The alexithymia hypothesis posits that specific aspects of the autistic socio-cognitive profile, namely emotion recognition difficulties, can be explained by the increased prevalence of alexithymia in autistic populations. However, this hypothesis has largely been tested in adults. We tested whether co-occurring alexithymia could account for…

This study described the development of a culturally adapted video version of Strange Stories test as a measure of advanced theory of mind for youths in an Asian country (i.e. Singapore), the Y-ToM, and to provide preliminary psychometric properties. Participants were 170 youths (82 male, 88 female) aged from 13 to 16 years old (M = 14.77, SD =…

The aim of the current study was to examine theory of mind (ToM), the ability to infer the mental states of others, in young adults who are deaf and hard-of-hearing (DHH), and to explore the influence of alexithymia, an inability to understand emotions of the self and others, on ToM performance in this group. Compared to participants with typical…

Understanding emotions based on false beliefs is a necessary component of theory of mind. Previous research has indicated a lag in children's understanding of belief-based emotions as compared to false beliefs. Experiment 1 involved 83 Chinese 3- to 5-year-old children who were tested for the developmental change of the belief-emotion lag.…

This paper, conceptual but with empirical support, fills in some blanks in Vygotsky's reworking of Spinoza's "Ethics." Here Vygotsky sought to develop a developmental theory of emotions that would fit his developmental theory of higher psychological functions; that is, one which used function to explain how structure changes (much as…

Learning to write is a complex process involving linguistic, cognitive, and socio-emotional factors. From a developmental perspective, little research has explored the content of young children's writings in terms of specific cognitive skills such as Theory of Mind (TOM). This study explores how young children's writing may foster representations…

This study examined the relationship between mental state term use in children with autism spectrum disorder (ASD) and typically developing (TD) children engaged in play. Expression of mental state terms was used as an indicator of theory of mind (ToM) skills. Archived data were used to compare mental state term use for five ASD-TD dyads engaged…

Investigated between-group differences in cognitive/affective theory of mind (ToM) and predictors of cognitive ToM both within broad autism phenotype/non (BAP/Non-BAP) groups as well as across the sample. The BAP group (n = 45) performed worse than the Non-BAP group (n = 102) on the unexpected outcomes test (UOT), but groups were similar regarding…

The current study examined relations between distinct aspects of moral functioning, and their cognitive and emotional correlates, in preschool age children. Participants were 171 typically developing 3- to 6-year-olds. Each child completed several tasks, including (a) moral tasks assessing both performance of various moral actions and evaluations…

Text social information includes the cognitive processes and social communication skills that support real or hypothetical human thought or interaction. The current measure of text social information is genre. However, genre is a limited measure because of poor operationalization, limited specificity, and overlap with structural and linguistic…

The extent to which Theory of Mind (ToM) performance is influenced by cultural and gender differences remains a subject of debate. A sample of 324 Dutch and 511 Italian children (52% boys; 2.8-11.7 years; 50% boys; 2.6-10.3 years; respectively) was administered the ToM Storybooks. Analysis focused on indicators of nonlinearity: moving standard…

The social symptoms of autism spectrum disorder are likely influenced by multiple psychological processes, yet most previous studies have focused on a single social domain. In school-aged autistic children (n = 49), we compared the amount of variance in social symptoms uniquely explained by theory of mind (ToM), biological motion perception,…

Emotion comprehension (EC), theory of mind (ToM), and language are particularly important aspects of child development. In recent years, there has been increasing interest in understanding how these three variables are related to preschool children. However, results have been contradictory, and it is not clear how EC, ToM, and language are…

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.…
