Titre : Impaired praxis in gesture imitation by deaf children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Aaron SHIELD, Auteur ; Krista KNAPKE, Auteur ; Morgan HENRY, Auteur ; Sudha SRINIVASAN, Auteur ; Anjana N. BHAT, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background and aimsPraxis, the ability to plan and execute a series of gestures or motor sequences, is impaired in individuals with autism spectrum disorder. In this paper, we present the first study of praxis during a gesture imitation task in a unique population of children with autism spectrum disorder: deaf children who have been exposed to American Sign Language from birth by their Deaf parents. Lifelong exposure to sign language in deaf individuals entails practice with gesture imitation. We ask if deaf, signing children with autism spectrum disorder present with praxis impairments similar to those reported in the literature for hearing children with autism spectrum disorder not exposed to sign.MethodsThirty deaf children of Deaf parents (16 typically developing and 14 with autism spectrum disorder), matched for chronological and mental age, were tested on a simple gesture imitation task. Children were asked to imitate 24 gestures performed by an adult model on a laptop computer that varied along dimensions of movement type (16 trials) and palm orientation direction (eight trials). Data were coded for nine praxis parameters (five formation parameters and four manner parameters) and three timing measures.ResultsResults showed that the deaf children with autism spectrum disorder produced more errors than the typically developing deaf children on six of the nine praxis dimensions (hand orientation, final orientation, modulation, directness, pace, and overflow) and were more impaired on manner parameters than formation parameters, suggesting underlying deficits in motor control/coordination leading to dyspraxia. Praxis scores were strongly related to severity of autism spectrum disorder symptoms and receptive sign language scores.ConclusionsWe thus find evidence that praxis is impaired in deaf, signing children with autism spectrum disorder, despite lifelong exposure to a gestural language and extensive practice with gesture imitation.ImplicationsOur findings suggest that interventions targeted toward enhancing praxis and coordination of finger and hand movements could help facilitate language development in children with autism spectrum disorder.

Titre : Relations between language and cognition in native-signing children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Aaron SHIELD, Auteur ; Jennie PYERS, Auteur ; Amber MARTIN, Auteur ; Helen TAGER-FLUSBERG, Auteur Article en page(s) : p.1304-1315 Langues : Anglais (eng) Mots-clés : theory of mind social cognition developmental psychology cognitive neuroscience Index. décimale : PER Périodiques Résumé : Two populations have been found to exhibit delays in theory of mind (ToM): deaf children of hearing parents and children with autism spectrum disorder (ASD). Deaf children exposed to sign from birth by their deaf parents, however, show no such delay, suggesting that early language exposure is key to ToM development. Sign languages also present frequent opportunities with visual perspective-taking (VPT), leading to the question of whether sign exposure could benefit children with ASD. We present the first study of children with ASD exposed to sign from birth by their deaf parents. Seventeen native-signing children with a confirmed ASD diagnosis and a chronological- and mental age-matched control group of 18 typically developing (TD) native-signing deaf children were tested on American Sign Language (ASL) comprehension, two minimally verbal social cognition tasks (ToM and VPT), and one spatial cognition task (mental rotation). The TD children outperformed the children with ASD on ASL comprehension (p?0.0001), ToM (p?=?0.02), and VPT (p?0.01), but not mental rotation (p?=?0.12). Language strongly correlated with ToM (p?0.01) and VPT (p?0.001), but not mental rotation (p?=?ns). Native exposure to sign is thus insufficient to overcome the language and social impairments implicated in ASD. Contrary to the hypothesis that sign could provide a scaffold for ToM skills, we find that signing children with ASD are unable to access language so as to gain any potential benefit sign might confer. Our results support a strong link between the development of social cognition and language, regardless of modality, for TD and ASD children.

Titre : The Production of Pronouns and Verb Inflections by Italian Children with ASD: A New Dataset in a Null Subject Language Type de document : Texte imprimé et/ou numérique Auteurs : Greta MAZZAGGIO, Auteur ; Aaron SHIELD, Auteur Article en page(s) : p.1425-1433 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Language development Pronoun avoidance Pronoun production Index. décimale : PER Périodiques Résumé : The language of children with autism spectrum disorder (ASD) is often characterized by difficulties with pronouns. The underlying reasons for such difficulties are still unclear. This study is the first to test the abilities of children with ASD who speak Italian, a language in which overt subject pronouns are optional but verbs obligatorily feature person-referencing morphology. We found that Italian children with ASD were less accurate than typically-developing (TD) Italian children in the production of first-, second-, and third-person singular pronouns, avoiding pronouns in favor of nouns or names more often than controls. Moreover, children with ASD produced more overt pronouns than null pronouns in marked contexts, compared to TD children. These phenomena can be accounted for by difficulties with pragmatics.

MEIER, Auteur ; Helen TAGER-FLUSBERG, Auteur Année de publication : 2015 Article en page(s) : p.2128-2145 Langues : Anglais (eng) Mots-clés : Sign language Autism spectrum disorder Deafness Pronouns Language development Index. décimale : PER Périodiques Résumé : We report the first study on pronoun use by an under-studied research population, children with autism spectrum disorder (ASD) exposed to American Sign Language from birth by their deaf parents. Personal pronouns cause difficulties for hearing children with ASD, who sometimes reverse or avoid them. Unlike speech pronouns, sign pronouns are indexical points to self and other. Despite this transparency, we find evidence from an elicitation task and parental report that signing children with ASD avoid sign pronouns in favor of names. An analysis of spontaneous usage showed that all children demonstrated the ability to point, but only children with better-developed sign language produced pronouns. Differences in language abilities and self-representation may explain these phenomena in sign and speech.
