We examine the long-standing claim that understanding relational correspondence is a general component of representational understanding. Two experiments with 175 preschool children located in Norwich, United Kingdom, examined the use of a scale model comparing performances on a "copy" task, measuring abstract spatial arrangement…

Scientific literature indicates that theory of mind (ToM) is less strongly associated with peer acceptance (PA) in the case of boys and the case of negative nominations. This study hypothesizes that these two effects of ToM on PA could be an epiphenomenon of counterfactual reasoning (CFR). Fifty-three 3-5-year-olds participated in this study. The…

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…

Understanding emotions based on false beliefs is a necessary component of theory of mind. Previous research has indicated a lag in children's understanding of belief-based emotions as compared to false beliefs. Experiment 1 involved 83 Chinese 3- to 5-year-old children who were tested for the developmental change of the belief-emotion lag.…

The metarepresentational aspect of early pretend play (make-believe activities where children create or participate in creating a new situation different from a real one) has been theoretically debated. In the present longitudinal study of N = 83 children, we tested for predictive relations of shared attention at 12-18 months, implicit false…

Theory of mind skills are critical to understanding and interpreting many illustrations in primary school literature especially those which are used in material for the purpose of learning to read. Unfortunately, children who learn to read at an early age as well as mainstreamed children, such as those with autism, often have grave deficiencies in…

In a longitudinal study (N = 54), we investigated the developmental relation between children's implicit and explicit theory of mind and executive functions. We found that implicit false belief understanding at 18 months was correlated with explicit false belief understanding at 4 to 5 years of age, with the latter being closely related to…

Oral retelling portrays what one understands from reading or listening to a text. The retold stories of children with autism spectrum disorder (ASD) often show macrostructural (overall story structure) difficulties. The study's purpose was to compare macrostructure oral story retelling, after reading (visual modality) or listening (auditory…

It has been argued that the distinction between factivity and non-factivity is more fundamental to mental state understanding than that between false beliefs and reality. The present study examined children's growing understanding of all possible contrasts between the factive verb "know" and the non-factive verbs "think" and…

Identifying correlates of aggressive behavior in children might help to find potential candidates for interventions in aggression reduction. While some previous studies found that children's Theory of Mind (ToM) and inhibitory control (IC) correlate with aggressive behavior, others did not confirm this relation. One explanation for these mixed…

This study examined children's understanding of irony when a difference existed between a speaker's intended meaning and a listener's interpretation of the meaning. Three irony contexts were presented to 87 7/8-year-olds (second graders), 90 11/12-year-olds (sixth graders), and 103 adults. In the normal irony context, the speaker intended to…

We told ninety-nine 4- and 5-year-olds stories in which speakers told lies and truths in two contexts: those told to deny a transgression (misdeeds) and those told to spare another's feelings (politeness). Participants identified each statement as a lie or as the truth, morally judged it as good or bad, and decided whether or not to assign…

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),…

It has been debated whether the progressive emergence of theory of mind (ToM) in autistic children is compatible with a "delayed" or "different" development model, and whether and how the sequential consolidation of ToM concepts is subject to cross-cultural variations in autistic and typically developing (TD) children. To study…
