Developmental science has experienced a vivid debate on whether young children prioritize goals over means in their prediction of others' actions. Influential developmental theories highlight the role of goal objects for action understanding. Yet, recent infant studies report evidence for the opposite. The empirical evidence is therefore…

A large sample of autistic and non-autistic adults was recruited to investigate whether self-reported beliefs about their own and other people's mindreading abilities were in line with either mindreading deficit accounts of autism or the double empathy problem (DEP) (which proposes mindreading difficulties are relational in autism). Three hundred…

Background: Previous literature suggests that children with Down syndrome (DS) have difficulties in cognitive and affective components of Theory of Mind (ToM). However, the nature of the distinction between cognitive and affective ToM has not yet been addressed in depth in this population. Aims: This work is aimed at studying the cognitive and…

While there is considerable evidence that children's early ability to understand others' mental states, called "theory of mind," is shaped by family experiences, it remains unclear whether children's social interactions at school influence theory of mind (ToM) beyond early childhood. We tested whether the mean level…

The emergence of moral emotions such as guilt is central in moral and prosocial development. Guilt is an important psychological factor, which motivates prosocial behaviour and is credited for multiple social functions. Importantly, it remains unclear what determines the extent to which children show guilt. The current study examined two factors…

Superstitious behaviors persist across time, culture, and age. Although often considered irrational and even potentially harmful, superstitions have recently been shown to have positive effects on stress levels, confidence, and ultimately, performance. However, it remains unclear how people conceive of superstitious behaviors, specifically,…

In many cultural contexts, judging another as conscious or not has profound practical, legal, and philosophical consequences. However, little research focuses on how our ability to make such judgements arises. Thirty years ago a classic set of studies by Flavell et al. demonstrated that children do not develop a complex understanding of conscious…

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)…

Previous findings on the association between theory of mind (ToM) and aggression in children are mixed. The "social skills deficit view" regarded ToM as a "single-edged sword" and proposed that a lack of ToM can lead to aggression, while the "double-edged sword view" proposed that children with advanced ToM can still…

Does knowledge of other people's minds grow from concrete experience to abstract concepts? Cognitive scientists have hypothesized that infants' first-person experience, acting on their own goals, leads them to understand others' actions and goals. Indeed, classic developmental research suggests that before infants reach for objects, they do not…

Executive functions' (EF) role in adolescents' advanced theory of mind (aToM) was examined. In Study 1, adolescents (N = 189 in 2017, M[subscript age] = 13.1 years, 55.6% female from racially/ethnically diverse schools) completed the Flexibility and Automaticity of Social Cognition task (FASC), and shifting and inhibition measures. Study 2…

The current study investigated the link between social competence with peers (SCWP) and theory of mind (ToM) skills among Chinese preschool children. Using a sample of 363 Chinese children aged 3-5 (Mage = 4.54 years, SD = 0.84, 183 boys), this cross-sectional study demonstrates that children's SCWP, as reported by teachers, was significantly…

Autistic children and adolescents often have greater difficulty engaging in deception than their non-autistic peers. However, deception in autistic adulthood has received little attention to date. This study examined whether autistic and non-autistic adults differed in their inclination to lie in everyday situations and the factors that underpin…

We investigated the relationship between Theory of Mind (ToM) and communicative cooperation. Specifically, we examined whether communicative cooperation is affected by the ToM ability of one's cooperative partner as well as their own. ToM is the attribution of mental states to oneself and others; cooperation is the joint action that leads to…

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…
