Neural correlates of cognitive dissonance and choice-induced preference change
Izuma first author. Using a rate-rate-choose control condition and two measures of preference, self-report and striatum activity, the study addressed the methodological problem raised about the whole free-choice literature. Making a choice changed both the reported preference and its neural representation, with anterior cingulate and dorsolateral prefrontal activity tracking the degree of dissonance. A later review records that the effect is significant only one-tailed, and no sample size is given.
