This study investigates the cross-linguistic priming effect in the syntactic written output of late bilingual Levantine Arabic speakers who learn English as a second language. In particular, we examined priming sentence type (simple vs. complex sentences) and priming language condition (Levantine Arabic vs. English). Forty-nine bilinguals (Mean age = 33.3, SD = 8.5), who learned Levantine Arabic as their L1 and English as their L2, were primed with a short paragraph presented on the computer screen in either English or Levantine Arabic and asked to produce a written response in the counterpart language. Logistic regression analysis revealed a significant cross-linguistic priming effect, suggesting that the syntactic structure of the prime in the participants’ first language (Levantine Arabic) predicts the participants’ written output in the second language (English), and the reverse is also true. However, there was no significant effect of priming sentence type (simple vs. complex) on the likelihood of producing primed res ponses, indicating that both priming conditions yielded similar levels of priming. In contrast, there was a significant effect of the priming language condition, with participants significantly more likely to produce syntactically primed responses when the priming language was Arabic compared to English. In addition, there was a significant interaction between the priming language condition and priming sentence type: Arabic priming led to more simple sentence production in English, whereas English priming did not significantly affect sentence complexity in Arabic. These findings align with the shared syntax account but highlight the need to consider factors such as language dominance in bilingual syntactic processing.

Purpose: The purpose of this study was to compare the novel word learning skills between Cantonese–English bilingual children at risk for developmental language disorder (DLD) and their typically developing (TD) peers. Method: Participants were 24 Cantonese–English bilingual preschool children at risk for DLD and 38 TD children. Each participant was presented with eight novel words in Cantonese (first language [L1]) and eight in English (second language [L2]) over eight weekly sessions. Children's existing lexical knowledge was measured using the moving-average number of different words in language samples in L1 and L2. Results: Bilingual children at risk for DLD were scored lower than their TD peers for both languages over time. The role of lexical knowledge in children's word learning differed between the TD and DLD groups: Lexical knowledge in L1 was a predictor of L1 word learning in TD children, while lexical knowledge in L2 predicted L2 word learning in children at risk for DLD. In addition, significant cross-linguistic effects were found from L2 to L1 for both groups. Conclusions: This study underscores the complexity of novel word learning in bilingual children at risk for DLD. Clinically, these findings suggest the value of tracking learning trajectories in bilingual children across both languages.

This study explored the feasibility of implementing an individualised vocabulary intervention for dual language learners through teachers, who leverage their knowledge about their students to address each child's diverse needs. Participants were 32 Cantonese-English pre-school dual language learners and 16 teacher implementers from eight classrooms of a Head Start Programme. During the 3-week programme, teacher implementers were given an individualised set of 12 target words for each student. Implementation was measured using daily logs, questionnaires, and interviews. Children's immediate word learning was reported by teachers and word retention was measured two weeks after the intervention. Teacher implementers were able to teach the individual target words to each participant in one-on-one interactive sessions 94% of the time. Various teaching strategies were used along with culturally relevant teaching materials. On average, children learned 92% of the target words and retained 42% of the target words. The study highlights the practicability of implementing an individualised intervention programme by harnessing teachers' knowledge of the children they work with. The results have implications for building a high-quality and culturally-responsive intervention programme for dual language learners.

This scoping review aimed to investigate the communication strategies utilized by children who acquire a minority language (L1) and subsequently learn a community language (L2) during what is commonly referred to as the “silent period.” Electronic database searches were conducted using keywords such as “silent period” and “bilingual children,” resulting in the inclusion of 40 studies in the review. The findings revealed that emergent bilingual children utilize various communication strategies, including nonverbal communication, private speech, and their L1, to communicate within classroom environments. The findings shed light on the adaptability of emergent bilingual children during early stage of L2 acquisition. Furthermore, our review provides information about the classroom contexts such as teacher support and peer interactions where children develop their L2 skills. From a clinical perspective, recognizing these strategies and classroom contexts could significantly enhance the screening process for emergent bilingual children.

This study investigates the semantic development of heritage bilingual preschool children aged 3 to 5 who acquire Cantonese as their heritage language (HL) at home and English as their community language (L2) in school settings. The research examines how bilingual children organize and access their vocabulary in two distinct languages and how their heritage language influences semantic development in L2. We examined their performance in Word Association Identification Task (WAID) and Word Association Task (WAT) in both languages. Results showed that they perform similarly in WAID in both languages, with higher accuracy in semantically unrelated conditions. The WAT results showed that children had more syntagmatic responses in Cantonese than in English, but had similar paradigmatic responses in both languages. Regression analysis revealed that paradigmatic responses in Cantonese predicted children's English paradigmatic responses. Their English paradigmatic responses were also associated with WAID performance in English. This study contributes to understanding heritage bilingual children's semantic development, with implications for education and language support.

This study investigates the impact of a theatre-based vocal empowerment program on the vocal and language characteristics and the self-perceptions of young bilingual Egyptian women. The program used applied theatre, a dramatic practice that promotes civic action by utilizing improvisational techniques to engage participants in exploring solutions to self-identified community concerns. These techniques supported participants’ pursuit of vocal empowerment: the ability to comfortably express their intended content with a clear audible voice, accompanied by the belief that what they had to say was worthwhile. The program was implemented in Alexandria and Aswan, two Egyptian cities in different regions of the country, with distinct socio-economic profiles. Thirty-six young women from Aswan and nineteen from Alexandria participated. The program was facilitated in Arabic, for 90 minutes per day over twelve consecutive days in 2018. Participants in both groups spoke Arabic as a home language and studied English in school settings but differed in their educational experiences and English proficiency. The vocal and language characteristics of each participant were tested in Arabic and English pre- and post- program using a spontaneous speech task and a reading aloud task. Their self-perceptions were evaluated through a vocal self-perception survey. Results indicated that participants responded differently in each city. In Alexandria, participants showed significant improvement in language skills (e.g., mean length of utterance). In contrast, participants in Aswan showed a significant change in fundamental frequency. Overall, the self-surveys indicated that all participants experienced an increased sense of confidence, a stronger belief in self-authorship, and an increased desire to voice their opinions clearly in public; however, there were subtle differences between the groups. In analyzing these results, we conclude that to design effective vocal empowerment outreach programs internationally, it is necessary to consider participants’ cultural backgrounds, language diversity, and socio-economic status.

Purpose: This study addresses the question of whether sequential bilingual children’s past tense marking development in their second language (L2) is affected by their knowledge of temporal marking in their first language (L1). We investigated whether Cantonese-English sequential bilingual children’s knowledge of aspect markers in Cantonese (L1), along with external and internal factors, predicts their past tense marking in English (L2). Method: We examined 39 pre-school children’s production of perfective aspect markers in Cantonese and regular and irregular past tense morphemes in English using a story-retell task administered in both languages. Result: The results showed that children produced significantly more irregular past tense verbs than regular past tense verbs in English. Their English irregular past tense use, but not regular past tense use, was predicted by their knowledge of aspect markers in Cantonese. Conclusion: Findings suggest that semantic transfer between Cantonese and English might contribute to the early stages of acquiring English past tense marking. Clinically, the results could potentially lead to more informed assessment procedures and better diagnostic decision making for bilingual children.

The purpose of this study was to examine Cantonese-speaking Chinese American immigrant parents' socialization of emotions in bilingual bicultural preschool children, using a combination of a parent questionnaire and parent language samples from emotion-elicited storytelling tasks. Sixteen Cantonese-speaking parents and their children participated in this study. Children were sequential bilinguals who were exposed to Cantonese (L1) at home since birth, and then learned English (L2) at school. The Chinese parent questionnaire examined parents' emotion talk in the home, as well as the child's dual language background and language distribution. Parents' language samples in Cantonese were collected from three parent-child storytelling tasks that each elicited a different type of negative emotion (sad, angry, scared). Results from the parent questionnaire and the parent language samples were analyzed using quantitative and qualitative methods. In the parent questionnaire, correlation analysis revealed that parents' use of guilt emotions was not associated with any of the other emotion words, suggesting that parents may not talk about guilt as frequently as the other emotions. Results from the parents' language samples showed no significant differences between parents' number of emotion words and emotion explanations across the storytelling tasks, suggesting that parents used negative emotion words similarly across all three books. Further qualitative analysis between the parent questionnaire and the language samples revealed patterns in the way parents use Chinese emotion words with their children. Findings illustrate how the combined use of a parent questionnaire and parent language samples offer complementary information to provide a more comprehensive understanding about Chinese American immigrant parents' socialization of emotions.

The purpose of the study was to examine whether monolingual adults can identify the bilingual children with LI on the basis of children’s response speed to the examiner. Participants were 37 monolingual English-speaking young adults. Stimuli were 48 audio clips from six sequential bilingual children (48 months) who were predominately exposed to Cantonese (L1) at home from birth and started to learn English (L2) in preschool settings. The audio clips for each child were selected from an interactive story-retell task in both Cantonese and English. Three of the children were typically developing, and three were identified as having a language impairment. The monolingual adult participants were asked to judge children’s response times for each clip. Interrater reliability was high (Kalpha = 0.82 for L1; Kalpha = 0.75 for L2). Logistic regression and receiver operating characteristic curves were used to examine the diagnostic accuracy of the task. Results showed that monolingual participants were able to identify bilingual children with LI based on children’s response speed. Sensitivity and specificity were higher in Cantonese conditions compared to English conditions. The results added to the literature that children’s response speed can potentially be used, along with other measures, to identify bilingual children who are at risk for language impairment.

Purpose: This research project examined the vocabulary growth patterns of typically developing (TD) Cantonese–English dual language learners (DLLs) and their peers who are at risk for language impairment. Method: Two studies were done. Study 1 examined the concurrent validity of a pilot vocabulary screening measure, the Kai Ming Vocabulary Test, that was designed for Cantonese–English preschool DLLs. Participants were 53 preschool children who learned Cantonese as their first language (L1) and English as a second language (L2). Their scores on the Kai Ming Vocabulary Test were examined in relation to their language sample measures, including number of different words and mean length of utterance, in L1 and in L2. Study 2 examined the vocabulary growth patterns of 24 TD Cantonese–English DLL preschoolers and 24 DLLs who are at risk for language impairment (At-Risk group). Each child was tested 3 times during an academic year. Results: Results of Study 1 showed that children's vocabulary scores ( n = 53) were significantly correlated with their language sample measures in each language. In Study 2, hierarchical linear models were used to compare the TD and At-Risk groups. Results showed that children in the At-Risk group had lower L1 receptive vocabulary scores and children in the TD group had relatively higher L2 expressive vocabulary gains. Conclusions: Children who are at risk are likely to continue to have lower vocabulary knowledge compared to their TD peers. The growth trajectories of DLLs provide valuable information for early identification and intervention.
