limitation of gender schema theory?
P - gender identity develops earlier than martin & halverson suggested.
E - longitudinal study of 82 children looked at onset of gender identity. data obtained from twice weekly reports from mothers on their children's language from age 9 to 21 months and videotaped analysis of children playing. key measure of gender identity was taken to be how and when children labelled themselves as boy or girl. occurred around 19 months, almost as soon as they begin to communicate, which suggests children have a gender identity before this but just dont communicate it.
L - may have underestimated children's ability to use gender labels about themselves.
