“…Here are some things that are known: All three mechanisms-dissonance (e.g., Fazio & Cooper, 1983), SEM (e.g., Tesser, Millar, & Moore, 1988), and self-affirmation (Koole, Smeets, van Knippenberg, & Dijksterhuis, 1999)-are associ-ated with affect. Both the dissonance mechanism (e.g., Cooper & Fazio, 1984) and the SEM processes (e.g., Achee, Tesser, & Pilkington, 1994;Tesser, Pilkington, & McIntosch, 1989) are mediated by affect; that is, dissonance reduction and SEM behaviors do not manifest themselves in the absence of affect. Much of this research depends on a misattribution paradigm (e.g., Schachter, 1964;Zillman, 1983); that is, when arousal associated with dissonance or SEM is attributed to an irrelevant source, there is little in the way of dissonance reduction or SEM resolutions.…”
