Brewer, Young, and Barnett reported a comprehensive psychometric evaluation of a new adult theory of mind measure (A-ToM) with a sample of high-functioning autism spectrum disorder (ASD) adults. Although correlations with existing theory of mind (ToM) instruments (i.e., the Strange Stories; the Frith- Happé animations) were reported, relationships…

Persuasion is an essential social skill. Yet its development and underpinnings are poorly understood. In 2 studies, a total of 167 children aged 3 to 12 years took theory of mind (ToM) tests and participated in unscripted, seminaturalistic persuasive conversations. Children were typically developing (TD) or had deafness or autism spectrum disorder…

To explore this, we developed a novel test involving competition to win a reward as the motive for tracking other players' beliefs (the…

Consequences of theory of mind (ToM) development for daily social lives of children are uncertain. Five to 13-year-olds (N = 195) with typical development, autism, or deafness (both native and late signers) took ToM tests and their teachers reported on their social skills for peer interaction (e.g., leadership, group entry). Groups differed in…
