Purpose Developmental language disorder (DLD) is a developmental disorder where children fail to acquire language in the absence of a clear cause. Many studies have reported general motor deficits in children with DLD, but no studies have uncovered a cure. The purpose of our study is to better understand the underlying motor deficits in DLD, starting from uninhibited primary reflexes—which are the most basic stage of motor development. Knowledge of this motor–language relationship should lead to earlier and more targeted interventions in young children with DLD. Method Children with DLD ( n = 75, age range: 4–10 years) and 99 age-matched typically developing (TD) children completed a nonword repetition test to assess DLD and six other tests to assess primitive reflexes. Results Children with DLD demonstrated higher levels of persistent primitive reflexes compared to TD children. As the scores for neuromotor immaturity increased, nonword repetition test scores decreased ( r = −.44, p < .01). Results indicated that TD children exhibited lower neuromotor immaturity ( M = 7.63, SD = 3.75) compared to children with DLD ( M = 13.51, SD = 4.47). All primitive reflexes (the Moro reflex, the symmetrical tonic neck reflex in flexion and in extension, the asymmetrical tonic neck reflex, the tonic labyrinthine reflex, and the Galant reflex) turned out to be statistically significantly different for the TD and DLD groups ( p < .001). We also observed some differences between sexes. Conclusions Children with impaired language development underwent slower neuromotor development. However, further research is needed to determine whether motor intervention programs that inhibit primitive reflexes are helpful for children with DLD.

Purpose This study examined the performance of Gulf Arabic–speaking children with developmental language disorder (DLD) on a Gulf Arabic nonword repetition (GA-NWR) test and compared it to their age- and language-matched groups. We also investigated the role of syllable length, wordlikeness, and phonological complexity in light of NWR theories. Method A new GA-NWR test was conducted with three groups of Gulf Arabic–speaking children: school-age children with DLD, language-matched controls (LCs), and age-matched controls (ACs). The test consisted of two- and three-syllable words that either had no clusters, medial clusters, final clusters, or medial + final clusters. Results The GA-NWR distinguished between the performance of children with DLD and the LC and AC groups. Results showed significant syllable length, wordlikeness, and phonological complexity effects. Differences between the DLD and typically developing groups were seen in two- and three-syllable nonwords; however, when compared on nonwords with no clusters, children with DLD were not significantly different from the LC group. Conclusions The GA-NWR test differentiated between children with DLD and their ACs and LCs. Findings, therefore, support its clinical utility in this variety of Arabic. Results showed that phonological processing factors, such as phonological complexity, may have stronger effects when compared to syllable length effects.

Repetition Task

Purpose Studies have shown that children with typical development (TD) respond to frequency and predictability when repeating nonidiomatic multiword sequences (e.g., go wash your hands ). We extended these findings by explicitly examining the interaction between frequency and predictability in a repetition task for children with developmental language disorder (DLD) and children with TD. Method We created 48 four-word phrases, manipulating two factors: the frequency of occurrence of the entire four-word phrase (e.g., look in the mirror vs. look in the basket ) and the predictability of the fourth word in the phrase given the preceding three words (e.g., corn on the ___ vs. look in the ___ ). These phrases were presented in a repetition task to 17 children with DLD ( M age = 58.89 months), 19 same-age children with TD ( M age = 59.79 months), and 17 younger children with TD matched to the DLD group on nonword repetition and mean length of utterance ( M age = 38.94 months). Children's repetitions were judged for the presence or absence of word and morphological errors. Only the first three words of the sequence were scored (e.g., look in the ). Results We found a main effect of sequence frequency, with high-frequency sequences being repeated more accurately than low-frequency sequences, modulated by a significant interaction with predictability, where the effect of sequence frequency was larger for sequences with high-predictability contexts than for sequences with low-predictability contexts. We also found a significant effect of group, with children with DLD demonstrating poorer overall performance, particularly when compared to the same-age group with TD. Conclusions Frequency and predictability are strong predictors of language production in children with TD. These factors also have effects for children with DLD, raising important clinical questions about the design of facilitative contexts for the teaching of difficult linguistic forms.

Purpose The aim of the current study was to investigate whether dual language experience modulates the efficiency of the 3 attentional networks (alerting, orienting, and executive control) in typically developing (TD) children and in children with developmental language disorder (DLD). Method We examined the attentional networks in monolingual and bilingual school-aged children (ages 8–12 years) with and without DLD. TD children (35 monolinguals, 23 bilinguals) and children with DLD (17 monolinguals, 9 bilinguals) completed the Attention Network Test ( Fan et al., 2002 ; Fan, McCandliss, Fossella, Flombaum, & Posner, 2005 ). Results Children with DLD exhibited poorer executive control than TD children, but executive control was not modified by bilingual experience. The bilingual group with DLD and both TD groups exhibited an orienting effect, but the monolingual group with DLD did not. No group differences were found for alerting. Conclusions Children with DLD have weak executive control skills. These skills are minimally influenced by dual language experience, at least in this age range. A potential bilingual advantage in orienting may be present in the DLD group.

Children with hearing impairment (HI) are at an increased risk of developing speech and language problems similar to those of children with developmental language disorder (DLD), including difficulties with phonology and grammar. This study investigated similarities and differences in phonological and grammatical production between children with bilateral sensorineural HI ( n = 14) and children with DLD ( n = 30) between 4-6 years of age and age-matched controls with typical language development and normal hearing (TLD) ( n = 29), all with Swedish as their first language. Production of consonants, vowels, stress patterns and tonal word accents was assessed in a picture naming task, and in a word and nonword repetition task. Grammatical production was assessed for verb and noun morphology, and syntax. While performance for both children with HI and DLD were generally significantly below that of the controls with TLD, production of accents and syntax emerged as relative strengths. There were few differences between the between the children with HI and DLD, but noun–adjective agreement in predicative was more challenging for the children with HI. The results have implications for language assessment and planning of intervention.

Sentence Repetition

Purpose Sentence repetition and nonword repetition assess different aspects of the linguistic system, but both have been proposed as potential tools to identify children with developmental language disorder (DLD). Cross-linguistic investigation of diagnostic tools for DLD contributes to an understanding of the core features of the disorder. This study evaluated the effectiveness of these tools for the Vietnamese language. Method A total of 104 kindergartners (aged 5;2–6;2 [years;months]) living in Vietnam participated, of which 94 were classified as typically developing and 10 with DLD. Vietnamese sentence repetition and nonword repetition tasks were administered and scored using multiple scoring systems. Sensitivity, specificity, and likelihood ratios were calculated to assess the ability of these tasks to identify DLD. Results All scoring systems on both tasks achieved adequate to excellent sensitivity or specificity, but not both. Binary scoring of sentence repetition achieved a perfect negative likelihood ratio, and binary scoring of nonword repetition approached a highly informative positive likelihood ratio. More detailed scoring systems for both tasks achieved moderately informative values for both negative and positive likelihood ratios. Conclusions Both sentence repetition and nonword repetition are valuable tools for identifying DLD in monolingual speakers of Vietnamese. Scoring systems that consider number of errors and are relatively simple (i.e., error scoring of sentence repetition and syllables scoring of nonword repetition) may be the most efficient and effective for identifying DLD. Further work to develop and refine these tasks can contribute to cross-linguistic knowledge of DLD as well as to clinical practice.

This paper presents the Croatian version of the Multilingual Assessment tool for Narratives (MAIN), outlines its development and describes the research that has used it to assess narrative skills in monolingual and bilingual speakers. The Croatian version of MAIN has so far been used in three research projects and results have been presented in five peer-reviewed articles (published or in press) covering a total of 175 children in the age range from 5;0 to 9;0 (20 with developmental language disorder) and 60 adults, age range from 22 to 76. The accumulated results indicate that MAIN can differentiate narrative skills of speakers in distinct age groups and can distinguish children with language disorders form children with typical language development.

Purpose This study aimed to assess a protocol for the evaluation of developmental language disorder (DLD) in language minority bilingual children (LMBC). The specific aims were (a) to test group differences, (b) to evaluate the discriminant validity of single measures included in the protocol, and (c) to define which model of combined variables had the best results in terms of efficacy and efficiency. Method Two groups of LMBC were involved, one with typical development ( n = 35) selected from mainstream schools and one with DLD ( n = 20). The study protocol included the collection of demographic information and linguistic history; a battery of standardized tests in their second language (Italian), including nonword repetition, morphosyntactic comprehension and production, and vocabulary and narrative skills; and direct (children's evaluation) and indirect (parents' questionnaire) assessment of linguistic skills in their first language. Results Results showed that the two groups differed in almost all linguistic measures. None of the single measures reached good specificity/sensitivity scores. A combined model that included direct and indirect assessment of first language skills, morphosyntactic comprehension and production, and nonword repetition reached good discriminant validity, with 94.5% of cases correctly classified. Discussion The study defines a complex picture of the linguistic profile in bilingual children with DLD, compared to typically developing bilingual peers. The results reinforce the idea that no single measure can be considered optimal in distinguishing children with DLD from typical peers. The study offers a concrete example of an effective and efficient protocol with which to discriminate LMBC with and without DLD.

Language Background

Purpose A wealth of studies has assessed the diagnostic value of the nonword repetition task (NWRT) for the detection of developmental language disorder (DLD) in the clinical context of speech and language therapy, first in monolingual children and, more recently, in bilingual children. This review article reviews this literature systematically and conducts a meta-analysis on the discriminative power of this type of task in both populations. Method Three databases were used to select articles based on keyword combinations, which were then reviewed for relevance and methodological rigor based on internationally recognized checklists. From an initial pool of 488 studies, 46 studies were selected for inclusion in the systematic review, and 35 of these studies could be included in a meta-analysis. Results Most of the articles report significant discrimination between children with and without DLD in both monolingual and bilingual contexts, and the meta-analysis shows a large mean effect size. Three factors (age of the child, linguistic status, and language specificity of the task) yielded enough quantitative data for further exploration. Subgroups analysis shows variance in effect sizes, but none of the three factors, neither their interactions, were significant in a metaregression. We discuss how other, less explored factors (e.g., nature of the stimuli, scoring methods) could also contribute to differences in results. Sensitivity and specificity analyses reported in 33 studies confirmed that, despite possible effect size differences, the diagnostic accuracy of the NWRT is generally near thresholds considered to be discriminatory. It generally increases when it is combined with other tasks (e.g., parental questionnaire). Conclusions This review indicates that the NWRT is a promising diagnostic tool to identify children with DLD in monolingual and bilingual contexts with a large mean effect size. However, it seems necessary to choose the precise NWRT materials based on the children's language background and to complement the assessment sessions with other tools in order to ensure diagnosis and to obtain complete language profile of the child.
