Give and take: A microgenetic study of preschoolers' deceptive and prosocial behavior in relation to their socio-cognitive development.

Early on, young children begin to learn the social skills which will help them navigate through an increasingly complex social world. We explored how deceiving for personal gain potentially interacts with sharing the resulting resources and how they both relate to theory of mind (ToM) and inhibitory control in 3- to 5-year-old children (N = 92, 43 girls). Children played a hide-and-seek zero-sum game in which they could win stickers if they discovered how to deceive the experimenter.
