Sentence Repetition as a Clinical Marker of Developmental Language Disorder: Evidence From Arabic

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.

Argument omissions by deaf students in three languages and three modalities

While it is common for deaf children to be bilingual in a spoken and signed language, studies often attribute any delays in language acquisition to language deprivation, rather than as a result of cross-linguistic interaction. This study compares the production of simple sentences in three languages (Palestinian Arabic, Modern Standard Arabic, and Israeli Sign Language [ISL]) and three language modalities (spoken, written, and signed) by deaf and hearing students in an Arabic-speaking community. Thirty-eight school-age Palestinian Arabic–speaking students participated in a sentence elicitation task in which they retold the events portrayed in video clips. Hearing students ( n = 19) produced the sentences in spoken Palestinian Arabic and in written Modern Standard Arabic. Deaf students ( n = 19) produced the sentences in these two language varieties and additionally in ISL. Omissions of arguments and verbs were compared across the two groups and three languages. Results showed that deaf students omitted more arguments and verbs compared with their hearing peers who scored at close to ceiling. Deaf students produced more omissions for direct objects and more omissions in ISL. The findings can be interpreted in two possible ways: atypical effects resulting from inconsistent language input and cross-linguistic transfer known to arise in multilingual children.

Nonword Repetition Performance of Arabic-Speaking Children With and Without Developmental Language Disorder: A Study on Diagnostic Accuracy

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.

Palestinian Arabic versus Israeli Hebrew Place-Names: Comparative Cultural Reading of Landscape Nomenclature and Israeli Renaming Strategies

This article compares Palestinian (Arabic) and Israeli (Hebrew) names of natural features in Palestine/Israel. Based on postcolonial reading and critical toponymy, I argue that despite the dominance of the Jewish nationalist narrative the nomenclature includes ‘intermediate categories’ that attest to subversive linguistic practices, bottom-up communication aspects, and sociocultural realities. These aspects are analysed through five main categories: unification; uniqueness; male rhetoric replacing female identity; sanitization; and linguistic imitation. The article adds to the literature largely focused on the political aspect of the Jewish settlement names that replaced Palestinian names in that it shows how Zionist naming of natural features included the cultural perspectives of the Palestinian names in order to appropriate them for internal Jewish cultural needs.

(No) variation in the grammar of alternatives

The paper reports the results of an in-depth crosslinguistic study of intervention effects and the grammar of alternatives in a typologically diverse sample of five languages: Palestinian Arabic (Afro-Asiatic, Semitic), Russian (Indo-European, Slavic), Samoan (Austronesian, Oceanic), Turkish (Altaic, Turkic), and Yoruba (Niger-Congo, Defoid). In all of these languages, we find an interesting asymmetry in that focus evaluation interrupts question evaluation and causes an intervention effect, but not vice versa. We take our data to inform the crosslinguistic analysis of two alternative-evaluating operators, the squiggle operator and the question operator. To capture the observed absence of variation, we propose two semantic universals: The squiggle operator unselectively evaluates all alternatives in its scope. The question operator, on the other hand, is selective.

Expressive Verb Morphology Deficits in Arabic-Speaking Children With Developmental Language Disorder

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.
