Hewes and Haight question the utility of a multiple act approach for understanding the relationship between traits and communicative behavior. Based upon data collected in two separate studies, they suggest that previous investigations have overestimated the contribution of the multiple-act approach. However, an analysis of their report suggests that their findings are ambiguous and less than compelling. A taxonomy of behavioral measures is explicated to provide a framework for the discussion of the prediction of behavioral criteria. In addition, various approaches to the prediction of single acts are discussed.
