Little is known about the productive morphosyntax of Norwegian children with developmental language disorder (DLD). The current study examined morphosyntax in Norwegian-speaking children with DLD (n =19) and a control group that was pairwise matched for age, gender, and intelligence quotient (IQ; n = 19). The children’s sentence repetitions were studied through the lens of Processability Theory. The group differences were largest for grammatical structures at the latest developmental stage of the processability hierarchy. The Norwegian subordinate clause word order, belonging to the latest stage of the processability hierarchy, stood out as particularly challenging for children with DLD. Only 2 children with DLD but 16 children in the control group produced a subordinate clause with subordinate clause word order. Categorization of children’s errors revealed that children with DLD made more errors of all types (addition, omission, substitution, inflection and word order) but especially errors of omission and inflection.

Children who are refugees become bilingual in circumstances that are often challenging and that can vary across national contexts. We investigated the second language (L2) syntactic skills of Syrian children aged 6-12 living in Canada (n = 56) and the Netherlands (n = 47). Our goal was to establish the impact of the first language (L1 = Syrian Arabic) skills on L2 (English, Dutch) outcomes and whether L1–L2 interdependence is influenced by the length of L2 exposure. To measure L1 and L2 syntactic skills, cross-linguistic Litmus Sentence Repetition Tasks (Litmus-SRTs) were used. Results showed evidence of L1–L2 interdependence, but interdependence may only surface after sufficient L2 exposure. Maternal education level and refugee camp experiences differed between the two samples. Both variables impacted L2 outcomes in the Canadian but not in the Dutch sample, demonstrating the importance to examine refugee children’s bilingual language development in different national contexts.

Sentence repetition tasks have been widely used in the last years as a diagnostic tool in developmental language disorders. However in Spanish there are few (if any) of these instruments, especially for younger children. In this context, we develop a new Sentence Repetition Task for assessing language (morphosyntactic) abilities of very young Spanish children. A list of 33 sentences of different length and complexity was created and included in the task. A total of 130 typical developing children from 2 to 4 years of age were engaged in a play situation and asked to repeat the sentences. Children’s answers were scored for accuracy at sentence and word level and error analysis at the word level was undertaken. Besides a subsample of 92 children completed a non-word repetition task. First results show its adequacy to children from 2 to 4 years of age, its capacity to discriminate between different developmental levels, and its concurrent validity with the nonword repetition task.

Though previous research has shown that sentence repetition (SR) is an informative tool for identifying developmental language disorder (DLD) in bilinguals, little is understood about the skills that underlie children's performance on the task. With a population of 136 school-age Spanish–English bilinguals, the present study explores the contribution of verbal short-term memory, vocabulary, and language exposure on two SR tasks developed in English and Spanish. Results indicate that these skills may differentially underlie SR in typical versus disordered populations. Whereas the strongest predictors of English SR performance for typical bilingual children were expressive vocabulary and language exposure, bilingual children with DLD relied most heavily on verbal short-term memory. ROC curves to determine the classification accuracy of SR were conducted. Classification accuracy was excellent, with area under the curve reaching .92 for the English SR task and .87 for Spanish SR.

Theories of language processing differ with respect to the role of abstract syntax and semantics vs surface-level lexical co-occurrence (n-gram) frequency. The contribution of each of these factors has been demonstrated in previous studies of children and adults, but none have investigated them jointly. This study evaluated the role of all three factors in a sentence repetition task performed by children aged 4–7 and 11–12 years. It was found that semantic plausibility benefitted performance in both age groups; syntactic complexity disadvantaged the younger group but benefitted the older group; while contrary to previous findings, n-gram frequency did not facilitate, and in a post-hoc analysis even hampered, performance. This new evidence suggests that n-gram frequency effects might be restricted to the highly constrained and frequent n-grams used in previous investigations, and that semantics and morphosyntax play a more powerful role than n-gram frequency, supporting the role of abstract linguistic knowledge in children's sentence processing.

Recent research has focused on bilingual children’s performance on non-word repetition (NWR) and sentence repetition (SR) tasks, but it remains unclear how their scores can be expected to vary as a function of language exposure, which creates challenges for developing age-appropriate performance expectations. With the goal of examining the impact of limited language exposure on these tasks, French NWR and SR performance from 33 first graders (mean age 6 years, 10 months) in early total French immersion in English-speaking Canada was compared to prior work on bilinguals acquiring French in France. With a mean length of exposure of 1 year, 7 months, but a mean cumulative length of exposure of only 3 months, the children in immersion have much less daily exposure to French than the bilinguals in France. The results showed that children in immersion patterned with the other bilinguals for NWR, but had much weaker SR performance. Within-subjects analyses revealed that, for SR, the children in immersion had stronger scores on wh-questions and relative clauses, which suggests that these structures may be less sensitive to language exposure.

We examine the role of language production mechanisms in sentence repetition, a task widely used as a diagnostic tool in developmental disorders. We investigate sentence repetition in 5- to 8-year-old native speakers of Kannada, an inflectionally rich language of India. The inflectional characteristics of the language make it an ideal testing ground for exploring the engagement of grammatical and phonological encoding processes. We presented active, passive, and embedded sentences and, in a subset of the material, we also manipulated sentence length. Using accuracy and speech error analyses at the sentence, word, and affix levels, we provide evidence that individual differences in task performance are influenced by the linguistic properties of the material. These findings clarify the role of key language production mechanisms involved in sentence repetition. We propose that it is the versatility to develop a profile across several language production mechanisms that makes sentence repetition particularly useful as a clinical tool.

In this study 160 children, aged 11 years with a definite history of specific language impairment (SLI), completed four tasks that could be potential positive psycholinguistic markers for this impairment: a third person singular task, a past tense task, a nonword repetition task, and a sentence repetition task. This allowed examination of more than one type of marker simultaneously, facilitating both comparisons between markers and also evaluation of combinations of markers in relation to identifying SLI. The study also provided data regarding the markers in relation to nonverbal IQ, made use of new normative data on all tasks, and examined marker accuracy in relation to current language status. The results show that markers vary in accuracy, with sentence repetition (a previously unused marker) proving to be the most useful. This psycholinguistic marker shows high levels of sensitivity (90%), specificity (85%), and overall accuracy (88%), as well as being able to identify the majority of children whose current language status falls in the normal range despite a history of SLI.
