Purpose: Relative clauses present a well-known processing asymmetry between object-extracted and subject-extracted dependencies across both typical and atypical populations. The present study aimed at exploring the comprehension of object and subject relative clauses as conceptualized by the Relativized Minimality framework in autistic children…

Determining how and why adult outcomes of heritage speaker (HS) bilingualism differ from monolinguals is difficult because it requires the reconstruction of developmental paths from end-state data. In an effort to address this issue, we examine HSs of Turkish in Germany at an early age of development (10-15 years old, n = 22), as well as…

Background: A limited number of studies have analyzed grammaticality in monolingual Spanish-speaking children with specific language impairment (SLI). Most of the available data are based on bilingual speakers. Aims: To extend previous studies by doing a more detailed analysis of grammatical types in monolingual Spanish-speakers with and without…

The present study investigated the comparison between short and long-term effectiveness of input-providing and output-prompting negotiation strategies on mastering the target structures. To this end, the participants were divided into three groups, namely two experimental groups who had a special kind of treatment, and one control group without…

Children with specific language impairment (SLI) perform poorly on sentence repetition tasks across different spoken languages, but until now, this methodology has not been investigated in children who have SLI in a signed language. Users of a natural sign language encode different sentence meanings through their choice of signs and by altering…

This study investigates the question as to whether and how the linguistic and other cognitive abilities of children with Specific Language Impairment (SLI) differ from those of children with High-Functioning Autism (HFA). To this end, 27 Dutch-speaking elementary-school-age children with SLI, 27 age-matched children with HFA, and a control group…

Children with Autism Spectrum Disorder (ASD) aged 11-13 (N = 16) and an IQ-matched typically developing (TD) group aged 7-12 (N = 16) completed a graded grammaticality judgment task, as well as a standardized test of cognitive function. In a departure from previous studies, the judgment task involved verb argument structure overgeneralization…

Purpose: The authors explored the cognitive mechanisms involved in language processing by systematically examining the performance of children with deficits in the domains of working memory and language. Method: From a database of 370 school-age children who had completed a grammaticality judgment task, groups were identified with a co-occurring…

Morphosyntax constitutes one of the most complex areas of language. It takes into account the structure of the word and that of the sentence, and its development allows one to establish adequately agreements both within the nominal phrase and in the rest of the sentence. Morphosyntax is particularly impaired in individuals with Down syndrome. To…

This study investigates whether distinct neurodevelopmental disorders show distinct patterns of impairments in particular grammatical abilities and the relation of those grammatical patterns to general language delays and intellectual disabilities. We studied two disorders (autism and Williams syndrome [WS]) and two distinct properties (Principle…

The present study examines and compares the extent to which advanced L2 learners of Spanish and Spanish heritage speakers acquire the syntactic and semantic properties that regulate the grammatical representation of double complementizer questions in Spanish, a CP-related structure not present in English. Results from an aural sentence completion…

Although pragmatic deficits are well documented in autism, little is known about the extent to which grammatical knowledge in this disorder is deficient, or merely delayed when compared to that of typically developing children functioning at similar linguistic or cognitive levels. This study examines the knowledge of constraints on the…

Grammatical gender is generally considered an early and error-free acquisition in French children. This article first examines how children cope with the gender attribution problem, "i.e.", how they determine the gender of individual nouns. We consider the plausibility and requirements of an account in which tacit phonological assignment rules are…

The authors investigated past-tense morphology problems in children with dyslexia compared to those classically observed in children with oral language impairment (LI). Children were tested on a past-tense elicitation task involving regulars ("look-looked"), irregulars ("take-took"), and nonwords ("murn-murned").…

Purpose: The authors studied the effect of the cochlear implant (CI) on language comprehension and production in deaf children who had received a CI in the 2nd year of life. Method: The authors evaluated lexical and morphosyntactic skills in comprehension and production in 17 Italian children who are deaf (M = 54 months of age) with a CI and in 2…
