Does language have a role to play in conceptual development, and if so, what is that role? Understanding the contents of another person's mind parallels the development in early childhood of mental state language. Does the conceptual understanding get reflected in and drive the language development, or does the language allow the representation of…

We investigated the relations among theory of mind (ToM), mental state talk, and discourse comprehension. Specifically, we examined the frequency of mental state talk in children's oral recall of narrative texts and informational texts as well as relations among ToM, mental state talk (inclusion of mental state words in the recall of narrative and…

Research Findings: Research with older children and adults reliably demonstrates that individuals raised in poverty tend to evaluate concerns related to moral concerns (i.e., related to harm, welfare, and justice) differently than do wealthier individuals. However, little work has examined these patterns in young children. Children (N=214, Mage =…

The ability to represent the mental states of other agents is referred to as Theory of Mind (ToM). A developmental breakthrough in ToM consists of understanding that others can have false beliefs about the world. Recently, infants younger than 2 years of age have been shown to pass novel implicit false belief tasks. However, the processes…

The aim of this study was to test the relationship of theory of mind (ToM) and maternal emotional expressiveness with children's aggressive behaviours (i.e., relational aggression, physical aggression). ToM is vital to relational aggression, which involves harming others through purposeful manipulation and damaging peer relationships. However,…

Adults with autism spectrum disorder (ASD) often experience social marginalisation. This study uses a vignette-based design to clarify whether diagnostic disclosure affects social marginalisation in workplace contexts. It investigates two potential mediators of this relationship: affective response to and theory of mind for people with ASD.…

The acquisition of theory of mind (ToM) -- the ability to attribute mental states to explain others' behaviors -- is a critical milestone in children's cognitive development. Previous research has established that deaf children experience significant delays in ToM compared to hearing children within the same culture. However, prior studies were…

Attention-deficit/hyperactivity disorder is one of the most common comorbidities in individuals with autism spectrum disorder. However, the clinical implications of the co-occurrence of these two disorders are still poorly understood. Based on a preregistered protocol (PROSPERO CRD42020193880), this systematic review identified 34 articles,…

Autistic people have difficulties recalling episodic memories, including retrieving fewer or less specific and detailed memories compared to typically developing people. However, the ability to effectively recall episodic memories is crucial in many real-world contexts, such as the criminal justice system, medical consultations, and employment…

When and how do children develop an understanding of the subjectivity of intentions? Intentions are subjective mental states in many ways. One way concerns their aspectuality: Whether or not a given behavior constitutes an intentional action depends on how, under which aspect, the agent represents it. Oedipus, for example, intended to marry…

Sociodramatic play is considered a critical context within which child leaders and followers may naturally emerge, while their cognitive abilities (e.g., theory of mind) and social competence are developed and applied. This study investigated child leadership and followership during sociodramatic play among 20 racial/ethnic minority 3- and…

Autistic people are often described as being impaired with regard to theory of mind, though more recent literature finds flaws in the theory of mind deficit paradigm. In addition, the predominant methods for examining theory of mind often rely on "observational" modes of assessment and do not adequately reflect the dynamic process of…

Purpose: When breakdowns in communication occur, children may request a repair to increase understanding of the message. Unrepaired communication breakdowns may cause confusions, limit conversational exchanges, and restrict children's learning opportunities. Relatively little is known regarding the conditions under which children produce repair…

The present study examined the role of executive function in lying for children with autism spectrum disorder (ASD). The temptation resistance paradigm was used to elicit children's self-protective lies and the Hide-and-seek task was used to elicit children's self-benefiting lies. Results showed that children with ASD told fewer lies in the two…

Research that focused on Theory of Mind (ToM) development in blind children showed that they were delayed, but not permanently deficient, in various types of false belief tasks. More recent studies reported first evidence of typical ToM development in blind children and suggested that more comprehensive tools to evaluate ToM had to be used. The…
