| Research Abstract |
The present study investigated the time-course of subjective emotional intensity using psychophysiological methods. Firstly equipment for rating of subjective emotional intensity was developed. When it was measured using this, it was found that emotional intensity emerged rapidly, within 10 s of the emotional stimulus presentation. Emotional intensity was gradually decreased afterwards even if the emotional stimulus was presented. With evocation of emotion, measurement of electroencephalogram partially supported the frontal lateral model of emotion and frequency fluctuation model of frontal alpha wave.
