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…

Facilitative linguistic input directly connected to children's interest and focus of attention has become a recommended component of interventions for young children with autism spectrum disorder (ASD). This longitudinal correlational study used two assessment time points and examined the association between parental undemanding…

Children aged 3-2 years (n = 184) with typical development, deafness, autism, or Asperger syndrome took a series of theory-of-mind (ToM) tasks to confirm and extend previous developmental scaling evidence. A new sarcasm task, in the format of H. M. Wellman and D. Liu's (2004) 5-step ToM Scale, added a statistically reliable 6th step to the scale…

Language ability is a known predictor of outcome in children with autism but plays a more controversial role for higher functioning children with autism spectrum disorders (ASD). We studied the relationship between early language milestones and later structural language, adaptive functioning and autism symptoms in a sample of 76 children (mean age…

Background: Developmental disorders of language and communication present considerable diagnostic challenges due to overlapping of symptomatology and uncertain aetiology. We aimed to further elucidate the behavioural and linguistic profile associated with impairments of social communication occurring outside of an autism diagnosis. Methods: Six to…

The primary aim of this paper was to investigate heterogeneity in language abilities of children with a confirmed diagnosis of an ASD (N = 20) and children with typical development (TD; N = 15). Group comparisons revealed no differences between ASD and TD participants on standard clinical assessments of language ability, reading ability or…

Background: Children with specific language impairment (CwSLI) are consistently reported to have short-term memory (STM) and working memory (WM) difficulties. Aim: To compare STM and WM abilities in CwSLI with children with pragmatic language impairment (CwPLI). Methods & Procedures: Primary school-aged CwSLI (n = 12) and CwPLI (n = 23) were…

The presence or absence of clinically delayed language development prior to 3 years of age is a key, but contentious, clinical feature distinguishing autism from Asperger's disorder. The aim of this study was to examine language processing in children with high-functioning autism (HFA) and Asperger's disorder (AD) using a task which taps lexical…

Purpose: How do children with autism spectrum disorders (ASD) extend a noun to the category of objects it labels? Given their tendency to perceive locally, their extensions might be too narrow. Given their social-communicative deficits and a context in which the knowledge of a social-communicative partner promotes narrow extensions, their…

Background: Children who show disproportionate difficulty with the pragmatic as compared with the structural aspects of language are described as having pragmatic language impairment (PLI) or social communication disorder (SCD). Some children who have PLI also show mild social impairments associated with high-functioning autism or autism spectrum…

Children with autism have delays in the development of theory of mind. However, the sub-group of children with autism who have little or no language have gone untested since false belief tests (FB) typically involve language. FB understanding has been reported to be intact in children with specific language impairment (SLI). This raises the…

Background: The few studies that have tracked children with developmental language disorder to adulthood have found that these individuals experience considerable difficulties with psychosocial adjustment (for example, academic, vocational and social aptitude). Evidence that some children also develop autistic symptomatology over time has raised…

Background: Impairments in language and communication are core features of autism spectrum disorders (ASDs). The basis for this association is poorly understood. How early language is related to each of the triad of impairments characteristic of ASDs is also in need of clarification. Aims: This is the first study that aims to determine the extent…

Happe (1993) proposed that theory of mind (ToM) understanding was necessary for comprehension of metaphorical expressions. The current study investigated the role of both ToM and language ability in metaphor understanding. Ninety-four children aged 8-15 years with communication impairments were grouped according to language ability and autistic…
