Cognitive-developmental theories of gender development suggest that a child's understanding of gender actively develops and becomes more sophisticated with age
Kohlberg's theory of gender development proposes that gender development progresses through three stages:
Stage 1: Gender Identity (age of 2-3 years): child identifies themselves as male or female and can categorize others, but doesn't recognize the stability of gender
Stage 2: Gender stability (age of 3-5 years): childrealizes their gender is stable but may get confused about non-normativeroles and appearances in others
Stage 3: Genderconstancy (age of 6-8years): child understands that theirs and others' gender is permanent and constant over time and in differentsituations despite changes in physicalappearance
Slaby and Frey (1975) suggests that children have observable stages to gender development and supports Kohlberg’s assumption that children who have acquired constancy will actively seek gender-appropriate models
Bussey and Bandura (1992) found that 4-year-olds reported feeling 'awful' about playing with gender-inappropriate toys, indicating that children behave in gender-typical ways regardless of age and level of gender constancy
Kohlberg’s theory was based on interviews with children as young as 2 years old, but it may be that younger children had more sophisticated concepts of gender than they could express due to still learningtotalk at that age, raising questions about the validity of Kohlberg’s theory
