Abstract

The purpose of this research was to confirm that prefrontal neurofeedback training has an impact on adolescents. The objective of this study was to prove its scientific effect through experimentation. The effect of the training was measured by the difference in neuro?frequencies before and after the training. For this research, an experimental group and a control group, each with 22 students in J High School located in the city of S participated in this study. From May to July 2019, the training was conducted three times a week and for 30 minutes per session. The neuro?frequency data collected were analyzed through the methods of F.F.T. The resulting changes from the neurofeedback training for each group were analyzed by T-Tests. The result of the study is as follows; Neurofeedback training has had a positive effect on adolescent attention and sleep. In conclusion, the environmental and educational factors also play an important role. As the interaction of the latter two factors yield an individual's unique brain structure and functionality, the impact of the neurofeedback training is important on adolescents. The derivation of the above results by utilizing scientific and objective methods reemphasizes the importance of this study.

이 연구는 전전두엽 뉴로피드백 훈련이 청소년의 주의력과 수면에 미치는 영향을 검증할 목적으로 이루어졌다. 청소년의 삶의 질과 학습에 직결되는 주의력과 수면에 대한 다양한 연구 방법 가운데 뉴로피드백 훈련 효과가 과학적으로 입증될 수 있는지 실제 실험을 통하여 밝히는 데 목적이 있다. 연구를 위해 S시 J여자 고등학교에서 실험군 22명, 대조군 22명으로 구분하여 실험군에게 뉴로피드백 훈련을 실시하였다. 2019년 3월부터 7월 첫 주까지 주3회, 훈시간은 30분씩 하였다. 수집한 뇌파데이터는 선형분석법을 사용하여 고속퓨리에 변환을 통한 주파수계열파워 스펙트럼 분석법을 이용하여 통계처리하였다. 뉴로피드백 훈련 전과 훈련 후의 집단 간 변화 차이는 T-test를 사용하였다. 연구 결과는 전전두엽 뉴로피드백 훈련이 청소년의 주의력을 향상시키고, 수면을 개선시키는 데 효과가 있음을 확인할 수 있었다. 결론적으로 환경적요소와 교육적 요소가 중요한 역할을 한다. 두 요인의 상호작용은 개인의 독특한 뇌 구조와 기능을 낳기 때문에 뉴로피드백 훈련의 영향은 청소년들에게 중요하다. 본 연구에서는 과학적이고 객관적인 방법을 활용하여 결과를 도출하였다는 것이 중요함을 다시 강조한다.
