Figure 1. Pavlovian Conditioned Approach (PCA).

Figure 1

Rats (n = 47) were classed as sign-trackers (ST), intermediates (IN) or goal-trackers (GT) based on CS-evoked behaviors during 5 days of Pavlovian training. Values represent mean (± SEM) number of lever deflections (panel A), food cup entries (panel B), probability of approaching the lever (panel C), or food cup (panel D), and latency to contact the lever (panel E) or make a food cup entry (panel F).
