This presentation discusses gender roles and their development from early childhood through adolescence. It explores how gender identity first emerges around 9-12 months as babies distinguish male and female faces, and is usually established by age 2 when children can identify their own gender. Gender constancy, the understanding that gender remains constant regardless of appearance, typically develops between ages 4-5. The presentation also examines the influences of parents, peers, culture and media in shaping perceptions of gender roles, and how gender identity may change during adolescence based on observable behaviors like playmate preference and gender modeling.
