The Effects of Mandarin Chinese Lexical Tones in Sound–Shape and Sound–Size Correspondences

Abstract

Abstract Crossmodal correspondences refer to when specific domains of features in different sensory modalities are mapped. We investigated how vowels and lexical tones drive sound–shape (rounded or angular) and sound–size (large or small) mappings among native Mandarin Chinese speakers. We used three vowels (/i/, /u/, and /a/), and each vowel was articulated in four lexical tones. In the sound–shape matching, the tendency to match the rounded shape was decreased in the following order: /u/, /i/, and /a/. Tone 2 was more likely to be matched to the rounded pattern, whereas Tone 4 was more likely to be matched to the angular pattern. In the sound–size matching, /a/ was matched to the larger object more than /u/ and /i/, and Tone 2 and Tone 4 correspond to the large–small contrast. The results demonstrated that both vowels and tones play prominent roles in crossmodal correspondences, and sound–shape and sound–size mappings are heterogeneous phenomena.
