Abstract

This study investigated the dynamic aspects of deliberation during economic choice, where options are considered sequentially. Two macaques performed a value-based decision-making task with two risky offers presented sequentially, followed by delay epochs. Surprisingly, subjects gazed at the empty locations of previous offers, with longer fixations increasing the probability of choosing that offer. Orbitofrontal cortex (OFC) activity reflected the value of the gazed offer, even if not the most recent, indicating a reevaluation process linked to upcoming choice. The findings suggest that gazing at empty locations triggers offer reactivation for further evaluation.
