Response bias in the monetary reward task.

<p>Evolution of the response bias across blocks in the monetary reward task (A) and correlation between change in response bias (i.e., Logb Block 3 –Logb Block 1) and social anhedonia score, <i>R</i>^<i>2</i> = .058.</p

Response bias in the social reward task.

Schematic representation of the tasks.

<p>A fixation cross appears for 500ms, followed by an empty circle. A short or a long line is then flashed inside the circle for 100ms. Participants have an infinite amount of time to respond before they receive a reward for some of their correct responses.</p

Performance in the social reward task.

Flow chart of the study population.

<p>Patients who received a cumulative dose of < 30 mL/kg of HES (hydroxyethyl starch) 6% 130/ 0.4 were compared with those who had received a cumulative dose of ≥ 30 mL/kg of HES 6% 130/ 0.4.</p
