Understanding nonliteral language requires inferencing ability and is an important but complex aspect of social interaction, involving cognitive (e.g., theory of mind, executive function) as well as language skill, areas in which many deaf individuals struggle. This study examined comprehension of metaphor and sarcasm, assessing the contributions…

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…

We investigated "scalar implicature" in adolescents and children with autism spectrum disorder (ASD) to test whether theory of mind deficits associated with autism affect pragmatic inferences in language. We tested scalar implicature computation in adolescents with ASD (12-18 years) and asked whether they reason about mental states when…

The goal of the current study was to statistically evaluate the reliable scalability of a set of tasks designed to assess Theory of Mind (ToM) without language as a confounding variable. This tool might be useful to study ToM in populations where language is impaired or to study links between language and ToM. Low verbal versions of the ToM tasks…

Children vary in their ability to use language in social contexts and this has important consequences for wellbeing. We review studies that test whether individual differences in pragmatic skill are associated with formal language ability, mentalizing, and executive functions in both typical and atypical development. The strongest and most…

This longitudinal study examined pragmatic language in boys and girls with Down syndrome (DS) at up to three time points, using parent report, standardized and direct assessments. We also explored relationships among theory of mind, executive function, nonverbal mental age, receptive and expressive vocabulary, grammatical complexity, and pragmatic…

In recent decades, a growing number of children have been diagnosed with autism spectrum disorder (ASD), a condition characterized by social interaction deficits and language impairment. Yet the precise nature of the disorder's impact on language development is not well understood, in part because of the language variability among children across…

It has been argued that children who possess an advanced theory of mind (ToM) are more likely to act prosocially, yet the empirical findings are mixed. To address this issue definitively, a meta-analytic integration of all prior literature that met appropriate inclusion criteria was conducted. In total, 76 studies including 6,432 children between…

Children's use of internal-state language during 2 tasks (book narration and describing a best friend) was investigated in a sample (N=38) of 7- to 9-year-olds. Proportional use of internal-state talk on the two tasks was highly positively correlated, a relation that was independent of verbosity, age, verbal ability and the use of…

This article presents three studies conducted in Canada and Australia that relate theory of mind (ToM) development to mental state discourse. In Study 1, mental state discourse was examined while parents and their 5-7-year-old children jointly read a storybook which had a surprise ending about the identity of the main character. Comments specific…
