Sensorimotor norms for Chinese nouns and their relationship with orthographic and semantic variables

Sensorimotor information is vital to the conceptual representation of our knowledge system. This study collects perceptual and action ratings for 664 disyllabic nouns among 438 native speakers and creates the first and largest dataset of sensorimotor norms for nouns in Chinese. Using aggregated semantic covariates, including concreteness ratings from a concreteness rating study, as well as the reaction times and error rates from a lexical decision study, our current work demonstrates the strengths of sensory modalities and action effectors in Chinese nouns and explores the contributions of embodied experiences in reflecting orthographic representations and semantic processing in the Chinese language. This study contributes valuable data sources to the study of Chinese lexical processing and highlights the importance of sensorimotor information and embodied manifestations in the semantic representations of concepts. Our results also support the language universal that orthographic awareness in lexical processing and reading supersedes phonological awareness.
