Effects of dual- and single-language exposure on children’s word learning: Experimentally testing the role of competition

This study investigated the role of dual- and single-language input in bilingual children’s word learning. In Experiment 1, 26 Spanish–English bilingual children aged 4 and 5 years (9 girls; 73% Latino; 65% White) learned novel words in single- and dual-language conditions. In the single-language condition, children learned English-like labels for novel objects. In the dual-language condition, the same children learned Spanish- and English-like labels for a different set of objects; all labels were produced by the same bilingual speaker, creating competition between the two languages. A second group of bilingual children (N = 25; 14 girls; 72% Latino; 40% White) participated in Experiment 2, which tested whether tagging language by speaker in the dual-language condition (mimicking the one person–one language input strategy) would influence performance. In both experiments, participants learned novel English words above chance (ps < .05) in both conditions, with better performance in the single-language condition. These results indicate an advantage for single-language learning contexts, but the theoretical roots and the practical value of this advantage are unclear.

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.

Dynamic assessment of narratives: Case studies of bilingual Filipino kindergarteners with language difficulties

The goal of the present study was to investigate the performance of four Filipino–English bilingual kindergarteners with language difficulties on a dynamic assessment of English narratives. Using a multiple case-study design, we examined the children's modifiability by detailing their responsiveness, level of skill transfer, and the amount and type of effort the examiner expended during two mediation sessions. We also assessed the children's narrative skills using the Test of Narrative Language—second edition (TNL-2). During mediation, similarities among the four children included difficulty answering wh-questions, little transfer of the newly learned skills, frequent focus on the story problem, and the need for continual prompting and repetition. However, the children showed individual learning styles, behavior when learning, and learning potential, prompting the examiner to apply different strategies to support their individual abilities. Gains on the TNL-2 were also negligible, consistent with the modifiability findings, apart from one child who showed improvement in comprehension scores. The case studies provide novel information regarding the narrative skills of Filipino bilingual children with language difficulties, an under-researched population. They can help guide expectations of such children during a dynamic assessment and suggest mediation strategies that clinicians could incorporate into their practice with other groups of bilingual children.

Relationships Among Motor, First, and Second Language Skills Among Bilingual Children With Language Disorders.

The purpose of this study was to determine the significance and directions of the relationships among oral and manual fine motor skills and language abilities among Spanish-English bilingual children. If such relationships exist, this would support a shared biological influence on motor and language development. Participants included 56 bilingual children, 24 of whom met criteria for developmental language disorder (DLD), recruited based on teacher concern for language and/or reading comprehension abilities. Students participated in a battery of baseline tests to determine motor, language, and cognitive abilities. Correlations among all variables were examined for direction of relationships. Regression models explored the predictive power of motor skills with Spanish and English language ability as the outcome measure. Oral fine motor abilities (diadochokinetic rate productions of /pa/ and /pata/) predicted Spanish (but not English) oral language abilities in the expected direction (i.e., faster rates were associated with better language). Manual fine motor performance on computer tapping tasks was not related to performance in either language. Oral fine motor abilities are related to language abilities in bilingual children, but only for the native language. We did not find reliable differences in oral and manual fine motor skills between groups of bilingual children with and without DLD. These findings support a limited role of shared biological influences on motor and language development.

The bilingual advantage: performing the non-word repetition test

The study investigated the accuracy of non-word production by bilingual and monolingual children. The participants (125 children in total) belonged to two groups of bilingual children with different language repertoires and one group of monolingual Lithuanians. The analysis revealed that the overall performance of both bilingual groups was better than in the monolingual group. The bilingual children demonstrated more accurate and statistically significant results in repeating longer and structurally more complex non-words. The findings of this study suggest that the bilinguals being acquainted with two phonological systems had a greater experience with diverse phonology, which ensured a more precise performance of the task.

Regular and Irregular Inflection in Different Groups of Bilingual Children and the Role of Verbal Short-Term and Verbal Working Memory

Bilingual children often experience difficulties with inflectional morphology. The aim of this longitudinal study was to investigate how regularity of inflection in combination with verbal short-term and working memory (VSTM, VWM) influences bilingual children’s performance. Data from 231 typically developing five- to eight-year-old children were analyzed: Dutch monolingual children (N = 45), Frisian-Dutch bilingual children (N = 106), Turkish-Dutch bilingual children (N = 31), Tarifit-Dutch bilingual children (N = 38) and Arabic-Dutch bilingual children (N = 11). Inflection was measured with an expressive morphology task. VSTM and VWM were measured with a Forward and Backward Digit Span task, respectively. The results showed that, overall, children performed more accurately at regular than irregular forms, with the smallest gap between regulars and irregulars for monolinguals. Furthermore, this gap was smaller for older children and children who scored better on a non-verbal intelligence measure. In bilingual children, higher accuracy at using (irregular) inflection was predicted by a smaller cross-linguistic distance, a larger amount of Dutch at home, and a higher level of parental education. Finally, children with better VSTM, but not VWM, were more accurate at using regular and irregular inflection.

Leisure reading in multilingual Singapore

What are bilingual children reading? Do children who enjoy reading books in one language also enjoy reading books in the other language? Drawing on survey data from 1,312 children (aged 9–11) in two government primary schools in Singapore, this study examined reading enjoyment, habits and preferences of two groups of bilingual children – English-Chinese and English-Malay bilingual children. Results showed that children generally enjoyed reading in English more than reading in Chinese/Malay, and that they read English books more often and for longer duration. Within each language, reading enjoyment was significantly associated with reading frequency and reading duration. Crosslinguistically, children’s reading duration and frequency in their two languages were closely related, despite their different reasons for reading English and Chinese/Malay books. Even though levels of reading enjoyment in the two languages were not significantly correlated, results suggested that English reading enjoyment may facilitate Chinese/Malay reading. Results highlight the important role of language policy, the focus of language curriculum and language-specific features in shaping bi-/multilingual children’s reading habits and preferences. Implications for classroom applications and the need to promote Chinese/Malay reading are discussed.

Articulation skills in bilingual children with a migration background: a comparison between bilingual Turkish-Dutch, Arabic-Dutch and monolingual Dutch children

Background/aimsThere is a lack of studies investigating articulation skills in bilingual children with a migration background. Therefore, the present study compared articulation skills in bilingual Turkish-Dutch/Moroccan Arabic-Dutch children with migration background and monolingual Dutch children without migration background. Moreover, possible factors influencing articulation skills were determined. Methods15 bilingual Turkish-Dutch, 15 bilingual Moroccan Arabic-Dutch and an age and gender matched group consisting of 15 monolingual Dutch children, all aged between 6 and 7 years and living in Flanders, were included in the present study. Articulation was evaluated using a picture naming test. Speech samples were transcribed phonetically and articulatory analysis, including a phonetic inventory and phonetic and phonological analyses, was performed. The phonetic analysis made a distinction between distortions, substitutions, additions, and omissions. For the phonological analysis, a distinction between syllable structure processes, substitution processes and assimilation processes was made. Moreover, parents were administered a self-report questionnaire to determine possible factors influencing articulation skills. ResultsA statistically significant difference in additions was found when comparing the three groups. Interestingly, both the Turkish-Dutch and Moroccan Arabic-Dutch groups used additions that were not present in the Dutch group (i.e. respectively addition of the [ə] and [ər]). Concerning phonological analysis, it was found that deletions of final consonants were more present in the bilingual groups compared to the monolingual group. Moreover, statistically significant effects of origin, home language, and language preference of the child were found on presence of both phonetic errors and phonological disorders. ConclusionFindings of the present study showed that some phonetic errors and phonological processes were more present in the group of bilingual children with migration background compared to the group of monolingual children without migration background. Interestingly, phonetic errors and phonological processes were more present when (1) the child had a Turkish origin, or (2) when the dominant language at the home environment was Turkish, or (3) when the preferred language of the child was Turkish. Given the increased attention to migration, findings of the present study are highly important for speech-language pathologists, teachers, and more generally, all professionals working with bilingual populations with a Moroccan Arabic or Turkish migration background.

Bilingualism in connection with executive functions and cognition in children in Slovenian bilingual area

The purpose of this study was to research the assumptions about the connection between bilingualism and results in the field of cognitive functioning. Research showing the advantage of bilingual individuals in comparison with monolinguals in cognitive functioning is often explained by the mechanisms that allow bilingual individuals to control and represent the two languages in the brain. Our study included children aged 9 to 11 years: a group of bilingual children who speak Slovene and Hungarian and a control group of monolingual, Slovene speaking children. We tested them with the following cognitive abilities tests: executive functions with TMT and Stroop test, working memory with digit span task forward and backward, verbal abilities with verbal fluency test and vocabulary. The data showed that, although verbal fluency was lower in bilingual group, bilingual children performed better on versions of Stroop task, which could indicate advantage in speed of processing and to lesser extent also in ability of handling conflicting information.

Production, comprehension and repetition of accusative case by monolingual Russian and bilingual Russian-Dutch and Russian-Hebrew-speaking children

AbstractThe present study explores the acquisition of the Russian accusative [acc] case inflections in two groups of bilingual children (Russian-Dutch and Russian-Hebrew) who acquire Russian as their Heritage Language (HL) and two groups of monolingual Russian-speaking children within theUnified Competition Model(MacWhinney, 2008,2012). Seventy-two typically developing children participated in the study. Children’s performance on three tasks was compared: elicited production, forced-choice comprehension and sentence repetition.The current study confirmed the predictions of theUnified Competition Model: monolingual children view the [acc] case inflection as a reliable cue. Conversely, bilingual children showed lower accuracy on nouns which require the use of a dedicated [acc] marker. Similarly, the percentage of children manifesting sensitivity to [acc] case cue was low in bilinguals. The findings of the study extend theUnified Competition Modelto patterns of HL acquisition in bilinguals. Cue detection in HL for bilinguals is challenged when exposure is limited.

A Cross-Cultural Comparison of Communicative Patterns in Bilingual and Monolingual Mother-Child Dyads in the United States and Thailand

Parental speech has some influences on children’s language development. The way parents speak with their children is often reflected in the children’s speech patterns. Prior research suggests that monolingual mother-child communication differs as a function of linguistic and cultural background. The present study examined communicative patterns of bilingual and monolingual mother-child dyads in Thailand and the United States to determine whether there are differences in conversational style and content between bilinguals and monolinguals who are native to different countries and cultures. Participants included four bilingual mother-preschooler dyads from Thailand, four bilingual mother-preschooler dyads from the US, and 21 English monolingual dyads from the US. Each dyad completed three tasks in English: prompted reminiscing, book reading, and toy play. Interactions were video-recorded, transcribed using Codes for the Analysis of Human Language (CHAT), and coded for language measures. Data analysis utilized maternal and child mean frequency of each language measure. Results revealed that English monolingual mothers provided more descriptions, posed more questions, used more emotion words, and discussed their thoughts and feelings more than both groups of bilingual mothers. Similarly, English monolingual children shared their thoughts and feelings more than the two groups of bilingual children in each task, whereas the bilingual groups did not differ in their use of other linguistic measures. We conclude that culture and language status can change how monolinguals and bilinguals communicate, even when speaking the same language.

The impact of older siblings on vocabulary learning in bilingual children

ABSTRACT This study examined the effects of older siblings’ L1/L2 use on the vocabulary and fast mapping skills in preschool-age children who learn Cantonese (L1) as a home language and start to learn English (L2) in preschool settings. Two groups of bilingual children participated in this study: (1) children whose older siblings used mostly L1 at home (‘Mostly L1’ group; n = 14) and (2) children whose older siblings used an equal amount of L1 and L2 at home (‘Equal L1/L2’ group; n = 13). Participants were tested using vocabulary measures and a fast mapping task. Results showed that there were no significant group differences in children’s vocabulary scores or in their fast mapping production scores in each language. However, when measured using a comprehension probe during the fast mapping task, the ‘Mostly L1’ group outperformed the ‘Equal L1/L2’ group in identifying the target novel words in L1, whereas there were no group differences in L2. The findings provide some preliminary evidence that older siblings who speak mostly L1 may contribute to their younger siblings’ L1 fast mapping skills.

Biliteracy and reading ability in children who learn Greek as a second language

ABSTRACT The differences and similarities in the word recognition and reading comprehension skills of monoliterate Albanian-Greek (ML2), biliterate Albanian-Greek (BL2) and monolingual (L1) children in grades 3–6 were examined in two cross-sectional studies. Participants completed standardized and experimental tasks measuring cognitive, oral language and reading skills. The first study explored the effect of biliteracy on Greek word recognition taking into account the impact of oral expressive vocabulary in that language. 24 BL2 and 66 ML2 were compared to 78 L1 speakers in visual word recognition. It was revealed that the two groups of bilingual children differed in word recognition. In addition, it demonstrated that oral proficiency in the second language can play a key role in second language word reading. Study 2 examined the differences in reading comprehension skills of 21ML2, 13BL2 and 19L1 children. ML2 children performed proficiently on text comprehension as their monolingual peers. However biliterate Albanian-Greek children had poorer performance than their L1 peers.

Cognitive Advantages of Bilingual Children in Different Sociolinguistic Contexts.

Many studies have shown that bilingual children outperform monolinguals on tasks testing executive functioning, but other studies have not revealed any effect of bilingualism. In this study we compared three groups of bilingual children in the Netherlands, aged 6–7 years, with a monolingual control group. We were specifically interested in testing whether the bilingual cognitive advantage is modulated by the sociolinguistic context of language use. All three bilingual groups were exposed to a minority language besides the nation’s dominant language (Dutch). Two bilingual groups were exposed to a regional language (Frisian, Limburgish), and a third bilingual group was exposed to a migrant language (Polish). All children participated in two working memory tasks (verbal, visuospatial) and two attention tasks (selective attention, interference suppression). Bilingual children outperformed monolinguals on selective attention. The cognitive effect of bilingualism was most clearly present in the Frisian-Dutch group and in a subgroup of migrant children who were relatively proficient in Polish. The effect was less robust in the Limburgish-Dutch sample. Investigation of the response patterns of the flanker test, testing interference suppression, suggested that bilingual children more often show an effect of response competition than the monolingual children, demonstrating that bilingual children attend to different aspects of the task than monolingual children. No bilingualism effects emerged for verbal and visuospatial working memory.

Predictors of reading and comprehension abilities in bilingual and monolingual children: a longitudinal study on a transparent language

Many studies have shown that learning to read in a second language (L2) is similar, in many ways, to learning to read in a first language (L1). Nevertheless, reading development also relies upon oral language proficiency and is greatly influenced by orthographic consistency. This longitudinal study aimed to analyze the role of linguistic predictors (phonological awareness, letter knowledge, pseudoword repetition, morphosyntactic comprehension, lexical knowledge and rapid naming) in reading outcomes (fluency, accuracy and comprehension) in a group of bilingual children (n = 30) reading Italian as an L2, compared to a group of monolingual children (n = 56). We ran a multi-group structural equation model. Our findings showed that rapid automatized naming was a significant predictor of reading speed in both groups. However, the study revealed different patterns of predictors for reading accuracy, predictors for monolinguals being LK, phonological awareness and lexical knowledge, while pseudoword repetition was a predictor for bilinguals. Morphosyntactic comprehension was the most significant predictor of comprehension skills in bilingual children. Implications for clinical and educational settings are discussed.

Cognitive profiles in bilingual children born to immigrant parents and Italian monolingual native children with specific learning disorders

PurposeThe aim of this study is to compare the Wechsler Intelligence Scale for Children® – fourth edition IV (WISC IV) intellectual profile of two groups of children with specific learning disorder, a group of bilingual children and a group of monolingual Italian children, in order to identify possible significant differences between them.Patients and methodsA group of 48 bilingual children and a group of 48 Italian monolingual children were included in this study. A preliminary comparison showed the homogeneity of the two groups regarding learning disorder typology and sociodemographic characteristics (age at WISC IV assessment, sex and years of education in Italy) with the exception of socioeconomic status. Socioeconomic status was then used as a covariate in the analysis.ResultsEven if the two groups were comparable in specific learning disorder severity and, in particular, in the text comprehension performance, our findings showed that the WISC IV performances of the bilingual group were significantly worse than the Italian group in Full Scale Intelligence Quotient (P=0.03), in General Ability Index (P=0.03), in Working Memory Index (P=0.009) and in some subtests and clusters requiring advanced linguistic abilities.ConclusionThese results support the hypothesis of a weakness in metalinguistic abilities in bilingual children with specific learning disorders than monolinguals. If confirmed, this result must be considered in the rehabilitation treatment.

Exploring the Differential Impact of Public Interventions on Indigenous People: Lessons from Mexico's Conditional Cash Transfer Program

This paper uses experimental panel data for Mexico from 1997 to 2000 in order to test assumptions on the impact of a conditional cash transfer (CCT) program on child labor and school attendance, adding to the literature by emphasizing the differential impact on indigenous households. Using data from the CCT program, PROGRESA (later on known as OPORTUNIDADES), we investigate the interaction between child labor, education and indigenous households. While indigenous children had a greater probability of working before the intervention, this probability is reversed after treatment in the program. Indigenous monolingual children also had lower school attainment compared with Spanish-speaking or indigenous bilingual children. After the program, school attainment among indigenous children increased, reducing the gap. In terms of child labor, the larger reduction is in the group of bilingual children.

Neural processing of speech in children is influenced by extent of bilingual experience

Language experience fine-tunes how the auditory system processes sound. Bilinguals, relative to monolinguals, have more robust evoked responses to speech that manifest as stronger neural encoding of the fundamental frequency (F0) and greater across-trial consistency. However, it is unknown whether such enhancements increase with increasing second language experience. We predict that F0 amplitude and neural consistency scale with dual-language experience during childhood, such that more years of bilingual experience leads to more robust F0 encoding and greater neural consistency. To test this hypothesis, we recorded auditory brainstem responses to the synthesized syllables ‘ba’ and ‘ga’ in two groups of bilingual children who were matched for age at test (8.4±0.67 years) but differed in their age of second language acquisition. One group learned English and Spanish simultaneously from birth (n=13), while the second group learned the two languages sequentially (n=15), spending on average their first four years as monolingual Spanish speakers. We find that simultaneous bilinguals have a larger F0 response to ‘ba’ and ‘ga’ and a more consistent response to ‘ba’ compared to sequential bilinguals and we demonstrate that these neural enhancements track with years of bilingual experience. These findings support the notion that bilingualism enhances subcortical auditory processing.

The English phonological awareness skills of 5;0–6;0-year-old Polish–English, Portuguese–English bilingual speakers and English monolingual children

Previous research on bilingual children's phonological awareness (PA) abilities is contradictory. Some studies suggest that bilinguals are advantaged compared to monolinguals, benefiting literacy acquisition. Other research indicates that any advantage in PA skills is transient, influenced by language learning context, proficiency in both languages, and the language pair being acquired. This study compared the English PA skills of two groups of bilingual children and a monolingual English-speaking group matched for age, gender, and social class. The 54 participants were 5 to 6 years old, in their first or second year of school. There were 18 children speaking Polish–English, 18 children speaking Portuguese–English and 18 English-speaking monolingual children. Their letter knowledge, syllable, onset–rime, and phoneme awareness were assessed using subtests from standardized assessments plus one task specifically designed for this study. Parents of bilingual children completed a questionnaire about their child's language background and language use. The three groups did not differ on tasks assessing syllable awareness, identification of word initial sounds or letter knowledge. The results of tasks assessing alliteration, rhyme, and phoneme awareness indicated that typically developing English-speaking monolingual children performed better than matched typically developing bilingual children. The monolinguals and the Polish-English bilinguals performed equally well on the rhyme detection task. The language use questionnaire responses provided insight into factors affecting the results. It was concluded that no bilingual advantage for PA was apparent in the bilingual populations studied. These results suggest that bilingual children are likely to initially find English literacy difficult.

The acquisition of copula verbs in Basque by bilinguals

This article focuses on the acquisition of copula verbs in Basque by Basque–Spanish bilinguals. Basque and Spanish have two copula verbs: izan and egon and ser and estar, respectively. Basque copulas are similar to their Spanish counterparts in terms of the grammatical contexts in which they are used. However, Basque and Spanish differ in one specific property, the progressive, which is built with izan in Basque. This article assumes the theoretical framework of Zagona for Basque because copula selection can be accounted for by this approach. The present study is the first one to address the issue of the acquisition of copula verbs by Basque–Spanish bilingual children in Basque; we analyze the language used in a storytelling task by 19 Basque-dominant bilinguals compared to that used by 19 child L2 Basque learners, in order to elucidate whether both groups of bilingual children use the copula in a target-like way in Basque. The study shows that no copula choice errors are produced by any of the participants with any predicates. The distribution of the predicates very much resembles the distribution of the predicates in previous studies for Spanish. Adhering to Zagona’s framework, the progressive was included in our study. In this respect, the progressive is used in a target-deviant manner, a finding that can be attributed to crosslinguistic influence. These results are ultimately attributed to children’s parallel knowledge of both interpretable and uninterpretable features, although uninterpretable features seem to be acquired a little earlier.
