Do First Language, Word Frequency and Input Matter in Bilingual’s Language Acquisition?

The acquisition of morphosyntactic features, such as third-person singular (3SG) inflection, is a critical aspect of language development. While much research has focused on monolingual children’s acquisition of 3SG inflection, less is known about how bilingual children navigate this process, particularly those from non-inflectional first language (L1) backgrounds. Furthermore, two well established characteristics found in other bilingual groups: word frequency and L1 transfer are still remain unclear in the acquisition of 3SG inflection in Chinese-English bilingual groups. Addressing these gaps are crucial for understanding the unique challenges bilingual children face and the factors influencing their acquisition of English morphosyntatic feature. In this study, we employed corpus to analyze longitudinal naturalistic data from three Chinese-English bilingual children and one English monolingual child. We investigated the children’s use of 3SG inflection across obligatory contexts, examining the frequency of verb exposure in both parental input and a large corpus (COCA). Our results indicate that bilingual children, especially those from a non-inflectional L1 background, demonstrated delayed acquisition of 3SG inflection compared to monolingual counterparts. However, both groups showed better accuracy with high-frequency verbs, underscoring the importance of input frequency. Additionally, L1 transfer effects were evident in both monolingual children and bilingual children, with the bilingual children struggling more with verbs whose L1 lacked verb agreement. These findings suggest that both input frequency and L1 transfer play significant roles in shaping bilingual children’s acquisition of 3SG inflection. This study contributes to a deeper understanding of bilingual language development, with implications for language acquisition theory and educational practices, particularly in addressing the needs of children from diverse linguistic backgrounds.

Predictors of Chinese reading in Chinese monolingual and Chinese–English bilingual children in Mainland China

AbstractThere is a growing number of children learning to read in bilingual environments, yet research on the uniqueness of reading acquisition in these bilingual children, particularly L1 majority bilinguals, is limited. With a sample size of 690 4th-grade students, this study investigated predictors influencing L1 Chinese reading in Chinese–English bilingual children (n = 345) attending Chinese–English bilingual schools in mainland China and made comparisons with their monolingual counterparts (n = 345). The results of a multi-group path analysis revealed both similarities and differences between the two groups. In terms of Chinese reading comprehension, word reading and linguistic comprehension were significant predictors for both groups, but their relative importance differed. While there was no difference in the predictive power between the two predictors in the monolingual group, word reading held a greater contribution in the bilingual group. Regarding Chinese word reading, both morphological and orthographic awareness emerged as significant predictors in the monolingual group, whereas in the bilingual group, only morphological awareness was significant, and the contribution of phonological awareness was insignificant in either group. These findings underscore the distinct relationship between reading and its predictive constituents in bilingual students when compared to their monolingual counterparts.

Language Distance Moderates the Effect of a Mixed-Language Environment on New-Word Learning for 4-Year-Old Children.

As bilingual families increase, the phenomenon of language mixing among children in mixed-language environments has gradually attracted academic attention. This study aims to explore the impact of language mixing on vocabulary acquisition in bilingual children and whether language distance moderates this impact. We recruited two groups of bilingual children, Chinese-English bilinguals and Chinese-Japanese bilinguals, to learn two first-language new words in a monolingual environment and a mixed-language environment, respectively. The results showed that the participants could successfully recognize the novel words in the code-switching sentences. However, when we compared the performance of the two groups of bilingual children, we found that the gaze time proportion of the Chinese-English bilingual children under the code-switching condition was significantly higher than that of the Chinese-Japanese bilingual children, while there was no significant difference under the monolingual condition. This suggests that language mixing has an inhibitory effect on vocabulary acquisition in bilingual children and that this inhibitory effect is influenced by language distance, that is, the greater the language distance, the stronger the inhibitory effect. This study reveals the negative impact of language mixing on vocabulary acquisition in bilingual children and also implies that there may be some other influencing factors, so more research is needed on different types of bilingual children.

Neural substrates of L2-L1 transfer effects on phonological awareness in young Chinese-English bilingual children

The growing trend of bilingual education between Chinese and English has contributed to a rise in the number of early bilingual children, who were exposed to L2 prior to formal language instruction of L1. The L2-L1 transfer effect in an L1-dominant environment has been well established. However, the threshold of L2 proficiency at which such transfer manifests remains unclear. This study investigated the behavioral and neural processes involved when manipulating phonemes in an auditory phonological task to uncover the transfer effect in young bilingual children. Sixty-two first graders from elementary schools in Taiwan were recruited in this study (29 Chinese monolinguals, 33 Chinese-English bilinguals). The brain activity was measured using fNIRS (functional near-infrared spectroscopy). Bilingual children showed right lateralization to process Chinese and left lateralization to process English, which supports more on the accommodation effect within the framework of the assimilation-accommodation hypothesis. Also, compared to monolinguals, bilingual children showed more bilateral frontal activation in Chinese, potentially reflecting a mixed influence from L2-L1 transfer effects and increased cognitive load of bilingual exposure. These results elucidate the developmental adjustments in the neural substrates associated with early bilingual exposure in phonological processing, offering valuable insights into the bilingual learning process.

Syntactic and Pragmatic Functions of Chinese-English Bilingual Children’s Code-Switching

Based on the bilingual children’s and adults’ code-switching (CS) dependency treebanks, this paper investigates the syntactic features and pragmatic functions of the Chinese-English bilingual children’s CS and compares them with bilingual adults’. It is mainly found that (1) As to the bilingual children, the mixed sentences present the longest mean sentence length (MSL), followed by those of the dominant language and the weak language. Similarly, Chinese-English adults’ mixed sentences present longer MSL than monolingual Chinese and English; (2) Subjects, objects, adverbials, and attributives are four major syntactic functions. Regarding bilingual children’s CS, objects are the most frequently switched dependency relations and subjects are the least. Differently, as to bilingual adults, attributives are most frequently switched, and subjects are the least. (3) Nouns, pronouns, determiners, adjectives, adverbs, and prepositions are the top word classes involved in four major syntactic relations; (4) The adverbial dependency relations present the longest mean dependency distance (MDD), and the attributives present the shortest for both bilingual children and adults; (5) The major causes that make different MDDs are the CS peripherality, the distributions of top word classes and adjacent dependency relations; (6) Six major pragmatic functions are performed by bilingual children and adults: filling lexical gaps, emphasis or expressing the intense feelings, explaining, giving “orders” or requirements, quotation, reiteration. The results syntactically and pragmatically suggest that there exist great similarities between bilingual children’s and adults’ code-switching.

Phonological and morphological literacy skills in English and Chinese: A cross-linguistic neuroimaging comparison of Chinese-English bilingual and monolingual English children.

Over the course of literacy development, children learn to recognize word sounds and meanings in print. Yet, they do so differently across alphabetic and character-based orthographies such as English and Chinese. To uncover cross-linguistic influences on children's literacy, we asked young Chinese-English simultaneous bilinguals and English monolinguals (N = 119, ages 5-10) to complete phonological and morphological awareness (MA) literacy tasks. Children completed the tasks in the auditory modality in each of their languages during functional near-infrared spectroscopy neuroimaging. Cross-linguistically, comparisons between bilinguals' two languages revealed that the task that was more central to reading in a given orthography, such as phonological awareness (PA) in English and MA in Chinese, elicited less activation in the left inferior frontal and parietal regions. Group comparisons between bilinguals and monolinguals in English, their shared language of academic instruction, revealed that the left inferior frontal was less active during phonology but more active during morphology in bilinguals relative to monolinguals. MA skills are generally considered to have greater language specificity than PA skills. Bilingual literacy training in a skill that is maximally similar across languages, such as PA, may therefore yield greater automaticity for this skill, as reflected in the lower activation in bilinguals relative to monolinguals. This interpretation is supported by negative correlations between proficiency and brain activation. Together, these findings suggest that both the structural characteristics and literacy experiences with a given language can exert specific influences on bilingual and monolingual children's emerging brain networks for learning to read.

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

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. 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. 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. 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.

Word reading transfer in two distinct languages in reading interventions: How Chinese-English bilingual children with reading difficulties learn to read

PurposeSkills developed from literacy training in L1 are shown to transfer to reading in L2 when both languages involve an alphabetic writing system. However, transfer of literacy skills between a logographic L1 and an alphabetic L2 is less studied. This study examined whether the gain in literacy skills after an 8-week training on 1) Chinese character recognition or 2) English phonics, may generalize across the two languages in Chinese elementary students with reading disabilities. MethodsChinese-speaking students identified with reading difficulties were randomly assigned to the Chinese intervention (Chinese character orthography training), English intervention (English phonics training), and control groups. Their Chinese and English literacy skills were measured before and after the interventions. ResultsThough training on the orthography of Chinese characters significantly improved performance in Chinese word reading and Chinese orthographic awareness, our results did not provide evidence for the generalization of word-decoding skills from L1 Chinese to word reading in L2 English. However, phonics training in L2 English benefitted not only English word reading, but also cross-language word reading in L1 Chinese. ConclusionWe postulated that teaching children analytical skills in decoding words in an alphabetic writing system might likewise benefit their word decoding in a logographic script.

When Learners Read in Two Languages: Understanding Chinese-English Bilingual Readers Through Miscue Analysis

The number of Chinese-speaking students in Canadian schools is increasing dramatically. This article discusses a study in which we explored reading processes in Chinese and English through examining children’s reading in both languages. Based in a socio-psycholinguistic framework (K. Goodman, Wang, Iventosch, & Y. Goodman,2012; Kabuto, 2017) and through using miscue analysis, we examined how children apply their knowledge of language to Mandarin and English reading. This qualitative research included interviews with four Chinese-English bilingual children between grades 3 and 5 in an urban center as well as the analysis of their reading performance in both languages. From a comparative perspective, we discuss some of the similarities and differences between these two different orthographic language systems by offering syntactic comparisons of the two languages through psycholinguistic language cueing systems. We believe that knowing about how Chinese and English readers construct meaning in both languages will help English as an Additional Language (EAL) teachers, in fact all classroom teachers, to teach reading to bilingual and biliterate children.

Syntactic awareness matters: uncovering reading comprehension difficulties in Hong Kong Chinese-English bilingual children.

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 insyntactic awareness can serve asa universal indicator for identifying poor comprehenders in either or both L1Chinese and L2English among Hong Kong Chinese-Englishbilingual children, these findings demonstrate the fundamental role of syntacticawareness in bilingual reading comprehension.

Spelling as a way to classify poor Chinese-English literacy skills in Hong Kong Chinese children.

Previous work has predominantly focused on word reading in studying literacy difficulties; very little work has focused on spelling difficulty instead. The present study adopted spelling (dictation) as the criterion to classify poor literacy skills in Hong Kong Chinese-English bilingual children. We examined the cognitive-linguistic skills profiles across four groups of children with different spelling abilities. Based on performances on Chinese and English dictation (criterion = below 25% in a larger sample), four groups were identified, 21 poor spellers of Chinese (PC), 18 poor spellers of English (PE), 27 poor spellers of both languages (PB), and 30 good spellers of both scripts (GB). Measures on language-specific tests of cognitive-linguistic skills (phonological awareness, lexical decision, morphological awareness, rapid naming, and delayed copying) were included to compare the degree of deficit exhibited by each group. With age, grade, and non-verbal intelligence controlled, one-way ANCOVA results revealed that, compared to GB, PC manifested significant deficits in Chinese-delayed copying but scored similarly on all English cognitive-linguistic skills. PE and PB showed significant deficits in Chinese and English phonological awareness compared to PC; they were significantly weaker in English-delayed copying, morphological awareness, and rapid naming (RAN). The PB group was significantly slower in both Chinese and English RAN compared to GB. Findings highlight the critical role of delayed copying in distinguishing poor spellers in both Chinese and English, the importance of phonological awareness for spelling in English but not in Chinese, and the role of automaticity in bilingual spelling difficulties.

Validation of the PPVT–5 for Chinese-English bilingual learners: Application of cross-classified mixed effects model

Despite the wide use of the Peabody Picture Vocabulary Test (PPVT) in second language acquisition and bilingual studies, very few validation studies have been conducted in bilingual contexts, especially for Chinese-English bilinguals. This study was designed to evaluate the validity evidence of the newest version of the series, the PPTV-5, for Chinese-English bilingual first graders in British Columbia, Canada. Validation in this study was an exercise of identifying and explaining sources of expected and unexpected score variations. Cross-classified mixed effects models (CCMEM) were employed to evaluate multiple sources of validity evidence in terms of demographic aspects (i.e., gender, school type, home language, and immigration background), lexical features, and test design. Results showed that there was no bias or unexpected score variations due to gender, school type, and home language. Expected score variations attributed to immigration background, lexical features and test design supported the use of PPVT-5 among Chinese-Bilingual children. In conclusion, PPVT-5 is a valid tool for assessing Chinese-English bilingual children's English receptive vocabulary in Canada.

Greater Similarity Between L1 and L2's Brain Network in Adults Than in Children.

It has been documented that processing L2 and L1 engages a very similar brain network in bilingual adults. However, it is not known whether this similarity is evident in bilingual children as well or it develops with learning from children to adults. In the current study, we compared brain activation in Chinese-English bilingual children and adults during L1 and L2 processing. We found greater similarity between L1 and L2 in adults than in children, supporting the convergence hypothesis which argues that when the proficiency of L2 increases, the L2’s brain network converges to the L1’s brain network. We also found greater differences between adults and children in the brain for L2 processing than L1 processing, even though there were comparable increase in proficiency from children to adults in L1 and L2. It suggests an elongated developmental course for L2. This study provides important insights about developmental changes in the bilingual brain.

Does Early Exposure to Chinese-English Biliteracy Enhance Cognitive Skills?

Clarifying the effects of biliteracy on cognitive development is important to understanding the role of cognitive development in L2 learning. A substantial body of research has shed light on the cognitive factors contributing to biliteracy development. Yet, not much is known about the effect of the degree of exposure to biliteracy on cognitive functions. To fill this research void, we measured three categories of biliteracy skills (language, reading, and cognitive–linguistic skills in both Chinese and English) jointly and investigated the effects of biliteracy skill performance in these three categories on cognitive skills (working memory and attentional control) in Chinese L1 children who were exposed to English as L2 beginning at age 3 (“early”) or in grade 3 (“late”). In this cross-sectional study, 10 parallel Chinese and English language, reading, and cognitive–linguistic measures were administered to emerging Chinese–English bilingual children in grade 3 (n = 178) and grade 6 (n = 176). The results revealed that early exposure to Chinese–English biliteracy enhanced cognitive skills but with a cost of a slight delay in performance on Chinese L1 language skills in grade 3 (but not in grade 6). Importantly, the present findings suggest that, in addition to universal and developmental processes, the cumulative effect of early and sustained bi-scriptal exposure enhances working memory and attention in school children.

Left and Right Arcuate Fasciculi Are Uniquely Related to Word Reading Skills in Chinese-English Bilingual Children.

Whether reading in different writing systems recruits language-unique or language-universal neural processes is a long-standing debate. Many studies have shown the left arcuate fasciculus (AF) to be involved in phonological and reading processes. In contrast, little is known about the role of the right AF in reading, but some have suggested that it may play a role in visual spatial aspects of reading or the prosodic components of language. The right AF may be more important for reading in Chinese due to its logographic and tonal properties, but this hypothesis has yet to be tested. We recruited a group of Chinese-English bilingual children (8.2 to 12.0 years old) to explore the common and unique relation of reading skill in English and Chinese to fractional anisotropy (FA) in the bilateral AF. We found that both English and Chinese reading skills were positively correlated with FA in the rostral part of the left AF-direct segment. Additionally, English reading skill was positively correlated with FA in the caudal part of the left AF-direct segment, which was also positively correlated with phonological awareness. In contrast, Chinese reading skill was positively correlated with FA in certain segments of the right AF, which was positively correlated with visual spatial ability, but not tone discrimination ability. Our results suggest that there are language universal substrates of reading across languages, but that certain left AF nodes support phonological mechanisms important for reading in English, whereas certain right AF nodes support visual spatial mechanisms important for reading in Chinese.

Exploring the Genetic and Environmental Etiologies of Phonological Awareness, Morphological Awareness, and Vocabulary Among Chinese-English Bilingual Children: The Moderating Role of Second Language Instruction.

This study investigated the associations among bilingual phonological awareness, morphological awareness, and vocabulary by focusing on their genetic and environmental etiologies. It also explored the influence of family socio-economic status (SES) and language exposure amount on the genetic and environmental effects. A twin study was conducted with 349 pairs of Chinese-English bilingual twins (mean age = 7.37years). Cross-language transfer was found in phonological and morphological awareness but not in vocabulary knowledge. A common genetic overlap was found among these bilingual abilities. We also found a common shared environmental effect that may account for the cross-language transfer in phonological awareness and the associations among English abilities. SES and language exposure were significant environmental influences on bilingual phonological awareness and English vocabulary. More teaching in Chinese was related to a stronger genetic effect on Chinese morphological awareness, whereas more teaching in English was related to a stronger environmental impact on English abilities.

What's in a word? Cross-linguistic influences on Spanish-English and Chinese-English bilingual children's word reading development.

This study investigates the cross-linguistic transfer of literacy skills in Spanish-English, Chinese-English bilingual, and English monolingual children (N=283, 5-10years). Research question 1 examines English literacy and asks how phonological and morpho-semantic skills contribute to word reading as a function of children's language background. Structural equation modeling revealed contrasting bilingual effects: compared to English monolinguals, Spanish-English bilinguals relied more on phonological awareness in word reading, whereas Chinese-English bilinguals relied more on lexical knowledge. Research question 2 examines relations between bilinguals' heritage language proficiency and English literacy. Results revealed direct and indirect effects of heritage language meta-linguistic skills on English word reading. The study yields implications for reading theories and instructional practices in optimizing literacy in linguistically diverse children.

Absence of a bilingual cognitive flexibility advantage: A replication study in preschoolers.

Some studies have found a bilingual advantage in children’s executive function and some failed to find a bilingual advantage. For example, the results of a previous study by Bialystok & Martin (2004) indicated that Chinese-English bilingual preschool children outperformed English monolingual children in solving the dimensional change card sort (DCCS). The goal of our study was to replicate this study using the same dimensional change card sort task. We also tested our participants on vocabulary and digit span. Our participants were 40 English monolingual and 40 Mandarin-English bilingual children and were within the same age range as the children in Bialystok & Martin’s (2004) study. Our results showed no difference between bilinguals and monolinguals. Both groups of children in the present study performed better than those in Bialystok and Martin (2004), but the bigger difference was between the two groups of monolinguals. These results suggest that it could be important to attend to monolingual children’s performance, in addition to bilinguals’, when testing for a bilingual advantage. Our replication study is important because it helps with clarifying the validity of studies finding a bilingual advantage and to help future researchers know whether to build on their findings or not.

A hierarchical deficit model of reading disability: Evidence from dynamic causal modelling analysis

Deficits have been documented in visuo-orthographic processing as well as phonological retrieval/manipulation during visual word reading in individuals with reading disability (RD); however, the relationship between these deficits remains unclear. Previously, we found that during word reading, visuo-orthographic deficit appears to be a neural signature of RD, but deficits in phonological retrieval/manipulation appears to be a consequence of being RD (Cao et al., 2020). Therefore, in the current study, we directly tested the hypothesis that during visual word reading, deficit in phonological retrieval/manipulation may result from weakened input from visuo-orthographic regions, and that this relationship tends to be universal across languages. We conducted a dynamic causal modelling analysis of fMRI data from Chinese-English bilingual children (9–11 years, N = 78) with or without RD during a visual word rhyming judgment task. We found a weaker connection from the left inferior temporal gyrus (ITG) to the left dorsal inferior frontal gyrus (dIFG) in children with RD and reading controls than the connection found in age controls for both Chinese and English. This finding suggests that the phonological deficit at the dIFG may result from weak input from the visuo-orthographic region and this connection appears to be responsive to reading level rather than RD, because the reading-control children were similar to children with RD. We also found that the left ITG was selectively connected with language-specific regions (i.e., the left inferior parietal lobe (IPL) for Chinese and the left ventral inferior frontal gyrus (vIFG) for English) depending on the language being processed; however, this language selectivity was reduced in children with RD, suggesting that decreased language specialization is associated with RD. Using a double control design, our study suggests that during reading, the visuo-orthographic deficit of RD constrains the development of the connection from orthography to phonology and to other language-specific processing due to distorted quantity and quality of reading.

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.
