Favorable offers indicate trials in which participants stood to gain (either by paying a price lower than the participants’ maximum WTP or by selling at a price higher than their minimum WTA), whereas unfavorable offers indicate trials in which participants stood to lose (by paying a price higher than their maximum WTP, or selling at a price lower than their minimum WTA). Notably, differences emerged between favorable and unfavorable offers, such that the right insula and dACC were more active when viewing unfavorable offers, and left NAcc was more activated in response to favorable offers. Clusters are significant at P < 0.001, with a cluster extent threshold k = 5.
