舞踊作品鑑賞時における情動性自律反応 : 皮膚電気反射を中心に

Abstract

The purpose of this study was to clarify the changes in Galvanic Skin Reflex (GSR) and Heart Rate (HR) while appreciating a dance piece under various conditions and while imagining it, and to survey the time errors while imagining it. Conditions for appreciating the dance piece were as follows: I: audio and visual II: only accompaniment music (audio) III: only picture (visual) The length of the dance piece used in this study was about 10 minutes. Subjects were 12 female university students (4 performers of this piece, 4 students of the department of dance, and 4 general students), aged from 20 to 23 years. Results of the experiment were as follows: 1) In the group of performers, the rate of increase of HR was rather high under all conditions (from 16% to 34%). The group for which this rate was particularly high during imagining included not only performers but other students of the department of dance. 2) In the group of performers, there were similarities between the GSR patterns while appreciating the piece. In the group of students of the department of dance, the GSR pattern under condition I was similar to that under condition II. In the group of general students, there weren't similarities between the GSR patterns under any conditions. 3) In the case of a subject whose level of dance was advanced, the GSR pattern under condition I was similar to that during imagining. The results can be summarized by saying that the emotional autonomic response while appreciating a dance piece has something to do with experience of dancing. Similarities between the GSR patterns while appreciating and while imagining a dance piece, show that skill in dancing is significant factor.
