Speech Prosody and Reading Comprehension in Chinese–English Bilingual Children: The Mediating Role of Syntactic Awareness

Purpose: Although children's prosodic sensitivity links with their reading comprehension, the factors affecting this link remain unclear. By simultaneously measuring first language (L1) Chinese and second language (L2) English prosodic sensitivity and reading comprehension, this study examined the mediating role of syntactic awareness on prosody–reading comprehension among Hong Kong Chinese–English bilingual children. Method: A group of 227 Hong Kong Chinese–English bilingual fourth graders completed L1 and L2 prosodic sensitivity (Cantonese lexical tone awareness and English prosodic sensitivity), syntactic awareness, and reading comprehension and control measures of cognitive (nonverbal IQ, short-term memory, and working memory), metalinguistic (phonological awareness and morphological awareness), linguistic (vocabulary knowledge), and word reading skills. Results: The within-language analyses showed a partial mediation effect of Chinese syntactic awareness on the relation between Cantonese lexical tone awareness and Chinese reading comprehension, but a full mediation effect of English syntactic awareness on the relation between English prosodic sensitivity and English reading comprehension. The cross-language analyses revealed a significant direct effect of Cantonese lexical tone awareness on English reading comprehension and a significant indirect effect of English prosodic sensitivity on Chinese reading comprehension via Chinese syntactic awareness. Conclusion: These findings suggest that, despite the language-independent mediating role of syntactic awareness in bridging prosody and reading comprehension, the degree of this mediation is shaped by language-specific prosody and its relations with other linguistic structures, including semantics.
