The emotion code in sensory modalities : an investigation of the relationship between sensorimotor dimensions and emotional valence-arousal

Abstract

Human sensations and emotions are our primary embodied feelings in experiencing the outside world. The two systems are closely intertwined and jointly contribute to cognitive processes such as language use. However, how the two systems interact as manifested in our languages is still not well understood. This paper utilizes perceptual strengths and affective ratings to delve into the interaction between specific sensory modalities and emotional valence-arousal in Chinese. We found that smell and interoception, considered the two sensations directly linked to emotional processing, are more emotional and can elicit higher arousal levels than words associated with other senses. This study demonstrates the relevance and significance of the relationship between sensorimotor and affective information. It further sheds light on the embodied effect and associated emotional implications in the Chinese language.
