The development of children's beliefs about social and biological aspects of gender differences.

2 studies examined children's beliefs about the origins of gender differences and addressed 2 main questions: (a) What age-related changes are there in children's beliefs about the contributions of nature and nurture to the development of gender roles? and (b) Do children differentiate between aspects of gender roles that adults believe to be more biologically determined and those they believe to be more socially influenced? 160 4- to 10-year-olds and 32 adults participated in Study 1. Participants were told about a child raised with only opposite-sex individuals and were asked whether the child would grow up to possess a series of gender-stereotyped, biological, and control properties. Until age 9 or 10, children believed that gender-stereotyped properties would develop in an infant regardless of the social context of upbringing. Study 2 provides evidence that children were not merely reporting stereotypical category associations. These studies suggest that young children may have an early bias to view gender categories as predictive of essential, underlying similarities between members, but later come to acknowledge the role of other causal mechanisms (e.g., the social environment) in shaping how category members develop.
