The objective of this study was to examine the relation between personality traits and prosocial lie-telling in children. A sample of 187 children aged 8-12 years (M[subscript age] = 9.74 years, SD[subscript age] = 1.01) was recruited from elementary schools in the south of France. The children's prosocial lies were measured using the Helping…

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;…

The present investigation examined the relation between honesty, benevolence, and trust in children. One hundred and eight 7-, 9-, and 11-year-olds were read four story types in which the character's honesty (honesty or dishonest) was crossed with their intentions (helping or harming). Children rated the story character's honesty, benevolence, and…

In this study we looked at how 3- and 5-year-old refugee…

Do interventions work and for whom? For this article, we examined the influence of population heterogeneity on power in designing and evaluating interventions. On the basis of Monte Carlo simulations in Study 1, we demonstrated that the power to detect the overall intervention effect is lower for a mixture of two subpopulations than for a…

This study examined developmental differences in, and cognitive bases of, coping flexibility in children with and without ADHD. Younger (age 7 to 8) and older (age 10 to 11) children with and without ADHD (N = 80) responded to hypothetical vignettes about problematic interactions with peers that shifted from controllable to uncontrollable over…

Using a puppet procedure depicting hypothetical conflict involving the participant and a peer, 96 preschoolers' (48 boys and 48 girls; M = 5.14 years, SD = 0.78 years) expectations about peer conflict were assessed as a function of their role in the conflict (i.e., initiator of or responder to initial provocation) and the intensity level of the…
