Figure 4. Reversal learning and set shifting in the ASST task.

(A) Schematic representation of the behavioural training and testing protocol. The rewarded and unrewarded bowl is indicated with and without the “+”, respectively. The order of the discriminations and the exemplar pairings were always the same, but the pairs of exemplars were counterbalanced between groups. (B) Trials to reach criterion (six successive correct trials) for each phase of the ASST paradigm. (C) Errors made in each phase of the ASST paradigm. *p<0.05; **p<0.001.
