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.

This study examined whether syntactic awareness was related to reading comprehension difficulties in either first language (L1) Chinese or second language (L2) English, or both, among Hong Kong Chinese-English bilingual children. Parallel L1 and L2 metalinguistic and reading measures, including syntactic word-order, morphological awareness, phonological awareness, vocabulary, word reading, reading comprehension, and cognitive measures of nonverbal intelligence and working memory, were administered to 224 fourth-graders. Five groups of comprehenders were identified using a regression approach: (1) 12 poor in Chinese-only (PC), (2) 18 poor in English-only (PE), (3) six poor in both Chinese and English (PB), (4) 14 average in both Chinese and English (AB), and (5) seven good in both (GB). The results of multivariate analyses of covariance showed that (1) the PB group performed worse than the AB and GB groups in both L1 Chinese and L2 English syntactic awareness; (2) the PC and PE groups performed worse than the AB and GB groups in Chinese syntactic awareness; (3) the PE group had lower performance than the PC, AB, and GB groups in English syntactic awareness; and (4) no significant group difference was found in L2 morphological awareness or vocabulary across both languages. By suggesting that weakness in syntactic awareness can serve as a universal indicator for identifying poor comprehenders in either or both L1 Chinese and L2 English among Hong Kong Chinese-English bilingual children, these findings demonstrate the fundamental role of syntactic awareness in bilingual reading comprehension., (© 2022.

This study examined whether, and if so how, L1 and L2 segmental and suprasegmental phonological awareness is longitudinally related to L1 and L2 reading comprehension difficulties among Hong Kong Chinese-English bilingual children. Using a regression approach, we identified five types of comprehenders, i.e., 11 poor-Chinese/average-English comprehenders, 19 poor-English/average-Chinese comprehenders, six poor-Chinese/poor-English comprehenders, 12 average-Chinese/average-English comprehenders, and seven good-Chinese/good-English comprehenders among 223 Grade 4 Chinese-English bilingual children who were comparable in age, nonverbal IQ, and word reading, but differed in reading comprehension. These children were compared retrospectively on segmental and suprasegmental phonological awareness in both Chinese and English for three consecutive years from Grade 2 to Grade 4. The results revealed that only Cantonese lexical tone awareness distinguished poor comprehenders from typically developing comprehenders. Specifically, the poor-English/average-Chinese comprehenders performed worse than the average-Chinese/average-English and good-Chinese/good-English comprehenders in Grades 4 and 3, but not in Grade 2; and the poor-Chinese/average-English comprehenders performed worse than the good-Chinese/good-English comprehenders in Grades 4 and 3, but not in Grade 2. These findings suggest that suprasegmental phonological awareness, especially Cantonese lexical tone awareness, is critical for both Chinese and English reading comprehension development among Hong Kong bilingual children.
