Repetition Task

Purpose: Research on the typical and impaired grammatical acquisition of Arabic is limited. This study systematically examined the morphosyntactic abilities of Arabic-speaking children with and without developmental language disorder (DLD) using a novel sentence repetition task. The usefulness of the task as an indicator of DLD in Arabic was determined. Method: A LITMUS (Language Impairment Testing in Multilingual Settings) sentence repetition task was developed in Palestinian Arabic (LITMUS-SR-PA-72) and administered to 30 children with DLD ( M = 61.50 months, SD = 11.27) and 60 age-matched typically developing (TD) children ( M = 63.85 months, SD = 10.16). The task targeted grammatical structures known to be problematic for Arabic-speaking children with DLD (language specific) and children with DLD across languages (language independent). Responses were scored using binary, error, and structural scoring methods. Results: Children with DLD scored below TD children on the LITMUS-SR-PA-72, in general, and in the repetition of language-specific and language-independent structures. The frequency of morphosyntactic errors was higher in the DLD group relative to the TD group. Despite the large similarity of the type of morphosyntactic errors between the two groups, some atypical errors were exclusively produced by the DLD group. The three scoring methods showed good diagnostic power in the discrimination between children with DLD and children without DLD. Conclusions: Sentence repetition was an area of difficulty for Palestinian Arabic–speaking children with DLD. The DLD group demonstrated difficulties with language-specific and language-independent structures, particularly complex sentences with noncanonical word order. Most grammatical errors made by the DLD group resembled those of the TD group and were mostly omissions or substitutions of grammatical affixes or omissions of function words. SR appears to hold promise as a good indicator for the presence or absence of DLD in Arabic. Further validation of these findings using population-based studies is warranted.

Purpose This study investigated the production of tense and subject–verb agreement in Palestinian Arabic–speaking children with developmental language disorder (DLD) in comparison to their typically developing (TD) peers in terms of (a) performance accuracy and (b) error patterns. Method Participants were 14 children with DLD aged 4;0–7;10 and 32 TD children aged 3;0–8;0 matched on nonverbal abilities. Children were asked to complete a picture-based verb elicitation task. The task was designed to measure the production accuracy of tense and subject–verb agreement inflections in Arabic. Results The DLD group scored significantly lower than the TD group on the verb elicitation task. The DLD group was significantly less accurate than the TD group in marking tense, specifically present tense. They were also less accurate in marking agreement in general, with specific difficulty in using feminine verb forms. The DLD and TD groups differed in their tense error patterns, but not in agreement error patterns. Conclusions The acquisition of verb morphology in Palestinian Arabic–speaking children with DLD appears to be delayed and possibly different from their TD peers. The DLD group found the production of marked verb forms more challenging than less marked ones. These results are discussed in light of the structural characteristics of Arabic. Future studies would need to include larger sample sizes; investigate other aspects of verb morphology, including both production and comprehension; include other language domains; and consider longitudinal designs to provide more in-depth knowledge of Arabic language acquisition.

Purpose This study evaluates the effectiveness of a nonword repetition (NWR) task in discriminating between Palestinian Arabic–speaking children with developmental language disorder (DLD) and age-matched typically developing (TD) children. Method Participants were 30 children with DLD aged between 4;0 and 6;10 (years;months) and 60 TD children aged between 4;0 and 6;8 matched on chronological age. The Arabic version of a Quasi-Universal NWR task was administered. The task comprises 30 nonwords that vary in length, presence of consonant clusters (CCs) and wordlikeness ratings. Responses were scored using an item-level scoring method to assess the diagnostic accuracy of the task. Receiver operating characteristic curve analysis was conducted to determine the best cutoff point with the highest sensitivity and specificity values, and likelihood ratios were calculated. Results Children with DLD scored significantly lower on the NWR task than their age-matched TD peers. Only the DLD group was influenced by the phonological complexity of the nonwords, with nonwords with two CC being more difficult than nonwords with no or only one CC. For both groups, three-syllable nonwords were repeated less accurately than two- and one-syllable nonwords. Also, high word-like nonwords were repeated more accurately than nonwords with low wordlikeness ratings. The best cutoff score had sensitivity and specificity of 93% and highly informative likelihood ratios. Conclusions NWR was an area of difficulty for Palestinian Arabic–speaking children with DLD. NWR showed excellent discriminatory power in differentiating Arabic-speaking children diagnosed with DLD from their age-matched TD peers. NWR appears to hold promise for clinical use as it is a useful indicator of DLD in Arabic. These results need to be further validated using population-based studies.

Sentence repetition tasks (SRTs) have been widely used in language development research for decades. In recent years, there has been increasing interest in studying performance in SRTs as a clinical marker for language impairment. What are the characteristics of SRTs? For what purposes have SRTs been used? To what extent have they been used with young children, in different languages, and with different clinical populations? In order to answer these and other questions, we conducted a scoping review. Peer reviewed studies published in indexed scientific journals (2010–2021) were analyzed. A search in different databases yielded 258 studies. Research published in languages other than English or Spanish, adult samples, dissertations, case studies, artificial models, and theoretical publications were excluded. After this exclusion, 203 studies were analyzed. Our results show that most research using SRT were conducted with English monolingual speakers older than 5 years of age; studies with bilingual participants have mostly been published since 2016; and SRTs have been used with several non-typical populations. Research suggests that they are a reliable tool for identifying language difficulties and are specifically suitable for detecting developmental language disorder.

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.

Purpose The purpose of this article is to situate the recent language disorder label debate within a school's perspective. As described in two recent The ASHA Leader articles, there is international momentum to change specific language impairment to developmental language disorder . Proponents of this change cite increased public awareness and research funding as part of the rationale. However, it is unclear whether this label debate is worthwhile or even practical for the school-based speech-language pathologist (SLP). A discussion of the benefits and challenges to a shift in language disorder labels is provided. Conclusions Although there are important arguments for consistency in labeling childhood language disorder, the reality of a label change in U.S. schools is hard to imagine. School-based services are driven by eligibility through the Individuals with Disabilities Education Act, which has its own set of labels. There are myriad reasons why advocating for the developmental language disorder label may not be the best use of SLPs' time, perhaps the most important of which is that school SLPs have other urgent priorities.

Purpose The current “specific language impairment” and “developmental language disorder” discussion might lead to important changes in how we refer to children with language disorders of unknown origin. The field has seen other changes in terminology. This article reviews many of these changes. Method A literature review of previous clinical labels was conducted, and possible reasons for the changes in labels were identified. Results References to children with significant yet unexplained deficits in language ability have been part of the scientific literature since, at least, the early 1800s. Terms have changed from those with a neurological emphasis to those that do not imply a cause for the language disorder. Diagnostic criteria have become more explicit but have become, at certain points, too narrow to represent the wider range of children with language disorders of unknown origin. Conclusions The field was not well served by the many changes in terminology that have transpired in the past. A new label at this point must be accompanied by strong efforts to recruit its adoption by clinical speech-language pathologists and the general public.

Purpose The aim of the study was to explore the potential of performance on a Danish sentence repetition (SR) task—including specific morphological and syntactic properties—to identify difficulties in children with developmental language disorder (DLD) relative to typically developing (TD) children. Furthermore, the potential of the task as a clinical marker for Danish DLD was explored. Method SR performance of children with DLD aged 5;10–14;1 (years;months; n = 27) and TD children aged 5;3–13;4 ( n = 87) was investigated. Results Compared to TD same-age peers, children with DLD were less likely to repeat the sentences accurately but more likely to make ungrammatical errors with respect to verb inflection and use of determiners and personal pronouns. Younger children with DLD also produced more word order errors that their TD peers. Furthermore, older children with DLD performed less accurately than younger TD peers, indicating that the SR task taps into morphosyntactic areas of particular difficulty for Danish children with DLD. The classification accuracy associated with SR performance showed high levels of sensitivity and specificity (> 90%) and likelihood ratios indicating good identification potential for clinical and future research purposes. Conclusion SR performance has a strong potential for identifying children with DLD, also in Danish, and with a carefully designed SR task, performance has potential for revealing morphosyntactic difficulties.

Developmental Conditions

Language and communication deficits characterize both autism spectrum disorder and developmental language disorder, and the possibility of there being a common profile of these is a matter of tireless debate in the research community. This experimental study addresses the relation of these two developmental conditions in the critical topic of language. Α total of 103 children (79 males, 24 females) participated in the present study. Specifically, the study’s sample consisted of 40 children with autism, 28 children with developmental language disorder, and 35 typically developing children between 6 and 12 years old. All children completed language and cognitive measures. The results showed that there is a subgroup inside the autism group of children who demonstrate language difficulties similar to children with developmental language disorder. Specifically, two different subgroups were derived from the autism group; those with language impairment and those without. Both autism and language-impaired groups scored lower than typically developing children on all language measures indicating a common pathology in language ability. The results of this study shed light on the relation between the two disorders, supporting the assumption of a subgroup with language impairment inside the autism spectrum disorder population. The common picture presented by the two developmental conditions highlights the need for further research in the field.

Insight Into

This chapter provides an overview of the evidence on grammatical number processing taken from cognitive neuropsychology, including developmental delays and impairments of language (e.g. developmental language disorder, and Williams syndrome) and aphasia, an acquired language impairment after brain injury. These types of language impairment can give insight into the functional architecture of nominal number processing by looking at error patterns that arise in each of the aforementioned populations. By classifying observed responses in language production tasks into non-number and number errors, we are able to reveal underlying mechanisms of syntactic rules and their representations when they develop, but also learn about processes and representation of number when this information breaks down.

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.
