This study examined whether school-aged autistic children without co-occurring intellectual disabilities (autisticWoID) show similar difficulty on Theory of Mind (ToM) tasks as young autisticWoID children and if these difficulties are related to problems in domain-general aspects of cognition. Eighty-one autisticWoID and 44 neurotypical (NT)…

The Theory of Mind Inventory-2 (ToMI-2) is a promising measure for assessing theory of mind (ToM) and social-related functions. However, limited evidence on its factorial validity hampers score interpretation. To examine the factorial validity, confirmatory factor analysis for two currently-available structures was performed in 420 typically…

The present study aimed to examine whether Mandarin-speaking children on the autism spectrum showed differences in comprehending spatial demonstratives ("this" and "that", and "here" and "there"), as compared to typically developing (TD) children. Another aim of this study was to investigate the roles of…

Some studies report delayed theory of mind (ToM) development in children with specific language impairment (SLI), while others do not. A ToM delay is acknowledged in children with autism spectrum disorder (ASD), while whether these children also display a deficit is still under debate. In the current study, we drew on a developmental trajectory…

We report an event-related brain potential (ERP) experiment that tests whether autistic adults are able to maintain and switch between counterfactual and factual worlds. Participants (N = 48) read scenarios that set up a factual or counterfactual scenario, then either maintained the counterfactual world or switched back to the factual world. When…

The present study examined the role of IQ and the Theory of Mind understanding in children with an autism spectrum disorder and down syndrome. Sixty-six Swedish children with ASD (n = 26), DS (n = 18), and typically developed group (n = 22) ranged between 6 and 12 years old were compared on ToM tasks consisted of standard ToM and IQ tasks. SPSS 25…

An explanation for the social dysfunction observed in Williams syndrome may be deficits in social cognition. This study explored aspects of social cognition in children with Williams syndrome with different genotypes. The 12 participants included one with a 1.1 Mb deletion that retained the GTF2IRD1, GTF2I, and GTF2IRD2 genes, seven with a 1.5 Mb…

Theory of mind is defined as the understanding that mental states predict and explain people's behaviors. It develops around the age of 4 but seems to remain deficient in people with ASD, whereas other forms of naïve understanding remain intact. This study compares children with ASD to neurotypical children on tasks measuring naïve psychology,…

Theories about autism spectrum disorder (ASD) have addressed cognitive deficits however few have examined how comorbid diagnoses, including sleep disturbance, anxiety and depression contribute to the underlying deficits. We investigated potential mediations of common ASD comorbidities in the relationship between sub-clinical autism traits and…

Several studies suggest that a valuable tool to examine linguistic skills in communication disorders is offered by procedures of narrative discourse assessment. Following this line of research, we present an exploratory study aimed to investigate storytelling abilities of autistic children to better define the characteristics of their story…

The differential diagnosis between schizophrenia spectrum disorders (SSD) and autism spectrum disorders (ASD) remains an important clinical question, because they have overlap in clinical diagnosis. This study explored the differences between ASD (n = 44) and SSD patients (n = 59), compared to typically developing peers (n = 63), in completing an…

This two-year follow-up study examined the predictive relationships of theory of mind (ToM) to social interaction by reciprocal social behaviors (RSBs) and social functioning (SF) in 106 children with ASD. The results of the path analysis showed that the earlier ToM predicted children's current component RSBs (B = 3.53, SE = 1.86, p = 0.039) and…

This study examines relationships between mathematical problem-solving performance (in terms of strategies used and accuracy) and the main cognitive domains associated with mathematical learning (i.e. executive functions, verbal comprehension and social perception) of children with and without autism spectrum disorder (ASD and non-ASD resp.). The…

According to current accounts of social cognition, the emergence of verbal and non-verbal components of social perception might rely on the acquisition of different cognitive abilities. These components might be differently sensitive to the pattern of neuropsychological impairments in congenital neurodevelopmental disorders. Here, we explored the…

Social impairment in Autism Spectrum Disorder (ASD) has been linked to Theory of Mind (ToM) deficits. However, little research has investigated the relationship between ToM and moral decision-making in children with ASD. This study compared moral decision-making and ToM between aggregate-matched ASD and neurotypical boys (n = 38 per group; aged…
