A Longitudinal Study of the Relations Between Theory of Mind, Executive Function, and Lying in Children.

This study used longitudinal cross-lagged modeling to examine the contribution of theory of mind (ToM), executive function (EF) to children's lying development and of children's lying to ToM and EF development. Ninety-seven Chinese children (initial M age = 46 months, 47 boys) were tested three times approximately 4 months apart. Results showed that the diverse desire understanding and knowledge access understanding components of ToM, as well as the inhibitory control component of EF predicted the development of children's lying, while the diverse belief understanding and false belief understanding components of ToM, and the working memory component of EF did not predict development of children's lying. Meanwhile, children's lying predicted development of children's belief-emotion understanding components of ToM, but not any other ToM components, or EF components. These findings provide longitudinal evidence for the relation between ToM, EF, and children's lying during the preschool years.

Children's reputation management: Learning to identify what is socially valued and acting upon it.

Much of what people do is motivated by a concern with social evaluation. We argue that the process of figuring out what others value and making effective use of this information presents significant cognitive challenges. These challenges include reasoning about the relevance of different forms of information and making inferences about the mental lives of others. They also include modifying one's behavior in light of whatever personal qualities appear to be valued in an effort to appeal to different audiences. We argue that the foundations of many of the important skills needed to meet these challenges are already in place early during childhood, but that the challenges themselves persist well into adulthood.
