Change analysis is short-changed: A reply to Benjamin

Argues that L. S. Benjamin's (see PA, Vol. 50:Issue 2) critique of the authors' analysis of the overlap hypothesis suffers from basic flaws in the conceptualization and interpretation of change correlations. In addition, her discussion of difference equations is considered irrelevant both to her critique of the article and to the rate of change measure which she proposes. This measure is shown to be merely a composite change score, which avoids none of the previously discussed difficulties associated with change scores. It is concluded, in agreement with Benjamin, that the literature on change needs to be reexamined, but not in the direction she indicates.
