Behavioral findings during the monetary incentive delay task in MDD (N=30) and comparison (N=31) subjects.
(A) Reaction time (in ms) in response to the target as a function of reward, loss, or no-incentive cue. (B) Reaction Time difference scores (no-incentive - reward cue; no-incentive - loss cue) reveal significantly reduced relative reaction time speeding in MDD subjects for reward trials (p<0.047) and a similar trend for loss trials (p=0.053).
