Thomas R. Zentall, Cognitive dissonance or contrast?
This commentary on Zentall’s target article focuses primarily on clarifying some postulates and variables in cognitive dissonance theory. I discuss the adaptive motivational functions of dissonance arousal and dissonance reduction, and attempt to clarify some past dissonance experiments and to tease apart a dissonance theory and contrast explanation of effort-justification-type effects. The evidence and arguments reviewed here support the explanatory power of cognitive dissonance theory in a wide variety of circumstances in human and nonhuman animals, but they depend on first defining concepts such as “cognitions” quite broadly, as Festinger did when he originally proposed the theory.
