This study examined the cognitive predictors and constraints of children's strategic offers in the Ultimatum Game. The Ultimatum Game is a one-shot negotiation on the division of a given sum of rewards between two people, where the receiver has the right to punish the proposer by rejecting unfair offers, which results in nil reward for either…

The reliability and validity of the Children's Social Understanding Scale (CSUS) was further assessed by examining fathers' as well as mothers' reports of children's social understanding, along with behavioural measures of children's mental state understanding. 112 families with children aged 38 to 64 months participated with both parents filling…

When and how do children develop an understanding of the subjectivity of intentions? Intentions are subjective mental states in many ways. One way concerns their aspectuality: Whether or not a given behavior constitutes an intentional action depends on how, under which aspect, the agent represents it. Oedipus, for example, intended to marry…

First-order theory of mind (ToM) development has shown to conform to a Guttman scale, with desire reasoning developing before belief reasoning. There have been attempts to test for internal consistency and scalability in advanced ToM, but not over a broad age range and only with a limited set of tasks. This 2-year longitudinal study (N = 155;…

To successfully pull a practical joke on someone, children need to understand that their victims do not know what they themselves know, be able to intentionally manipulate others' beliefs, and maintain a straight face to safeguard the integrity of the joke. This study examined the relationship between children's developing theory of mind (ToM),…

With nearly half of all children under age six living in poverty, it is imperative to explore the development of income-related childhood aggression. Here, we specifically examine how family socioeconomic status (SES) relates to children's physical and relational aggression, and how this relation may be moderated by burgeoning social cognition.…

Perspective taking is a fundamental skill that helps us to understand others' thoughts, feelings and perceptions. Past studies have shown that there were significant relations between young children's perspective taking abilities and age, gender, formal schooling and socioeconomic status. The present study was conducted to investigate the…

Semantic fluency (SF) is a suitable indicator of preschool verbal abilities and can be used as a predictor of later school success. This research examined the effects of executive functions (EF) and theory of mind (TOM) on semantic fluency in preschool children. Dimensional Card Sorting test was used as an instrument of executive functions and the…

To date, cross-cultural studies on Theory of Mind (ToM) have predominantly focused on preschoolers. This study focuses on middle childhood, comparing two samples of mainland Chinese (n = 126) and Australian (n = 83) children aged between 5.5 and 12 years. Strange Stories, the most commonly used measure of ToM, was employed. The study aimed to…

The development of emotion understanding in young Chinese preschoolers was examined. The overall developmental trend, as measured by the Test of Emotion Comprehension (TEC), proved similar to that found among preschoolers in Western Europe. However, Chinese children performed better at understanding the distinction between real and apparent…

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…

Research has documented various family and individual risk factors associated with severe conduct problems, but little is known about the developmental origins of children who engage in both aggressive and prosocial interactions with others. The present study utilized growth-mixture modeling to identify distinct trajectories of physical aggression…

Mothers' mental-state references predict individual differences in preschoolers' false-belief (FB) understanding; less is known about the origins of corresponding variation in school-age children. To address this gap, 105 children completed observations with their mothers at child ages 2 and 6, three FB tasks and a verbal comprehension…

A simple "expression" account of the relation between executive function (EF) and children's developing theory of mind (ToM) has difficulty accounting for the generality of the changes occurring in children's mental-state understanding during the preschool years. The current study of preschool children (N = 43) showed that EF--especially…

We investigated links between persuasive behavior and theory of mind (ToM) understanding using a novel naturalistic peer persuasion task in which children were invited to convince an interactive puppet to eat raw broccoli or brush his teeth. Sixty-three 3- to 8-year-olds (M age = 6 years, 6 months) took part in the persuasion task and were also…
