Audiovisual materials are presented to subjects. The degrees of the mental states with strong emotion and the kinds of mental states are experimentally obtained. The experimental results show that different types of emotion were evoked by presenting audiovisual materials. The tendency of arousing the mental states with strong emotion is examined from the tendency of audiovisual materials used in the experiment.
