isting efforts. Causal modeling, when combined with meta-analysis, allows researchers to go beyond the limitations of any one data set and generate new understandings across data sets. Constructivism represents an interesting and useful possibility for the examination of human communication. Other scholars should test the assumptions of this model and gather more data because the data pool for this synthesis is extremely limited. Other possible theoretical interpretations exist for these data and those should be considered as well. The goal of synthesizing and representing results among studies within a unifying theoretical framework offers much promise.
