ABSTRACT
The role played by experiential factors in determining variation in children’s cognitive growth has been at the heart of much theorizing in developmental psychology. Multiple factors have been cited as contributing to children’s cognitive development. For example, individual differences in home and family environment are hypothesized to play a large role in children’s cognitive growth (e.g. Hewison and Tizard, 1980; Alwin and Thornton, 1984; Hess et al., 1984; Iverson and Walberg, 1984).
