Final answer:
Symbolic interactionists believe that gender socialization begins at a young age, with children becoming aware of gender roles by age two or three.
Step-by-step explanation:
According to symbolic interactionists, gender socialization begins at a very young age. Cross-cultural studies have shown that children become aware of gender roles by age two or three, and by four or five, they are already firmly entrenched in culturally appropriate gender roles. Children learn these roles through socialization, which is the process of learning how to behave in a particular way based on societal values and attitudes.
