基于定量脑电图的音乐和灯光颜色对情绪的影响 <sup>*</sup>
摘要
<p id="C2">Numerous studies showed that music mode and lamplight color impact audiences’ emotions. It’s generally accepted that major-mode, Chinese ancient Gong-mode and red light are associated with excited and vigorous emotions. Minor-mode, Chinese ancient Yu-mode, and blue and green light have characteristics of calm and contented emotion. Furthermore, recent studies indicated that both music modes and lamplight colors induce emotional changes. Beyond exploring the effects of two emotional stimuli on emotional induction, this study validated the consistency of emotional information of the stimuli with the two emotional stimulations. <p id="C2-1">Participants (total 41) were divided into two groups randomly to take part in different experiments. In the first experiment, three lamplight colors and four music modes were stimulated on 21 participants to study their subjective perception. Simultaneously, the EEG data of participants were collected. In the second experiment, dual-factor stimulations with three lamplight colors and four music modes were applied on 20 participants to evaluate their subjective perception, with the EEG data collected. Before each experiment, every participant was asked to execute two moderately difficult calculations to clear their minds. The average frequency band power of EEG was calculated and the subjective emotional evaluation was done at the end of each experiment. <p id="C2-123">The first experiment showed that major-mode and Chinese ancient Gong-mode tunes were positive emotional stimuli; on the contrary, minor-mode and Chinese ancient Yu-mode tunes were negative. The arousal degree of tri-color light (red, blue, and green) is greater than the minor-mode tune. The second experiment revealed that red lamplight color inhibited the effect of tune mode on emotional potency. Despite the fact that blue and green lamplight colors promoted the effect of Western tune mode, they inhibited that of Oriental tune mode. The study concluded as be
