Fig 2
Model-neutral regression analysis on the behaviour.
(a) Effects of past rewards and choices on current behaviour in reward trials (mean ± SEM, estimated using the three generalised linear mixed-effect models, GLMM1). **P < 0.01 and *P < 0.05, two-tailed Welch’s t test, Bonferroni-corrected for the two tests performed in each model. HC, healthy control; OCD, obsessive-compulsive disorder; PG, pathological gambling. (b) Effects of past losses and choices on current behaviour in avoidance trials. The format is the same as in (a).
