Males and females develop different gender identities because they have acquired different schemas for each gender
A gender schema is a mental representation about gender-related behaviours
Gender schemas are based on the individual's past experience, which will inevitably be affected by their culture
Gender schemas affect how we expect each gender to behave and contain information about appropriate behaviours, clothes, characteristics and roles for males/females
The schemas are quite rigid in young children and are based on sex-role stereotypes
They lead to the formation of in-groups and out-groups - children identify as being a boy/girl (in-group) and recognise the opposite gender is different (out-group)
Children behave in ways that are consistent with their in-group schema and avoid behaviours held in their out-group schema
Individuals focus on and remember behaviours that match their gender schema and ignore/modify information that does not
