Tone matters for Cantonese-English bilingual children's English word reading development: A unified model of phonological transfer

Cognitive Flexibility Moderates the Predictive Effect of Phonological Awareness on Focus Structures in Chinese Preschool Children

Focus structures, a complex aspect of information structure in language, have garnered significant attention in psycholinguistics. The question of whether Chinese preschoolers aged 4-6 years possess the ability to process focus structures in oral communication, and how cognitive factors influence this ability, remains a research focal point. To address this, we recruited 100 Chinese preschoolers aged 4-6 years as participants in our study. This study manipulated the positions of focus particles in sentences to investigate the impact of phonological awareness on young children's comprehension of focus structures. Additionally, we examined the mediating roles of cognitive flexibility and inhibitory control. Our findings indicate the following: (1) phonological awareness positively predicted the accuracy of focus structural processing; (2) inhibitory control did not significantly predict the accuracy of focus structural processing; and (3) cognitive flexibility partially mediated the relationship between phonological awareness and focus structural comprehension. These results confirmed the predictive effect of cognitive flexibility on children's comprehension of focus structures. Moreover, they demonstrate that young children's phonological awareness can predict their focus structure comprehension ability through the mediating role of cognitive flexibility. This suggests that children's cognitive flexibility can aid in understanding sentences with focus structures.

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.

Prosodic Transfer in English Literacy Skills among Chinese Elementary-Age Students: Controlling for Non-Verbal Intelligence

Building upon the prosodic transfer hypothesis, the current study aims to examine the intermediary effect of English stress on the relation between Chinese lexical tone awareness and English word-level literacy (reading and spelling) as well as the moderating effect of English oral vocabulary proficiency on the cross-linguistic association. Grade 4 Chinese learners of English (N = 224) participated in this study and were assessed for their tone and stress sensitivity, English oral vocabulary, English word reading, and English word spelling. Mediated multivariate analyses with moderation were used to explore: (1) whether the influence of lexical tone perception on L2 word reading and spelling was mediated by English stress as posited in the prosodic transfer hypothesis; (2) whether the effects of tone on English word reading and spelling performance varied as a function of oral vocabulary levels. The findings revealed a direct positive relationship between Chinese tone and English word reading and spelling, and the relationship was mediated by English stress awareness. Furthermore, the direct pathway from tone to English word-level literacy skills were moderated by oral vocabulary and the relationship between tone and English word-level skills became stronger as oral vocabulary levels increased; however, such strength reached a plateau among children without adequate oral vocabulary skills. These findings suggest the necessity to incorporate word spelling as an outcome in the cross-suprasegmental phonological transfer models of early literacy development. Additionally, the current study endorses the complexity of cross-language prosodic transfer. It points to a precise threshold for sufficient L2 oral vocabulary skills to enable tone transfer in English word-level literacy attainment.

Bibliometric analysis of the literature on phonological awareness in bilingual children

ABSTRACT Purpose: to characterize the profile of scientific production in the international literature on phonological awareness in bilingual children between 2011 and 2020. Methods: a bibliometric analysis was made with the search for articles in ERIC, LILACS, MEDLINE, and SciELO databases, using descriptors in English. The articles were selected based on the eligibility criteria, by reading the titles, then reading the abstracts, and lastly, reading the full-text articles. Results: a total of 1,167 articles were analyzed, 1,152 of which were excluded for not meeting the inclusion criteria. Hence, 15 articles were selected for full-text reading and bibliometric analysis. The United States was the country with most publications, followed by Brazil, Singapore, and China. The approach of the studies was predominantly quantitative, followed by qualitative; the most common type of study was cross-sectional, with samples of more than 100 participants. Conclusion: there was a greater number of publications in the last 3 years, most of them cross-sectional ones, presenting better phonological awareness performance among bilinguals, with positive results in reading.

Auditory Processing of Non-speech Stimuli by Children in Dual-Language Immersion Programs

Perception of low-level auditory cues such as frequency modulation (FM) and rise time (RT) is crucial for development of phonemic representations, segmentation of word boundaries, and attunement to prosodic patterns in language. While learning an additional language, children may develop an increased sensitivity to these cues to extract relevant information from multiple types of linguistic input. Performance on these auditory processing tasks such as FM and RT by children learning another language is, however, unknown. Here we examine 92 English-speaking 7-8-year-olds in the U.S. and their performance in FM and RT perceptual tasks at the end of their second year in Cantonese or Spanish dual-language immersion compared to children in general English education programs. Results demonstrate that children in immersion programs have greater sensitivity to FM, but not RT, controlling for various factors. The immersion program students were also observed to have better phonological awareness performance. However, individual differences in FM sensitivity were not associated with phonological awareness, a pattern typically observed in monolinguals. These preliminary findings suggest a possible impact of formal language immersion on low-level auditory processing. Additional research is warranted to understand causal relationships and ultimate impact on language skills in multilinguals.

Suprasegmental but not segmental phonological awareness matters in understanding bilingual reading comprehension difficulties in Chinese and English: a 3-year longitudinal study

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.

From Cantonese Lexical Tone Awareness to Second Language English Vocabulary: Cross-Language Mediation by Segmental Phonological Awareness

Purpose Cantonese lexical tone awareness is closely associated with 1st language Cantonese vocabulary knowledge, but its role in 2nd language English vocabulary knowledge was unclear. We addressed this issue by investigating whether and, if so, how Cantonese lexical tone awareness contributes to English expressive vocabulary knowledge in Hong Kong Cantonese-English bilingual children. Method A sample of 112 Hong Kong Cantonese-English bilingual 2nd graders were tested on Cantonese lexical tone awareness, English lexical stress sensitivity, Cantonese- English segmental phonological awareness, and both Cantonese and English expressive vocabulary knowledge. Results Structural equation modeling analyses revealed that Cantonese lexical tone awareness contributed indirectly to English expressive vocabulary knowledge through English lexical stress sensitivity and Cantonese-English segmental phonological awareness. Conclusion These results demonstrate the role of Cantonese lexical tone awareness in Cantonese-English bilingual children's English vocabulary knowledge. This also underscores the importance of 1st language suprasegmental phonological awareness in 2nd language expressive vocabulary knowledge.

Bidirectional Cross-Linguistic Association of Phonological Skills and Reading Comprehension: Evidence From Hong Kong Chinese-English Bilingual Readers

This study examined the roles of first-language (L1) Chinese and second-language (L2) English phonological skills in English and Chinese reading comprehension, respectively, and their association with reading comprehension difficulties among Hong Kong Chinese-English bilingual children. We tested 258 second graders on nonverbal intelligence, working memory, phonological skills, word reading, and reading comprehension, in both Chinese and English. Structural equation modeling analyses revealed that Chinese phonological skills contributed to English reading comprehension both directly and indirectly, through the mediation of English phonological skills and English word reading. In contrast, English phonological skills contributed only indirectly to Chinese reading comprehension through L1 Chinese phonological and word reading skills. Furthermore, poor Chinese readers, poor English readers, and poor readers in both Chinese and English exhibited lower levels of lexical tone awareness than average readers, even after controlling for nonverbal intelligence, word reading, and working memory. Poor Chinese readers outperformed poor English readers and poor readers in both Chinese and English on Chinese segmental phonological awareness, and their performance was comparable to average readers. These findings suggest that both suprasegmental and segmental phonological skills are critical to the development of reading comprehension across L1 Chinese and L2 English in Hong Kong Chinese-English bilingual children.

From Lexical Tone to Lexical Stress: A Cross-Language Mediation Model for Cantonese Children Learning English as a Second Language

This study investigated how Cantonese lexical tone sensitivity contributed to English lexical stress sensitivity among Cantonese children who learned English as a second language (ESL). Five-hundred-and-sixteen second-to-third grade Cantonese ESL children were tested on their Cantonese lexical tone sensitivity, English lexical stress sensitivity, general auditory sensitivity, and working memory. Structural equation modeling revealed that Cantonese lexical tone sensitivity contributed to English lexical stress sensitivity both directly, and indirectly through the mediation of general auditory sensitivity, in which the direct pathway had a larger relative contribution to English lexical stress sensitivity than the indirect pathway. These results suggest that the tone-stress association might be accounted for by joint phonological and acoustic processes that underlie lexical tone and lexical stress perception.
