Abstract
Although post-choice attitude change phenomenon is relatively well-known, few studies identifi ed the actual neural mechanism of dissonance-induced attitude change, especially focusing on the act of choosing. In an fMRI study, 15 participants were scanned while performing a multiple-alternatives-forced-choice task. Participants fi rst rated attractiveness on various art posters, and 4 different choice sets were configured based on each individual’s rating (3 large sets with 4 alternatives and 1 small set with 2 alter-natives). Each participant chose one item among multiple alternatives in a set and reported perceived choice difficulty and re-rated attractiveness of every presented alternative. Trial-by-trial dissonance-induced attitude change score was defined as difference between the increased attractiveness for a chosen item and the decreased attractiveness for rejected items. Participants reported greater choice difficulty and attitude change when choosing from large sets compared to small sets. Greater choice difficulty was strongly related with larger attitude change. We found that choice difficulty and attitude change on each trial are reliably predicted by activity levels in dACC & insula, and dorsal striatum respectively during choice-making. The dACC and striatum showed stronger functional coupling while making a choice from large sets, which showed greater choice difficulty and attitude change. The same regions were also hired more actively among subjects with larger general attitude change. These results demonstrate that higher choice difficulty leads to greater dissonance-induced attitude change and it is derived by interplay of striatum, dACC, and insula. This adaptive process occurs simultaneously at the moment of choice, not as post-choice rationalization.
