This chapter and the next focus on developments during the ages of roughly 2 to 12 years. The present chapter discusses parents’ beliefs and behaviors with respect to aspects of their children’s cognitive development. Seven developments are considered: academic performance, intelligence, Piagetian concepts, theory of mind, memory, executive function, and language. As in Chapter 5, beliefs about general milestones of development are also discussed. And, as in most chapters, parents are of interest both as informants with regard to their children’s development and as contributors to development. Also discussed are the cultural differences that emerge in parents’ expectations, which reflect values and related socialization practices. Culture is both a source of parents’ beliefs and a context for attempting to turn them into reality.
