====Hierarchy of effects theory====
Coleman and Wu (2009) emphasized the similarities between the hierarchy of effects theory and agenda-setting theory, and how the latter can be used to analyze the former.<ref name="Coleman-2009">{{cite journal |last1=Wu |first1=H.

Coleman and Wu's study is not so much focused on the order of these components, but instead on which component, knowledge (level one) and attitude (level two), has a greater effect on public behavior.<ref name="Coleman-2009" />
