The authors investigated children's conceptions of the characteristic featu
res of category members and found that their conceptions underwent qualitat
ive developmental changes. They hypothesized that (a) children initially te
nd to perceive category members in terms of individual characteristics (i.e
., internal dispositions and behavioral patterns) and (b) only later do the
y conceive of category members in terms of their shared beliefs and values.
They explored these hypotheses in 2 studies: In Study 1, they investigated
how Protestant and Catholic children in Northern Ireland understood the re
ligious intergroup context in their own country; in Study 2, children in It
aly were presented with a fictional scenario of intergroup conflict and ask
ed to explain the causes of the conflict. The results of both studies confi
rmed the 2 hypotheses.
