The Acquisition of a Diglossic Language by Deaf and Hard of Hearing Students: Evidence From a Sentence Production Task.

PURPOSE: The current study aimed to examine morphosyntactic errors in sentences produced by DHH students, who are signers of Israeli Sign Language, and also users of Palestinian Colloquial Arabic (PCA) and written Modern Standard Arabic (MSA). METHOD: Nineteen school-age DHH students participated in a sentence elicitation task in which they retold events portrayed in 24 videos in PCA and MSA. A control group of 19 hearing students was tested with the same task. Sentences in each language variety were coded for grammatical versus ungrammatical productions and for type of morphosyntactic errors for the latter. In addition, code-switched words were counted. RESULTS: The hearing group showed no morphosyntactic errors, whereas the DHH students showed morphosyntactic errors in both PCA and MSA. In addition, both groups code-switched in both PCA and MSA, with more code-switching in the MSA task than in the PCA task. Furthermore, an interaction with age revealed that young students code-switched more in MSA and older students code-switched more in PCA. CONCLUSIONS: It is suggested that the morphosyntactic abilities of DHH students are incomplete in both language varieties. Lack of spoken language input may negatively influence the acquisition of spoken language, which impacts further the acquisition of the standard language in diglossic contexts. Code-switching is explained as both due to lexical gaps, when occurring in MSA, and an effort to raise the register in PCA.

Language in autism: domains, profiles and co-occurring conditions.

This article reviews the current knowledge state on pragmatic and structural language abilities in autism and their potential relation to extralinguistic abilities and autistic traits. The focus is on questions regarding autism language profiles with varying degrees of (selective) impairment and with respect to potential comorbidity of autism and language impairment: Is language impairment in autism the co-occurrence of two distinct conditions (comorbidity), a consequence of autism itself (no comorbidity), or one possible combination from a series of neurodevelopmental properties (dimensional approach)? As for language profiles in autism, three main groups are identified, namely, (i) verbal autistic individuals without structural language impairment, (ii) verbal autistic individuals with structural language impairment, and (iii) minimally verbal autistic individuals. However, this tripartite distinction hides enormous linguistic heterogeneity. Regarding the nature of language impairment in autism, there is currently no model of how language difficulties may interact with autism characteristics and with various extralinguistic cognitive abilities. Building such a model requires carefully designed explorations that address specific aspects of language and extralinguistic cognition. This should lead to a fundamental increase in our understanding of language impairment in autism, thereby paving the way for a substantial contribution to the question of how to best characterize neurodevelopmental disorders.

Referential expressions in monolingual and bilingual children with and without Autism Spectrum Disorder (ASD): A study of informativeness and definiteness.

The current study evaluated the separate and combined effects of bilingualism and Autism Spectrum Disorder (ASD) on informativeness and definiteness marking of referential expressions. Hebrew-speaking monolingual children (21 with ASD and 28 with typical language development) and Russian-Hebrew-speaking bilingual children (13 with ASD and 30 with typical language development) aged 4-9 years participated. Informativeness, indexed by referential contrasts, was affected by ASD, but not by bilingualism. Definiteness use was non-target-like in children with ASD and in bilingual children, and it was mainly predicted by children's morpho-syntactic abilities in Hebrew. Language-universal and language-specific properties of referential use are discussed.

Atypical phonological processes in naming errors of children with language impairment.

The current study explored the characteristics of phonological errors of preschool children with DLD (Developmental Language Disorder), distinguishing between typical versus atypical phonological processes in segmental, syllabic and word levels. The analysis included 87 responses of words with phonological errors from a naming test, produced by 13 preschool children with DLD, aged 4;4-6;3 years. These responses included 166 phonological processes, which were classified into typical and atypical processes at the levels of: segments, syllables, and prosodic words. The findings revealed that 70% of the phonological processes were atypical. Furthermore, ten children produced more atypical processes, and there were more atypical than typical processes in segmental and word levels. It is suggested that some children with DLD represent phonological processes that are similar to those that children with speech and sound disorders produce. Therefore, clinically, the results emphasise the importance of analysing the typical and atypical characteristics of phonological errors as part of language assessment.

Influences of bilingualism and developmental language disorder on how children learn and process words.

Previous studies found that bilingual children and adults with typical language development (TLD) perform better than monolinguals in novel word learning, but show lower scores on lexical retrieval tasks (e.g., naming known words). Children with developmental language disorder (DLD) lack in their abilities in both tasks compared with children with TLD. The current study tested the interplay between bilingualism and language disorder during novel word learning and lexical retrieval. Preschoolers (N = 101; 50 boys and 51 girls; mothers' mean years of education = 16.35) in four groups (Hebrew monolinguals or Russian-Hebrew bilinguals with DLD or TLD) learned 12 novel real words (6 with a familiar referent and 6 with a novel referent) and performed a lexical retrieval task. Children exhibited significant learning with no effect of bilingualism, but a negative effect of language disorder. Thus, children with DLD performed worse than children with TLD, and this ability was not affected by bilingualism. In lexical retrieval, DLD groups scored lower than TLD groups, and critically also bilinguals scored lower than monolinguals. This differential effect of bilingualism in the two tasks suggests that bilingualism does not impede language learning mechanisms even among children with DLD. Instead, the findings suggest that lower performance in the lexical retrieval task is due to decreased frequency of exposure. By exploring both word learning and lexical retrieval, the study highlights the differential mechanisms at play in the effects of bilingualism and language disorder on the developing lexicon.

Talking While Signing: The Influence of Simultaneous Communication on the Spoken Language of Bimodal Bilinguals.

PURPOSE: This study aimed to examine how speech while sign (simultaneous communication [SimCom]) affects the spoken language of bimodal bilingual teachers and how individual differences in sign-language vocabulary knowledge, SimCom teaching experience, and the ability to perform speech under dual-task conditions explain the variability in SimCom performance. METHOD: Forty experienced teachers of deaf and hard of hearing students participated in a story narration task under different conditions. Speech rate, lexical richness, and syntactic complexity were measured and compared across speech-only versus SimCom conditions. Furthermore, participants' score on a sign-language vocabulary test, their self-reported SimCom teaching experience, and their performance in a dual-task condition were taken as predictors of SimCom narration performance. RESULTS: The findings revealed slower speech rate, lower lexical richness, and lower syntactic complexity in the SimCom condition compared with the speech-only condition. Sign-language vocabulary score and SimCom teaching experience explained speech rate and lexical richness. Participant's ability to speak under a dual-task condition did not modulate performance. CONCLUSIONS: The findings may suggest that the production of the less dominant (sign) language during SimCom entails inhibition of the dominant (spoken) language relative to the speech-only condition. At the same time, the findings are also compatible with the suggestion that SimCom serves as a unique complex communication unit that cannot be reduced to the combination of two languages.

Deaf Children's ASL Vocabulary and ASL Syntax Knowledge Supports English Knowledge.

The current study contributes empirical data to our understanding of how knowledge of American Sign Language (ASL) syntax aids reading print English for deaf children who are bilingual and bimodal in ASL and English print. The first analysis, a conceptual replication of Hoffmeister ( 2000), showed that performance on the American Sign Language Assessment Instrument correlated with the Sanford Achievement Test-Reading Comprehension (SAT-RC) and the Rhode Island Test of Language Structures (RITLS, Engen & Engen, 1983). The second analysis was a quantile regression using ASL assessments to predict English print abilities. Different ASL skills were important for English reading comprehension (SAT-RC) versus understanding English syntax (RITLS); the relationship between ASL skills and English print performance also varied for students at different English print ability levels. Strikingly, knowledge of ASL syntax was robustly correlated with knowledge of English syntax at all ability levels. Our findings provide novel and strong evidence for the impact of ASL on the development of English literacy.

"So, I told him to look for friends!" Barriers and protecting factors that may facilitate inclusion for children with Language Disorder in everyday social settings: Cross-cultural qualitative interviews with parents.

PURPOSE: Although researchers have explored parental perspectives on childhood speech and language disorders, this work has mostly been conducted in English-speaking countries. Little is known about parental experiences across countries. Participation in the COST Action IS1406 'Enhancing children's oral language skills across Europe and beyond' provided an opportunity to conduct cross-cultural qualitative interviews. The aims were to explore how parents construe inclusion and/or exclusion of their child and how parents involve themselves in order to facilitate inclusion. METHOD: Parents from nine countries and with a child who had received services for speech-language disorder participated in semi-structured qualitative interviews. We used thematic analysis to analyze the data. RESULTS: Two overarching themes were identified: 'Language disabilities led to social exclusion' and 'Promoting pathways to social inclusion'. Two subthemes were identified Interpersonal relationships are important and Deliberate proactiveness as stepping stones for social inclusion. CONCLUSIONS: Across countries, parents report that their children's hidden disability causes misunderstandings that can lead to social exclusion and that they are important advocates for their children. It is important that the voices and experiences of parents of children with developmental disabilities are understood and acknowledged. Parents' recommendations about how to support social inclusion need to be addressed at all levels of society.

Exploring Parental Perspectives of Childhood Speech and Language Disorders Across 10 Countries: A Pilot Qualitative Study.

Purpose Although researchers have explored parental perspectives of childhood speech and language disorders, most studies have been conducted in English-speaking countries. Little is known about parental experiences across countries, where procedures of language screening and services for language disorders differ. The authors participated in the COST 1 Action network IS1406, "Enhancing Children's Oral Language Skills Across Europe and Beyond," which provided an opportunity to conduct cross-country qualitative interviews with parents. The aim of this pilot study was to explore ways in which parents construed and described speech and language disorders across countries. Method Semistructured qualitative interviews were conducted with parents from 10 families in 10 different countries. The data were analyzed using thematic analysis. Findings The overall theme was "acknowledging parental expertise." The parents described, in detail, ways in which their children's speech and language (dis)abilities had an impact on the children's everyday life. Three subthemes were identified: impairment, disability, and changes over time. Conclusions The findings suggest that, across a range of countries, parents demonstrated contextualized understandings of their children's speech and language (dis)abilities, along with the everyday functional implications of the disorders. Hence, despite not holding professional knowledge about language disorders, the voices, views, understandings, and personal experiences of parents in relation to their child's disorder should be listened to when planning therapy services.

Prerequisites of Third-Person Pronoun Use in Monolingual and Bilingual Children With Autism and Typical Language Development.

The current study investigated the production of third-person subject and object pronouns in monolingual and bilingual children with High Functioning Autism (HFA) and typical language development (TLD). Furthermore, it evaluated the underlying linguistic and non-linguistic prerequisites of pronoun use, by assessing the role of morpho-syntactic skills, Theory of Mind (ToM) abilities, working memory and inhibition on pronoun use. A total of 85 children aged 4 to 9 years participated in four groups: 27 children with HFA [14 monolingual (monoHFA) and 13 bilingual (biHFA)], and 58 children with TLD [28 monolingual (monoTLD) and 30 bilingual (biTLD)]. All children spoke Hebrew and the bilingual children spoke Russian as their Heritage Language. Third-person subject and object pronouns were elicited in Hebrew. The results yielded no effect of bilingualism, and a robust effect of HFA on the use of pronouns. Bilingual Russian-Hebrew speaking children paired up with their monolingual Hebrew-speaking peers in pronominal use in Hebrew. Monolingual and bilingual children with TLD showed nearly ceiling performance on pronoun use. The facilitative effect of pronominal acquisition in Hebrew among bilingual children was attributed to similarities in the pronominal systems of the two languages of bilingual children. Age was found to be a predictive factor of pronoun use in children with TLD. Conversely, children with HFA had a lower rate of pronoun production compared to the TLD groups. Both third-person subject and object pronouns were largely predicted by morpho-syntactic abilities of children with HFA. In addition, subject pronoun use was predicted by ToM skills and working memory confirming that pronoun use is a complex phenomenon, which requires integration of multiple linguistic and non-linguistic components. To conclude, our findings suggest that morpho-syntactic development is a prerequisite for third-person subject and object pronoun use in children with HFA, and ToM and working memory are involved in third-person subject pronoun use. In addition, we show that pronoun use is not compromised by dual language exposure in children with TLD and with HFA.

The joint effects of bilingualism, DLD and item frequency on children's lexical-retrieval performance.

BACKGROUND: Bilingual children and children diagnosed with developmental language disorder (DLD) are characterized by reduced lexical-retrieval abilities. Few studies examined their joint contribution and the mechanisms underlying these effects in the lexical domain. AIMS: To explore the joint effects of bilingualism and DLD by adopting a four-group comparison in which the difference between bi- and monolingual children with DLD is directly compared with that of bi- and monolingual children with typical language development (TLD). In addition, to examine the mechanisms underlying the effects of bilingualism and DLD on children's lexical-retrieval abilities, we tested how item's characteristics (frequency of use) modulate the effects of bilingualism and DLD. METHODS & PROCEDURES: Fifty-eight children (aged 9-14 years) participated in the current study. They were either Hebrew monolingual or Hebrew-English bilinguals and were either diagnosed with DLD or had TLD. Children completed a Hebrew picture-naming task and verbal short-term memory tests. The influence of participants' characteristics, including bilingualism, DLD and verbal short-term memory, as well as item's characteristics (frequency of use) were tested. OUTCOMES & RESULTS: Accuracy analysis revealed that bilingual children scored lower than monolingual children and that children with DLD scored lower than children with TLD. Critically, the two factors interacted such that their joint presence resulted in less-than-additive effects. Specifically, although bilingual children with DLD performed worse than all other groups, they performed better than expected under an additive model. Interestingly, monolingual children with DLD performed similarly to bilingual children with TLD. Increased verbal short-term memory was associated with better performance across the four groups. Finally, bilingualism and DLD interacted with item frequency, such that being bilingual, having DLD, or both, resulted in increased sensitivity to item frequency manifested in exceptionally lower performance on low-frequency items. CONCLUSIONS & IMPLICATIONS: The findings suggest that the strength of linguistic representations contribute to the effects of bilingualism and DLD. Further, the presence of bilingualism in the context of DLD does not exaggerate the impact of DLD. Clinically, this suggests that differences between bi- and monolingual children with DLD must be considered in reference to the gap in lexical-retrieval performance observed between bi- and monolingual children with TLD. Finally, because monolingual children with DLD and bilingual children with TLD performed similarly, sensitive diagnostic tools and intervention programmes should be adopted to allow correct identification and treatment of bilingual children with DLD.

The Development of American Sign Language-Based Analogical Reasoning in Signing Deaf Children.

Purpose This article examines whether syntactic and vocabulary abilities in American Sign Language (ASL) facilitate 6 categories of language-based analogical reasoning. Method Data for this study were collected from 267 deaf participants, aged 7;6 (years;months) to 18;5. The data were collected from an ongoing study initially funded by the U.S. Institute of Education Sciences in 2010. The participants were given assessments of ASL vocabulary and syntax knowledge and a task of language-based analogies presented in ASL. The data were analyzed using mixed-effects linear modeling to first see how language-based analogical reasoning developed in deaf children and then to see how ASL knowledge influenced this developmental trajectory. Results Signing deaf children were shown to demonstrate language-based reasoning abilities in ASL consistent with both chronological age and home language environment. Notably, when ASL vocabulary and syntax abilities were statistically taken into account, these were more important in fostering the development of language-based analogical reasoning abilities than were chronological age and home language. We further showed that ASL vocabulary ability and ASL syntactic knowledge made different contributions to different analogical reasoning subconstructs. Conclusions ASL is a viable language that supports the development of language-based analogical reasoning abilities in deaf children.

Recent Issues in the Use of Signed Language Assessments for Diagnosis of Language Disorders in Signing Deaf and Hard of Hearing Children.

In recent years, normed signed language assessments have become a useful tool for researchers, practitioners, and advocates. Nevertheless, there are limitations in their application, particularly for the diagnosis of language disorders, and learning disabilities. Here, we discuss some of the available normed, signed language assessments and some of their limitations. We have also provided information related to practices that should lead to improvement in the quality of signed language assessments.

Morphosyntactic abilities of toddlers with hearing impairment and normal hearing: evidence from a sentence-repetition task.

BACKGROUND: While considerable research exists on morphosyntax of school-age children with hearing impairment (HI), little is known about development of morphosyntax at younger ages. Some studies show that young children with HI have a delay in language abilities compared with children with normal hearing (NH); conversely, other studies show evidence that they achieve age-appropriate language development. AIMS: To investigate whether characteristics of morphosyntactic development displayed by young children with HI are unique or whether they are similar to those of NH children. METHODS & PROCEDURES: Fifty-four Hebrew-speaking children (15 with HI and 39 with NH), aged 22-40 months, completed a novel Hebrew sentence repetition (SRep) task designed to evaluate morphosyntactic abilities. Accuracy on the total correct structure, repetition of content and function words, and repetition of specific morphemes were compared across groups. OUTCOMES & RESULTS: At the earliest stages of combining words to sentences, toddlers in both groups showed a large variation in morphosyntactic development, with no significant difference between the two groups. Children with HI and NH showed similar results for the acquisition of morphemes and various syntactic structures. In the group of children with HI, hearing capability accounted for 28% of the variance of the SRep task. CONCLUSIONS & IMPLICATIONS: The findings suggest typical morphosyntax capacity at the onset of language development among of children with HI who are diagnosed early and receive intensive intervention.

What we can learn from naming errors of children with language impairment at preschool age.

Naming is a complex, multi-level process. It is composed of distinct semantic and phonological levels. Children with naming deficits produce different error types when failing to retrieve the target word. This study explored the error characteristics of children with language impairment compared to those with typical language development. 46 preschool children were tested on a naming test: 16 with language impairment and a naming deficit and 30 with typical language development. The analysis compared types of error in both groups. In a group level, children with language impairment produced different error patterns compared to the control group. Based on naming error analysis and performance on other language tests, two case studies of contrasting profiles suggest different sources for lexical retrieval difficulties in children. The findings reveal differences between the two groups in naming scores and naming errors, and support a qualitative impairment in early development of children with naming deficits. The differing profiles of naming deficits emphasise the importance of including error analysis in the diagnosis.

American Sign Language Syntax and Analogical Reasoning Skills Are Influenced by Early Acquisition and Age of Entry to Signing Schools for the Deaf.

Failing to acquire language in early childhood because of language deprivation is a rare and exceptional event, except in one population. Deaf children who grow up without access to indirect language through listening, speech-reading, or sign language experience language deprivation. Studies of Deaf adults have revealed that late acquisition of sign language is associated with lasting deficits. However, much remains unknown about language deprivation in Deaf children, allowing myths and misunderstandings regarding sign language to flourish. To fill this gap, we examined signing ability in a large naturalistic sample of Deaf children attending schools for the Deaf where American Sign Language (ASL) is used by peers and teachers. Ability in ASL was measured using a syntactic judgment test and language-based analogical reasoning test, which are two sub-tests of the ASL Assessment Inventory. The influence of two age-related variables were examined: whether or not ASL was acquired from birth in the home from one or more Deaf parents, and the age of entry to the school for the Deaf. Note that for non-native signers, this latter variable is often the age of first systematic exposure to ASL. Both of these types of age-dependent language experiences influenced subsequent signing ability. Scores on the two tasks declined with increasing age of school entry. The influence of age of starting school was not linear. Test scores were generally lower for Deaf children who entered the school of assessment after the age of 12. The positive influence of signing from birth was found for students at all ages tested (7;6-18;5 years old) and for children of all age-of-entry groupings. Our results reflect a continuum of outcomes which show that experience with language is a continuous variable that is sensitive to maturational age.

What can errors tell us about specific language impairment deficits? Semantic and morphological cuing in a sentence completion task.

The lexical retrieval ability of children with specific language impairment (SLI) and children with typical language development was compared. Fifty Hebrew-speaking children participated: 15 school-age with SLI, 20 typically developing, matched on age to the SLI group and 15 younger, typically developing matched on naming performance to the SLI group. Participants were tested in a sentence completion task with semantic cuing and with morphological cuing. SLI children performed poorer than the chronological-age group and similarly to the naming-matched group. Error patterns showed a qualitative difference between the SLI and naming-matched groups. The results suggest that lexical retrieval of children with SLI is delayed and qualitatively different from that of typically developing children.

Subject pronoun use by children with autism spectrum disorders (ASD).

In the current study, storytelling and story retelling by children with autism spectrum disorder (ASD) were analyzed to explore ambiguous third-person pronoun use in narratives. Twenty-three children diagnosed with ASD aged 6;1 to 14;3 and 17 typically-developing (TD) children aged 5;11 to 14;4 participated in the study. In the retelling task, no significant difference between the groups was found, suggesting that in less challenging tasks, children with ASD produce third-person subject pronouns appropriately. In the storytelling task, children with ASD produced more ambiguous third-person subject pronouns than did the TD children. The findings suggest a model in which children with ASD show deficits in the pragmatic domain of producing narratives.

Is the movement deficit in syntactic SLI related to traces or to thematic role transfer?

Children with Syntactic Specific Language Impairment (S-SLI) have difficulties understanding object relative clauses, which have been ascribed to a deficit in syntactic movement. The current study explores the nature of the deficit in movement, and specifically whether it is related to a deficit in the construction of syntactic structure and traces, or whether the structure is constructed correctly but the transfer of thematic roles from the trace is impaired. This question was addressed using reading aloud and paraphrasing of object relatives that included noun-verb heterophonic homographs after the trace. Because the correct reading of homographs as noun or verb critically hinges on the identification of their syntactic position, readers who cannot construct traces are expected to read homographs incorporated after the trace incorrectly. The participants were 15 Hebrew-speaking children aged 9.3 to 14.6 with S-SLI and 50 typically developing children. The children with S-SLI read the homographs after the trace correctly but failed to interpret the object relatives, making thematic role errors. The results suggest that in S-SLI, at least for school-aged children, syntactic structure and traces are created, but the assignment of thematic roles from the trace to the moved element is impaired, leading to a deficit in the comprehension of movement-derived sentences.

The acquisition of relative clause comprehension in Hebrew: a study of SLI and normal development.

Comprehension of relative clauses was assessed in 10 Hebrew-speaking school-age children with syntactic SLI and in two groups of younger children with normal language development. Comprehension of subject- and object-relatives was assessed using a binary sentence-picture matching task. The findings were that while Hebrew-speaking children with normal development comprehend right-branching object relatives around the age of 6 ; 0, children with syntactic SLI are still at chance level in object relatives by age 11 ; 0. The four-year-olds were also at chance on object relatives. Comprehension of subject relatives was good in the SLI group, similar to the six-year-olds, and significantly better than the four-year-olds. The syntactic impairment is interpreted as a selective deficit to non-canonical sentences that are derived by movement.
