“…Fowler, 1990;Laws & Bishop, 2003). Individuals with DS have been found to perform significantly worse than TD children, particularly on comprehension of anaphors (Perovic, 2006) and passives (Ring & Clahsen, 2005), leading researchers to suggest that the language of children with DS is qualitatively different. Oakes, Kover and Abbeduto (2013) investigated the sentence comprehension of young adolescents with DS and reported that they performed significantly worse than TD children who were matched on non-verbal IQ scores.…”

Purpose: The study aims to describe receptive language skills in children with intellectual disability (ID) and to contribute to the debate on deviant vs. delayed language development. This is the first study of receptive skills in children with ID who speak a Slavic language, providing insight into how language development is affected by disability and also language typology.Method: Twenty-eight Slovak-speaking children participated in the study (14 children with ID and 14 typically developing (TD) children matched on non-verbal reasoning abilities). The children were assessed by receptive language tasks targeting words, sentences and stories, and the groups were compared quantitatively and qualitatively.Results: The groups showed similar language profiles, with a better understanding of words, followed by sentences, with the poorest comprehension for stories. Nouns were comprehended better than verbs; sentence constructions also showed a qualitatively similar picture, although some dissimilarities emerged. Verb comprehension was strongly related to sentence comprehension in both groups, and related to story comprehension in the TD group only.Conclusions: The findings appear to support the view that receptive language skills follow the same developmental route in children with ID as seen in younger TD children, suggesting that language development is a robust process and does not seem to be differentially affected by ID even when delayed.

“…Difficulties with passives are reported to persist into adolescence in William's Syndrome (Perovic & Wexler 2010), Down's Syndrome (Perovic 2006) and grammatical SLI, where reversible, full verbal passive constructions are problematic (van der Lely 1996;Bishop et al 2000;Norbury et al 2002;Montgomery & Evans 2009, a.o.). Interestingly, these populations also show deficits in verbal working memory (e.g.…”

This study investigates the comprehension of passives in children with Autism Spectrum Disorder (ASD). Subsets of children with ASD have been previously found to present linguistic profiles reminiscent of Specific Language Impairment (SLI), a condition including difficulties with certain constructions displaying noncanonical word orders. However, research on one such construction, passives, is sparse and remains inconclusive. Furthermore, studies on typical development of passives in French are lacking. Twenty French-speaking children with ASD (mean age 9;3), including children with both normal and delayed nonverbal levels, were compared to 20 age-matched typically-developing (TD) children and to 65 younger TD children split into groups of children aged 4-5, 6-7 and 8-9 years. Various passive types were assessed via a sentencepicture matching task: eventive versus psychological, and short versus long. Most children with ASD showed difficulties on passive constructions as compared to age controls, although with the same basic pattern of performance. More subtle delay on passives was evident in a subgroup who was otherwise unimpaired on standardized assessments of vocabulary and morphosyntax, while a pronounced delay on passives was detectable in another subgroup also displaying more general lexical and morphosyntactic impairment. Difficulties with passives were dissociated from nonverbal abilities and working memory. The findings reveal that the syntax of passives is delayed in ASD, not deviant. This delay was attested even in the subgroup with seemingly intact general language skills as revealed by standardized assessments, suggesting that subtle difficulties with this construction may be present and go undetected by global language tests. Performance on passives was unrelated to nonverbal abilities, in line with work suggesting that the linguistic phenotype of some children with ASD resembles SLI. This underscores the importance of careful assessment of the language abilities of children with ASD, including those within normal IQ range.

Autism Spectrum disorders have attracted the attention of many researchers working on communicative and pragmatic competence, but much less attention has been paid to the investigation of narrow syntax in this condition. On the other hand, in the field of acquisition, passive sentences (and related constructions) are known to be a late acquisition, and have been argued to be a case of late maturation. In this paper we report results on the comprehension of passive sentences in Persian-speaking children with typical development and with Autism Spectrum Disorders. In our findings, not all ASD children perform in the same way, rather those considered to be high-functioning perform like the typically developing, and the low-functioning have a clearly poorer performance. These results shed some light on former studies , Terzi et al. 2014, with seemingly inconsistent results due to the fact that heterogeneous populations were tested.Keywords: passives; comprehension; acquisition; Autism Spectrum Disorders; Persian. Resum. Una investigació sobre la comprensió de les passives del persa en casos de desenvolupament típic i d'autismeEls desordres d'espectre autista han interessat molts investigadors de la competència comunicativa i pragmàtica, però no s'ha parat gaire atenció a l'estudi de la sintaxi estricta d'aquesta condició. Per altra banda, en l'àmbit de l'adquisició, s'ha observat que les oracions passives (i construccions relacionades) s'adquireixen tard i s'ha proposat que són un cas de maduració tardana. En aquest * The authors would like to genuinely thank Mr. Zojaji, founder of the Autism Children Charity Foundation, for his support, and all participants for their willingness to take part in our experiment. We have greatly benefited from discussion with Fatemeh Nemati and from the suggestions of an anonymous reviewer. We also wish to thank Anna Espinal and Ester Boixadera (of the Servei d'Estadística Aplicada at the UAB) for the statistical analysis, and projects FFI2011-29440-C03-03 and 2009SGR 1079 for financial support.

CatJL 13, 2014Anna Gavarró; Yalda Heshmati article descrivim els resultats d'un experiment de comprensió de les oracions passives en nens parlants del persa amb desenvolupament típic i amb autisme. Les nostres investigacions mostren que no tots els nens autistes tenen el mateix comportament: mentre que els nens autistes amb elevada funcionalitat obtenen resultats similars als dels nens amb desenvolupament típic, els nens autistes amb funcionalitat baixa tenen uns resultats clarament pitjors. Aquestes dades aporten una nova perspectiva als estudis previs , Terzi et al. 2014, que mostraven resultats aparentment inconsistents a causa de l'heterogeneïtat de les poblacions analitzades.
