Preference formation during and following hard choices. In-choice results: A, Fixation Duration for chosen and rejected items. B, Choice prediction accuracy of total, first and last fixation duration. B, Fixation duration differential (i.e., fixation duration of chosen items minus fixation duration of rejected item) predicted upcoming valuation change of chosen item. C, Brain regions of interest associated with trial-by-trial preference change at the time of decision-making between equally valued items. Post-choice results: D, The interaction effect between experimental condition and correctly remembered choice outcomes was associated with left hippocampus activity. E, The interaction effect between experimental condition and correctly guessed choice outcomes was associated with left hippocampus activity. *p < 0.05; **p < 0.01.
