Abstract

Froman and Hubert (1980) have attempted to show how recently developed prediction analysis techniques may be applied to issues of developmental priority, that is, to clarifying the interrelationship between two developing concepts. Although this work is in some respects an important advance over earlier statistical techniques, it seems to raise new problems: (a) It goes too far in identifying issues of developmental priority (sequence vs. synchrony) with issues of statistical relationship (dependence vs. independence) and thus (b) unjustifiably fails to consider certain information inherent in the data which, although irrelevant to issues of statistical relationship, is highly relevant to issues of developmental priority. The present application of prediction analysis techniques to questions of developmental priority thus raises new difficulties at least as serious as those it resolves.
