Background: The relationship between language and theory of mind (ToM) development in participants with specific language impairment (SLI) it is far from clear due to there were differences in study design and methodologies of previous studies. Aims: This research consisted of an in-depth investigation of ToM delay in children with SLI during the…

In recent decades, a growing number of children have been diagnosed with autism spectrum disorder (ASD), a condition characterized by social interaction deficits and language impairment. Yet the precise nature of the disorder's impact on language development is not well understood, in part because of the language variability among children across…

Background: Social perception skills, such as understanding the mind and emotions of others, affect children's communication abilities in real-life situations. In addition to autism spectrum disorder (ASD), there is increasing knowledge that children with specific language impairment (SLI) also demonstrate difficulties in their social…

Age-related changes in social attribution skills were assessed using the "Triangles Playing Tricks" task in 7-17 year old high functioning children with ASDs (n = 41) and in typically developing (TD) children (n = 58) matched on age, IQ, and sex ratio. Children with ASDs gave responses that received lower intentionality and appropriateness ratings…

Holding content explicitly requires a form of self-knowledge. But what does the relevant self-knowledge look like? Using theory of mind as an example, this paper argues that the correct answer to this question will have to take into account the crucial role of language-based deliberation but warns against the standard assumption that explicitness…

This study investigates syntax in Autism Spectrum Disorders (ASD), its parallelism with Specific Language Impairment (SLI) and its relation to other aspects of cognition. We focus on (1) 3rd person accusative clitic (ACC3) production, a clinical marker of SLI hypothesized to relate to WM, and (2) 1st person accusative clitic (ACC1) production,…

Theory of mind (ToM) development, assessed via "litmus" false belief tests, is severely delayed in autism, but the standard testing procedure may underestimate these children's genuine understanding. To explore this, we developed a novel test involving competition to win a reward as the motive for tracking other players' beliefs (the…

Introduction: Delays in theory of mind (ToM) of children who are congenitally blind have often been attributed to the absence of visual and social experiences. However, these delays could also be partly due to neural factors. In some children, the blindness itself has neural causes (ocular-plus blindness). Children whose blindness has an…

The present study examines the efficacy of a social skills and Theory of Mind (S.S.ToM) intervention for children with high-functioning ASD. Children were taught to identify and consider their peer's mental states, e.g., knowledge, emotions, desires, beliefs, intentions, likes and dislikes, while learning friendship-making skills and strategies,…

Recent advancements in the field of infant false-belief reasoning have brought into question whether performance on implicit and explicit measures of false belief is driven by the same level of representational understanding. The success of infants on implicit measures has also raised doubt over the role that language development plays in the…

Children with autism spectrum disorders (ASDs) routinely fail false belief tests of theory of mind (ToM), even at advanced chronological and mental ages. Initial training efforts were largely disappointing for those with ASD, suggesting an intractable deficit. However, more recently, children with ASD trained with various pictorial strategies…

The present study examined whether full access to sign language as a medium for instruction could influence performance in Theory of Mind (ToM) tasks. Three groups of Italian participants (age range: 6-14 years) participated in the study: Two groups of deaf signing children and one group of hearing-speaking children. The two groups of deaf…

Background: Translating research findings into practice should be one of the objectives of developmental psychology. Recently, research demonstrated the existence of individual differences in theory of mind (ToM) during middle childhood that are crucial for children's academic and social adjustment. Aims: This study aims to transfer the results of…

The processes and mechanisms of theory-of-mind development were examined via a training study of false-belief conceptions in deaf children of hearing parents (N = 43). In comparison to 2 different control conditions, training based on thought-bubble instruction about beliefs was linked with improved false-belief understanding as well as progress…

In a series of 4 experiments, we tested children's understanding that the causes of their actions must necessarily be attributed to information known prior to (i.e., "pre-action" information), rather than after (i.e., "post-action" information), the completion of their actions. For example, children were shown a dog, asked…
