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…

Representational theory of mind--the ability to represent others' mental states and understand that these beliefs can be different from one's own and reality--emerges in early childhood alongside other meta-representational abilities, such as understanding that an image can be perceived in multiple ways. Limited research has suggested that…

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),…

It is well established that children lie in different social contexts for various purposes from the age of 2 years. Surprisingly, little is known about whether very young children will spontaneously lie for personal gain, how self-benefiting lies emerge, and what cognitive factors affect the emergence of self-benefiting lies. To bridge this gap in…

Self-regulation and social cognition flourish as children begin school and engage with a new social environment. At the same time, this novel setting provides more complex social situations that children must navigate, including understanding when others may be lying to them. Social cognition and self regulatory abilities, such as Theory of Mind…

Theory of mind describes the ability to engage in perspective-taking, infer mental states, and predict intentions, behavior, and actions in others. Theory of mind performance is associated with foundational cognitive and socioemotional skills, including verbal ability (receptive and expressive vocabulary), executive function (inhibitory control…

Previous research indicates that children hold negative beliefs about peers with foreign accents, physical disabilities, and people who are obese. The current study examined skills associated with individual differences in children's social judgements about these typically stereotyped groups. Theory of mind, memory, and cognitive inhibition were…

This study examined the interrelationships among second-order belief, interpretive theory of mind, inhibitory control, and the understanding of strategic versus white lies in 54 children approximately 5 years 7 months old. Results showed that second-order belief was associated with strategic-lie understanding, whereas interpretive theory of mind…

Ambiguous figures have fascinated researchers for almost 200 years. The physical properties of these figures remain constant, yet two distinct interpretations are possible; these reverse (switch) from one percept to the other. The consensus is that reversal requires complex interaction of perceptual bottom-up and cognitive top-down elements. The…

Young children's ability to tell a strategic lie by making it consistent with the physical evidence of their transgression was investigated along with the sociocognitive correlates of such lie-telling behaviors. In Experiment 1, 247 Chinese children between 3 and 5 years of age (126 boys) were left alone in a room and asked not to lift a cup to…

Four- to 9-year-olds and adults (N = 256) viewed a series of pictures that were covered with occluders to reveal nondescript or identifiable parts. Participants predicted how 3 characters, 1 who had previously viewed the full picture and 2 who had not, would interpret the obstructed drawings. Results showed significant development between 4 and 9…
