Ambivalence, uncertainty, and processes of candidate evaluation

The on-line and memory-based processing models of candidate evaluation can be better understood by incorporating the concepts of ambivalence and uncertainty, both as subjective feeling states and as objective properties of information. An experiment was designed to address three questions: What are the relationships between ambivalence and uncertainty? What are the informational foundations of subjective ambivalence and uncertainty, and to what extent are they rooted in on-line (time of exposure) and memory-based (time of judgment) processes? What are the consequences of ambivalence and uncertainty for candidate evaluation? The results suggest that (1) subjective uncertainty is more strongly rooted in information about the candidate than is subjective ambivalence; (2) subjective uncertainty and (to a lesser extent) ambivalence are associated with an increased propensity to engage in memory-based processing; and (3) subjective ambivalence and uncertainty result in more negative evaluations, particularly among less sophisticated people. These results suggest ways in which the on-line and memory-based models might productively be combined.
