Abstract
본 연구는 심리적 안정화에 효과적인 영상 개발을 위해 영상자극에 따른 정서생리적 반응 지표 차이를 검증하였다. 12명의 대학(원)생을 단일종류 영상 집단과 혼합종류 영상 집단에 무선할당하여 처치를 실시하고, 뇌파와 심박수, 정서, 상태불안을 측정하여 통계 검증하였다. 그 결과, 단일경관 처치에 따라 정적정서 및 부적정서 총합, 개별단어 중 흥미진진한, 과민한, 원기왕성한, 신경질적인, 주의깊은, 열정적인, 활기찬이 유의한 차이를 나타냈다. 뇌파의 경우, Alpha파, Slow Alpha파, High Beta파, Gamma파가 증가하고, Theta파, Ratio Alpha to High Beta파는 감소하였다. 이로써 단일 자연경관 영상으로 긍정정서가 고양되고, 기억의 통합 및 주의와 같은 인지적 기능 향상을 확인하였다. 혼합경관집단에서는 정적정서 및 부적정서 총합, 개별단어 중 흥미진진한, 신경질적인, 적대적인, 두려운, 그리고 상태불안이 유의한 차이가 있었다. 뇌파는 Slow Alpha파, Ratio Alpha to High Beta가 감소하였고, Fast Alpha, Low Beta, Mid Beta, High Beta, Slow Theta파는 증가하였다. 이로써 혼합경관 영상이내면으로의 집중과 부적정서 감소에 효과가 있음을 확인하였다. 심박수는 변화가 유의하지 않았다. 이후 본 연구의 의의와 제한점, 후속 연구에 대한 시사점을 논하였다.The purpose of this study was to develop a video intervention tool for psychological stabilization by verifying differences in psychophysiological indicators (positive affect, negative affect, state anxiety, EEG, HRV) in response to video stimulation. Twelve university students were randomly assigned to the group “Only” where participants watched single-typed video stimuli or to the group “Mix” where they watched mixed-typed video stimuli. Before and after each video stimulus, the participants completed the PANAS scale and STAI-X scale, and HRV and EEG was recorded during the video stimulation. For the group “Only”, a total score of positive and negative affect, an individual score of interested , irritable , inspired , nervous, attentive , enthusiastic , and active , and the brain index such as ‘RT’ at Fp1, Fp2, and T5, ‘RA’ and ‘RSA’ at F7, ‘RG’ at Fp1, Fp2 and T3, ‘RHB’ at C3 and C4, ‘RAHB’ at Fz showed significant difference between video stimuli. For the group “Mix”, significant differences were found in a total score of positive and negative affect, interested, nervous, hostile, afraid, state anxiety, and brain index such as ‘RSA’ at P3 and Fz, ‘RHB’ and ‘RAHB’ at P3, ‘RFA’ at F8 and O2, ‘RLB’ at F8, F4 and P4, ‘RMB’ at Fp2, ‘RST’ at Cz, and asymmetry between P3 and P4. No significant difference was found for HRV.
