A Neural Pathway for Nonreinforced Preference Change

Published on May 17, 2020

How is value processed in the brain to inform decision making? A plethora of studies describe how preferences are shaped by experience with external reinforcements. While research on this reinforced pathway is well established, far less research has explored the neural pathways promoting preference change in the absence of external reinforcements. Here, we review behavioral paradigms linking nonreinforced preference change with manipulations of stimulus exposure, response, and gaze position. Based on this work, we propose that several brain regions traditionally associated with selective attention constitute a pathway for nonreinforced preference change.
