“…Although there is some evidence that undifferentiated arousal plays a role in cognitive dissonance (e.g., Cooper, Zanna & Taves, 1978;Croyle & Cooper, 1983;Elkin & Leippe, 1986;Pittman, 1975;Zanna & Cooper, 1974), more recent research stressed the mediating role of negative affect in dissonance reduction (e.g., Elliot & Devine, 1994;Harmon-Jones, 2000, 2001Losch & Cacioppo, 1990; see also Higgins, Rhodewalt & Zanna, 1979;Zanna, Higgins & Taves, 1976). For example, Elliot and Devine (1994) and Harmon-Jones (2000) found that participants reported more psychological discomfort (i.e., felt uncomfortable, uneasy, bothered) and general negative affect after they had just committed themselves to engage in discrepant behaviour, such as writing a counterattitudinal essay, and that affect returned to baseline-levels after changing their attitudes.…”
