Figure 1. Comparison of (A) response bias, (B) reward sensitivity and (C) learning rate for the probabilistic reward task at baseline.

Figure 1.

Bupropion responders in Phase 2 have significantly greater baseline (pretreatment) response bias and reward sensitivity, but not learning rate, compared to non-responders (*p<0.05, **p<0.01). On the other hand, there was no difference on these metrics between responders and non-responders to sertraline. Note that the reward sensitivity and learning rate parameters have been transformed to prevent issues with non-Gaussianity.
