Intervention effect of color and sound cross-modal correspondence between interaction of emotion and ambient

Abstract

Since the pressure of people’s daily life and work, more and more people tend to be nervous and have negative emotions such as anxiety. In order to properly intervene in people’s emotion, introduces a method of using electroencephalogram (EEG) to evaluate the intervention effect of color and sound cross modal on emotional state. The proposed method consists of three phases: emotion elicitation, emotion intervention, and EEG monitoring. The film clips are used to induce four target emotional states: joy, fear, sadness and relaxation, and a group of music clips and ambient lights were used as intervention factors. According to the two-dimensional model of emotion is described and take the valancing as the adjusting index, the ratio of the average power spectral of the left hemisphere to the right hemisphere are calculated to represent the valence change, thus evaluating the intervention effect. The results show that synesthetic combination of music and light has a more obvious effect on negative emotion intervention, the high-pitched and fast-paced music is in particular. And also Our findings highlighting the existence of cross-modal correspondence between sounds and colors in psychology.
