There are many examples of how gender development can be influenced by various factors, including biological, cognitive, and sociocultural influences. Here are a few examples:
Biological: A child's genes and hormones may influence the development of their physical sex characteristics, such as the presence of male or female genitalia. Hormonal differences between males and females may also influence the development of certain brain structures and behaviors, such as aggression or spatial ability.
Cognitive: Children may learn gender roles and expectations through observing and imitating the behaviors of others, or by receiving explicit messages about gender from their parents and other adults. For example, a child may learn that it is appropriate for boys to play with certain types of toys, or that girls should wear dresses, by observing these behaviors in the people around them.
