Preference was stable, and response latency and the RR exhibited the typical phenotype. A) Mean preference for the info alternative for the last three sessions of training, with individual rats represented as scatter plots. B) Total number of observations for latency to choose, on the last three sessions of training are shown for each trial type. Dashed lines indicate the median latency. A marginally significant difference was found between trial types, where responses in choice trials were faster than in forced (Info and NoInfo) trials. C) Violin plots of the distribution of total RR during the 60 s cue presentations are presented for each cue during the last three sessions of training. Dots indicate the median RR for each cue. A significant effect of cue was found. ^**P < 0.01, ⁺P = 0.06, ns = nonsignificant.
