The impact of early auditory experience for the acquisition of morphosyntactic abilities and working memory.

Difficulty in acquiring object clitics (OCs), and the omission of OCs more specifically, is used as a marker of developmental language disorder (DLD) in children learning French. Research also suggests that OCs are a complex morphosyntactic property of French and, as such, they could be particularly taxing for working memory (WM) resources. In light of previous research, it seems more likely that difficulties with OCs could be a marker for atypical early language acquisition.

The development of phonological memory and language: A multiple groups approach.

Pierce et al. (2017) have proposed that variations in the timing, quality and quantity of language input during the earliest stages of development are related to variations in the development of phonological working memory and, in turn, to later language learning outcomes. To examine this hypothesis, three groups of children who are at-risk for language learning were examined: children with cochlear implants (CI), children with developmental language disorder (DLD), and internationally-adopted (IA) children, Comparison groups of typically-developing monolingual (MON) children and second language (L2) learners were also included.

Professional practices and opinions about services available to bilingual children with developmental disabilities: An international study.

This study aimed to gather information from school- and clinic-based professionals about their practices and opinions pertaining to the provision of bilingual supports to students with developmental disabilities. Using an online survey, data were collected in six socio-culturally and linguistically diverse locations across four countries: the United States, Canada, the United Kingdom, and the Netherlands. In total, 361 surveys were included in the analysis from respondents who were primarily teachers and speech-language pathologists working in schools, daycares/preschools, or community-based clinics.

Bilingualism in children with developmental disorders: A narrative review.

Children with developmental disabilities (DD) often need and sometimes opt to become bilingual. The context for bilingual acquisition varies considerably and can impact outcomes. In this first article of the special issue, we review research on the timing and amount of bilingual exposure and outcomes of either direct language intervention or educational placements in three groups of children with DD: Specific Language Impairment (SLI), Autism Spectrum Disorders (ASD), and Down syndrome (DS).

Predicting writing development in dual language instructional contexts: exploring cross-linguistic relationships.

This study examined whether decoding and linguistic comprehension abilities, broadly defined by the Simple View of Reading, in grade 1 each uniquely predicted the grade 6 writing performance of English-speaking children (n = 76) who were educated bilingually in both English their first language and French, a second language. Prediction was made from (1) English to English; (2) French to French; and (3) English to French. Results showed that both decoding and linguistic comprehension scores predicted writing accuracy but rarely predicted persuasive writing.

Past experience shapes ongoing neural patterns for language.

Early experiences may establish a foundation for later learning, however, influences of early language experience on later neural processing are unknown. We investigated whether maintenance of neural templates from early language experience influences subsequent language processing. Using fMRI, we scanned the following three groups performing a French phonological working memory (PWM) task: (1) monolingual French children; (2) children adopted from China before age 3 who discontinued Chinese and spoke only French; (3) Chinese-speaking children who learned French as a second language but maintained Chinese.

Mapping the unconscious maintenance of a lost first language.

Optimal periods during early development facilitate the formation of perceptual representations, laying the framework for future learning. A crucial question is whether such early representations are maintained in the brain over time without continued input. Using functional MRI, we show that internationally adopted (IA) children from China, exposed exclusively to French since adoption (mean age of adoption, 12.

The acquisition of accusative object clitics by IA children from China: evidence of early age effects?

The present study compared the performance of twenty-seven French-speaking internationally adopted (IA) children from China to that of twenty-seven monolingual non-adopted French-speaking children (CTL) matched for age, gender, and socioeconomic status on a Clitic Elicitation task. The IA children omitted significantly more accusative object clitics and made significantly more agreement errors using clitics than the CTL children. No other significant differences were found between the groups.

Language and memory abilities of internationally adopted children from China: evidence for early age effects.

The goal of the present study was to examine if internationally adopted (IA) children from China (M = 10;8) adopted by French-speaking families exhibit lags in verbal memory in addition to lags in verbal abilities documented in previous studies (Gauthier & Genesee, 2011). Tests assessing verbal and non-verbal memory, language, non-verbal cognitive ability, and socio-emotional development were administered to thirty adoptees. Their results were compared to those of thirty non-adopted monolingual French-speaking children matched on age, gender, and socioeconomic status.

Brain responses before and after intensive second language learning: proficiency based changes and first language background effects in adult learners.

This longitudinal study tracked the neuro-cognitive changes associated with second language (L2) grammar learning in adults in order to investigate how L2 processing is shaped by a learner's first language (L1) background and L2 proficiency. Previous studies using event-related potentials (ERPs) have argued that late L2 learners cannot elicit a P600 in response to L2 grammatical structures that do not exist in the L1 or that are different in the L1 and L2. We tested whether the neuro-cognitive processes underlying this component become available after intensive L2 instruction.

Acquisition of English grammatical morphology by internationally adopted children from China.

Acquisition of English grammatical morphology was examined in five internationally adopted (IA) children from China (aged 0;10-1;1 at adoption) during the first three years' exposure to English to determine whether acquisition patterns were characteristic of child second language (L2) learners or monolingual first language (L1) learners. Results from spontaneous and elicited speech showed that IA children acquired grammatical morphemes similarly to L1 learners; namely, (1) non-tense-marking morphemes were acquired earlier than tense-marking morphemes; (2) BE was acquired in synchrony with other tense-marking morphemes; and (3) a high percentage of omission errors and a low percentage of commission errors were observed.

Language development in internationally adopted children: a special case of early second language learning.

The French language development of children adopted (n=24) from China was compared with that of control children matched for socioeconomic status, sex, and age. The children were assessed at 50 months of age, on average, and 16 months later. The initial assessment revealed that the 2 groups did not differ with respect to socioemotional adjustment or intellectual abilities.

Bilingual children's acquisition of the past tense: a usage-based approach.

Bilingual and monolingual children's (mean age=4;10) elicited production of the past tense in both English and French was examined in order to test predictions from Usage-Based theory regarding the sensitivity of children's acquisition rates to input factors such as variation in exposure time and the type/token frequency of morphosyntactic structures. Both bilingual and monolingual children were less accurate with irregular than regular past tense forms in both languages. Bilingual children, as a group, were less accurate than monolinguals with the English regular and irregular past tense, and with the French irregular past tense, but not with the French regular past tense.

Bilingual children's repairs of breakdowns in communication.

This study examined two- (n = 10) and three-year-old (n = 16) French-English bilingual children's repairs of breakdowns in communication that occurred when they did not use the same language as their interlocutor (Language breakdowns) and for other reasons (e.g. inaudible utterance).

Crosslinguistic influence in bilingual acquisition: subject omission in learners of Inuktitut and English.

This study investigates subject omission in six English-Inuktitut simultaneous bilingual children, aged 1;8-3;9, to examine whether there are cross-language influences in their language development. Previous research with other language pairs has shown that the morphosyntax of one language can influence the development of morphosyntax in the other language. Most of this research has focused on Romance-Germanic language combinations using case studies.

Language-experience facilitates discrimination of /d-th/ in monolingual and bilingual acquisition of English.

To trace how age and language experience shape the discrimination of native and non-native phonetic contrasts, we compared 4-year-olds learning either English or French or both and simultaneous bilingual adults on their ability to discriminate the English /d-th/ contrast. Findings show that the ability to discriminate the native English contrast improved with age. However, in the absence of experience with this contrast, discrimination of French children and adults remained unchanged during development.

French-English bilingual children with SLI: how do they compare with their monolingual peers?

The goal of this study was to determine whether bilingual children with specific language impairment (SLI) are similar to monolingual age mates with SLI, in each language. Eight French-English bilingual children with SLI were compared to age-matched monolingual children with SLI, both English and French speaking, with respect to their use of morphosyntax in language production. Specifically, using the extended optional infinitive (EOI) framework, the authors examined the children's use of tense-bearing and non-tense-bearing morphemes in obligatory context in spontaneous speech.
