Behavioural parameters during dPAL task acquisition of all animals. (A) Accuracy; percent of correct choices. (B) Number of trials (black) and number of total trials (trials plus correction trials, grey). (C) Median response latency. (D) Number of additional, i.e. redundant screen touches per trial (trial or correction trial). Group means (± SEM) are shown with ‘ + ’ indicating a significant difference of the respective group to the three other groups and ‘ ~ ’ indicating a significant difference to controls and anhedonic-like rats (Bonferroni post-hoc comparisons; n = 10 for all groups).
