Anhedonia and expectancy and mood ratings. Patients with higher self-reported anhedonia scores expressed greater expectations of improvement in response to the no-infusion cue (a). High anhedonia scores also predicted lower impact of expectancies on mood ratings (b) but greater mood modulation by neurofeedback (c). Y-axis indicates expectancy or mood ratings (much better = 3, better = 2, slightly better = 1, no change = 0, slightly worse = −1, worse = −2, and much worse = −3). Error bars represent 95% confidence intervals
