Theorists have speculated about the symbolic underpinnings of theory of mind (ToM), but no study has examined them across the main developmental span of ToM. Here, the onset of symbolic understandings in three domains (pretend play, language, and understanding representations) and ToM was examined. Fifty-eight children were tested on batteries of…

Head Start enhances school readiness during preschool, but effects diminish after children transition into kindergarten. Designed to promote sustained gains, the Research-based Developmentally Informed (REDI) Parent program (REDI-P) provided home visits before and after the kindergarten transition, giving parents evidence-based learning games,…

In line with theories that children's pretend play reflects and extends their narrative skills, children with imaginary companions were predicted to have better narrative skills than children without imaginary companions. Forty-eight 5 1/2-year-old children and their mothers participated in interviews about children's imaginary companions.…

Investigates whether pretend play is an area of advanced understanding with reference to certain skills that are implicated in both pretend play and a theory of mind, including the ability to (1) represent one object as two things at once; (2) see one object as representing another; and (3) represent mental representations.

Three experiments examined 24- though 39-month-olds' understanding of pretend episodes, such as a puppet pouring pretend milk into a container and then tipping it over a toy animal. The children understood the linkage between the two actions and realized that the toy animal would become "wet." (MDM)

Four experiments confirmed the widely accepted hypothesis that, although children as young as two engage in pretend play, even four and five year olds do not understand that pretending requires mental representation. Children appear to misconstrue pretense as its common external manifestations, such as actions, until at least age six. (MDM)
