초록

본 연구의 목적은 가상현실 볼링이 정서에 미치는 영향을 연구하기 위함이다. 본 실험에 참여한 16명의 피험자는 볼링 경력 3년, 나이는 26-35세, 평균나이 29.6세의 볼러들로 구성하였다. 피험자들이 볼링을 다섯 게임 하는 동안 전두엽의 뇌파를 측정하였으며, 게임이 끝난 후 곧바로 시각상사척도를 사용해 게임 후의 정서를 측정하였다. 뇌파측정부위는 전전두엽, 전두엽, 외측 전두엽이었다. 자료 분석은 전두엽의 알파파에 대해 일원분산분석을 실시하였다. 종속변수는 알파파워 값이다. 연구결과 스트라이크를 쳤을 때는 시각사상척도 값이 스페어나 스페어 처리를 처리했을 때보다 높게 나타났다. 또한 스페어를 처리했을 때는 스페어 미스보다 시각사상척도 값이 높게 나타났다. 대뇌 반구 비대칭 점수와 관련해선 다음과 같은 결과를 얻었다. 좌측 전두엽의 알파파는 스트라이크와 스페어를 처리했을 때 활성화되는 것으로 나타났다. 한편 스페어 미스를 했을 때는 우측 전두엽의 알파파가 활성화되었다. 결론적으로 이 연구는 경쟁에서 성취 또는 성공을 했을 때 긍정적인 정서가 나타나고, 반대로 실패했을 경우에는 부정적인 정서가 나타난다는 것을 보여주었다. 또한 이 연구는 경기 중에 발생하는 수행의 결과가 선수의 정서에 직접적으로 영향을 미친다는 것을 신경생리학적으로 입증해 주었다.

The purpose of this study was to investigate the effects of virtual reality bowling on emotional changes using EEG (Electroencephalogram). Sixteen bowling players who have at least three years of experiences in bowling participated in this study. Their aged ranged from 26 to 35 years old with a mean age of 29.6 years. The frontal lobes (Fp2-Fp1, F4-F3, F8-F7) of each player were measured while subjects were performing five games of bowling. And after performing every frame, their emotion was measured immediately with Visual Analogue Scale. The data were analyzed by one-way analysis of variance to test differences in the alpha value of each region of the frontal lobes. The dependent variable is the alpha power of the cerebral asymmetry. The results showed that players who scored a strike showed higher VAS values than those who missed the spares or cleared the spares; those who cleared spares showed higher VAS values than those who missed spares In addition, with respect to frontal R-L asymmetry score, the alpha-wave of the left frontal lobe was activated when scoring a strike and clearing spares and the alpha-wave of the right frontal lobe was activated when missing spares. In conclusion, the results of this study demonstrated that success or achievement in competition gives rise to positive emotions and vice versa. This study neurophysiologically proved that performance outcomes during a competition directly influence players' emotion and brain waves.
