴로피드백 실시 전후에BDI-II, BIS/BAS 척도(Behavioral Inhibition System/ Behavioral Activation System scale), 정서 필름(긍정적인 정서, 부정적인 정서, 중성적인 정서)에 대한 정서 평정을 실시하였다. 뉴로피드백 훈련결과 LEFT 집단은 우반구 알파파 활동이 증가되었으며 RIGHT 집단은 좌반구 알파파 활동이 증가되었다. 동기의 측정결과 LEFT 집단은 RIGHT 집단에 비해 BAS 점수가 향상되었으며, 정서필름에 대한 반응에서는 뚜렷한 정서가를 가진 자극에 대한 반응성이 증가하였다. 이러한 결과는 LEFT 집단의 접근 동기 경향성이 증가하였음을 시사하며, 전두엽 뇌파 비대칭이 동기 방향과 관련이 있다는 것을 보여준다. 마지막으로 본 연구의 임상적 의의와 제한점, 후속 연구에 대한 시사점을 논의하였다.
Abstract
The purpose of this study was to examine the effect of manipulating the frontal EEG asymmetry by neuro-feedback on the approach/withdrawal motivational response, and to ascertain the frontal asymmetrical activity associated with the motivation direction. 17 right-handed participants were partially randomly assigned to receive neurofeedback training, and this training was designed to increase the left frontal activity relative to the right frontal activity (the LEFT group) or they received training in the opposite direction (the RIGHT group). 3 consecutive days of neurofeedback training was done, and this was consisted of 5 4-min sessions (a total of 15 sessions). All the participants completed the BDI-II and, BIS/BAS and the affective rating scale for the positive, negative and neutral emotionally evocative film clips at the first and last day. As a result, the individuals in the LEFT group increase their left frontal activity relative to the right frontal activity, and the and individuals in the RIGHT group increase their right frontal activity relative to their left frontal activity. Consequently, the LEFT group reported a higher BAS score and stronger affect in response to obvious emotional film clips than did the RIGHT group. There was no significant relationship between the groups and the BIS score. These results suggest frontal asymmetrical activity is related to the motivational direction and it is not related to the affective valence.
