Emotional and autonomic responses to IAPS-based stimulation : Effects of 1/f music and white noise on electrodermal and cardiorespiratory variables during the post-stress recovery

국제정서사진체계 ( IAPS ) 를 이용한 정서 및 자율신경계 반응 연구 : 1/f 음악 및 white noise가 스트레스 회복단계에서의 피부전기반응 및 심박호흡계 반응에 미치는 영향

The special interest should be paid to the analysis of the influences of positive emotions in terms of their possible effects on the dyanmics of autonomic. recovery after the negative affective stimualtion. Taking into account emotion-specific autonomic response patterning and dissociation of parameters of autonomic arousal during experience of both positive and negative emotional states, this problem seems a challenging one. In present study several autonomic parameters were analyzed altogether, namely inedices of electrodermal activity, heart rate and respitation rate during consecutive combination or both IAPS-based visual affective and auditory stimulation. The aim of the study was analysis of patterns of electrodermal and cardiorespiratory responses during emotional states evoked by negative affective visual stimulation followed by positive or neutral auditory one with intention to identify if the latter is able to facilitate post-stress recovery and enhance restoration of pre-arousal levels. The main orientation was dirdcted towards the further application of experimentally induced comfort emotions for dampening the negative consequences of exposure to stressful stimuli.
