Rats underwent Pavlovian conditioned approach training over five daily sessions and were classified as goal-trackers (GTs; n = 11), intermediate responders (IRs; n = 6), or sign-trackers (STs; n = 7) based on their lever press and magazine entry number, latency, and probability during Sessions 4 and 5. Data are presented as mean and S.E.M. *** - p < 0.001.
