This study investigated how 50 preschool children (25 girls, 25 boys) evalu
ated the appropriateness of excluding boys and girls from two types of acti
vities (doll play, truck play) and two types of future roles (playing a tea
cher, playing a firefighter) across different exclusion contexts. Children
judged straight-forward exclusion from activities on the basis of gender as
wrong, even if the child's gender was sterrotvpical of the activity. Furth
ermore. they justified these decisions on the basis of moral reasons, such
as equality and unfairness. Children used a mixture of moral and social con
ventional reasoning (including stersotypes), however, to evaluate multiface
ted situations that called for judgments about both inclusion and exclusion
and that included information about the children's past experience with th
e activity.
