A complete developmental reversal in accuracy was obtained in Experiment I in which third graders, sixth graders, and adults judged the class membership of patterns presented in a same-different task. An examination of the task requirements and pattern classes employed led to the hypothesis that the reversal in accuracy resulted from an increase with age in orientation-free judgments. The results of Experiment II, in which adults were told to not rotate the patterns, and Experiment III, which was a replication of Experiment I using symmetric rather than areally skewed pattern classes, provided confirmation for that hypothesis.
