Table 1 Distribution of sign- and goal-tracking animals by sex and drug exposure (SAL = saline, NIC = nicotine). A tracking score (see text) was calculated for each rat, based on conditioned approach behavior on the last 4Â days of training. The score was used to classify rats within sex and drug exposure group as goal-trackers, intermediate, or sign-trackers
