Abstract
Drift diffusion modeling (DDM) was applied to data from depressed and healthy adults who completed a probabilistic reward task. There were no group differences in reward learning, but depressed participants were slower and less accurate. DDM analyses revealed slower drift rates and wider decision thresholds in depressed versus healthy participants.
