Kuhn and Pease (2006) compared hypothesis-testing skills of 11- to 12-year-olds with those
of young adults. They were asked to choose accessories for a charity giveaway, then were
given data based on their selections. To use the data most effectively, participants needed
to
attend to their initial beliefs because the data was to be judged as false
discard all initial beliefs because evidence was designed to contradict all of those ideas
integrate initial beliefs with the new evidence
decide to use all items, which would be most effective
