Emotions are usually perceived by multimodal cues for human communications; in recent years, emotions have been studied from the perspective of dimensional approaches. Investigation of audio and video cues to emotion perception in terms of categories of emotion has been relatively extensively conducted, but the contribution of audio and video cues to emotion perception in dimensional space is relatively under-investigated, especially in Mandarin Chinese. In this present study, three psychoacoustic experiments were conducted to investigate the contributions of audio, visual, and audio-visual modalities to emotional perception in the valence and arousal space. Audio-only, video-only, and audio-video modalities were presented to native Chinese subjects with normal hearing and vision for perceptual ratings of emotion in the valence and arousal dimensions. Results suggested that (1) different modalities contribute differently to perceiving valence and arousal dimensions; (2) compared to video-only modality, audio-only modality generally decreases arousal and valence at lower levels, and increases arousal and valence at higher levels; (3) the video-only modality plays an important role in separating anger and happiness emotions in the valence space.
