Mandarin non-interrogative wh -words distinguish between children with Developmental Language Disorder and language-impaired autistic children
Language profile resemblance between autisticFootnote11 The current paper uses “identity-first” language throughout, which is often favored by autistic individuals and their parents (Kenny et al. Citation2016). children who are language-impaired and children with Developmental Language Disorder (DLD) gives rise to misdiagnosis of the two conditions. Aiming to better understand the underlying causes of language impairments in autism language impai…
Socio-economic status and other potential risk factors for language development in the first year of life
A wide variety of language skills has been shown to be compromised in children from low socioeconomic status (SES). However, few studies have investigated the effect of SES on language development in infants. The aim of this study is two-fold: to investigate when the first SES-effects on language can be observed and to explore the effects of three variables often claimed to be linked to SES – gestational duration, stress and parent-child interact…
Topicality and anaphoricity in Dutch scrambling
Direct objects in Dutch can precede or follow adverbs, a phenomenon commonly referred to as scrambling . The linguistic literature agrees in its assumption that scrambling is regulated by the topicality and anaphoricity status of definite objects, but theories vary as to what kinds of objects exactly are predicted to scramble. This study reports experimental data from a sentence completion experiment with adult native speakers of Dutch, showing t…
The influence of cognitive abilities on article choice and scrambling performance in Dutch-speaking children with autism
This study addresses the question as to what cognitive abilities influence performance on article choice and direct object scrambling in high-functioning Dutch-speaking children with Autism Spectrum Disorder (ASD). Schaeffer (2016/2018) shows that a group of 27 high-functioning Dutch-speaking children with ASD, aged 5–14, overgenerates the indefinite article, and fails to scramble significantly more often than TD age-mates. As article choice, dir…
On links between language development and extralinguistic cognitive knowledge
This Special Issue on linguistic and cognitive development in children with autism spectrum disorder (ASD) arose from the 42nd Boston University Conference on Language Development (BUCLD) (2017), when Jeannette Schaeffer, Stephanie Durrleman, and Inge-Marie Eigsti organized a symposium on this topic. It shows that the study of language development in ASD provides a unique perspective on the associations between the development of syntax, pragmati…
Language-developmental trajectory in autism
present an interesting and much needed scoping review on bilingual language development and autism, putting its finger on several important issues and shortcomings in studies on (monolingual and bilingual) language (development) and autism. In this response to P&T we touch on several topics that have recently inspired discussions in our Languagein-Autism (LiA) lab in Amsterdam, including language-developmental trajectory in relation to data colle…
Definite-indefinite article choice development in Dutch child language
Many acquisition studies indicate that across languages, children overgenerate definite articles in indefinite contexts. However, proportions and ages at which children make this error vary, and so do theoretical accounts. Attempting to resolve some of the mixed results, we combined the methods of two different studies ( Schaeffer & Matthewson 2005 (SM) and van Hout, Harrigan & de Villiers 2010 (HHV)) and administered them to one group of 82 Dutc…
Unravelling the complexity of Direct Object Scrambling
Object relative clauses in Dutch-speaking children with High-Functioning Autism (HFA)
Previous studies show that Direct Object Scrambling (DOS) is impaired in Dutch-speaking children with High-Functioning Autism (HFA). However, as DOS can be considered a syntax-pragmatics interface phenomenon, it is unclear whether DOS errors are due to impaired syntax or impaired pragmatics. In order to shed light on this question, the current study investigates Object Relative Clauses (ORC), assumed to involve syntactic object placement (as in D…

Grammatical and pragmatic properties of the DP in children with Specific Language Impairment (SLI) and in children with High Functioning Autism (HFA)
This study investigates whether grammar and pragmatics are separate linguistic components or not, and whether children with SLI and children with HFA have overlapping or distinct linguistic profiles. We examine two DP-related phenomena: the mass-count distinction (grammatical) and the choice for a definite/indefinite article (pragmatic). We tested 27 children with HFA aged 6–14, age and gender matched to 27 children with SLI, and 27 TD controls o…
Reference and referentiality in native and learner grammars
Article choice in children with High Functioning Autism (HFA) and in children with Specific Language Impairment (SLI)
This study reports on the choice between a definite and an indefinite article by children with High Functioning Autism (HFA) and children with Specific Language Impairment (SLI). We carried out an elicited production task with 16 Dutch-speaking non-grammatically impaired children with HFA aged 6–13, 16 age-matched Dutch-speaking children with SLI, and 16 typically developing (TD) age controls. The results in the indefinite conditions reveal virtu…
Grammar and Pragmatics in the Acquisition of Article Systems
Verbal Syntax and Morphology in Typically Developing Dutch Children and Children With Sli
This paper is a study of normal and impaired (SLI) linguistic development, especially in verbal morphology and syntax. The paper studies both linguistic development and how developmental phenomena provide evidence for adult linguistic theory. We use extensive developmental data to test models of normal and impaired development that have been applied to other languages-in particular, the Agr/Tense Omission Model (ATOM). We develop detailed models …
