Behavioral results. (a) Raw data results. Correct choices differed significantly between groups (t=3.48, p=0.001, left panel). (b) BED patients showed enhanced switching behavior between the two stimuli (F=8.75, p=0.005). (c). Comparison of modeling parameters revealed that BED patients had a lower decision parameter β. Lower values of β indicate a higher degree of stochastic choices unrelated to the current choice values. Hence, lower values in BED indicate enhanced exploratory choices (t=2.51, p=0.016). BED, binge eating disorder; HC, healthy controls.
