Longitudinal tracking of 107 three- to-thirteen-year-olds in a cross-sequential design showed a 6-step theory of mind (ToM) sequence identified by a few past cross-sectional studies validly depicted longitudinal ToM development from early to middle childhood for typically developing (TD) children and those with ToM delays owing to deafness or…

The study used an eye-tracking task to investigate whether preschool children with autism spectrum disorder (ASD) are able to make inferences about others' behavior in terms of their mental states in a social setting. Fifty typically developing (TD) 4- and 5-year-olds and 22 5-year-olds with ASD participated in the study, where their eye-movements…

This study examined the natural social interest of 193 (95 boys, 98 girls) typically developing preschoolers aged 41 to 77 months (M = 61.71 months, SD = 8.48 months) toward their included peers with autism spectrum disorder (ASD; N = 16, M = 66.8, SD = 8.80). A hierarchical linear model examined the role of endogenous (within-child) and exogenous…

Autobiographical memory (AM) is a socially-relevant cognitive skill. Little is known regarding AM during early childhood in ASD. Parent-child reminiscing conversations predict AM in non-ASD populations but have rarely been examined in autism. To address this gap, 17 preschool-aged children (ages 4-6 years) with ASD and 21 children without ASD…

We compared the effectiveness of two programs for developing social skills, 'Play Time/Social Time' (PT/ST) and 'I Can Problem Solve' (ICPS), in improving the social skills and theory of mind (ToM) of preschoolers with ASD. The experiment took place in a classroom setting. Fifty-two children attended and data were analyzed with latent growth curve…

This study examined the Theory of Mind (ToM) abilities of typically developing preschoolers in three age groups: three- to four-, four- to five- and five- to six-years-old (n = 110), who differed in their spontaneous social interest toward included children with autism spectrum disorder (ASD). Social interest was assessed by administering a…

The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged…

The social cognitive deficiencies of children diagnosed with autism spectrum disorders (ASDs) are well documented. However, the mechanisms underlying these deficiencies are unclear. Therefore, we examined the social information processing (SIP) patterns and social behaviors of 25 preschool children with ASDs in comparison to a matched group of 25…

Children with autism spectrum disorder (ASD) have difficulties in theory of mind (ToM) and executive function (EF), which may be linked because one domain (EF) affects the other (ToM). Group differences (ASD vs. typical development) were examined in both cognitive domains, as well as EF's associations and regressions with ToM. Participants…

The discovery that 3-year-old children have difficulties understanding false belief has fuelled two decades of research directed at understanding why children have this problem. One unresolved question is whether false belief problems are due to difficulties with mental or representational aspects of mental states. This question has implications…

Background: In the context of the established finding that theory-of-mind (ToM) growth is seriously delayed in late-signing deaf children, and some evidence of equivalent delays in those learning speech with conventional hearing aids, this study's novel contribution was to explore ToM development in deaf children with cochlear implants. Implants…

Background: Frith and Happe (1994) describe central coherence (CC) as the normal tendency to integrate individual elements into a coherent whole, a cognitive style which varies in the general population. Individuals with autism are at the extreme (weak) end of the continuum of coherence. There has been debate over whether CC is independent from…
