CS-directed orientating responses (a) and approach responses (b) in rats trained with paired CS-US presentations and in rats receiving non-contingent cocaine (STs paired: n = 10; GTs paired: n = 9; STs unpaired: n = 8; GTs unpaired, n = 8). (a) Paired STs and GTs reliably oriented to the CS relative to their unpaired controls. (b) Paired STs showed significantly higher rates of approaches to the CS than all other groups, suggesting that only they attributed incentive salience to the CS (M; SEM; see Results for anovas; * indicates post hoc comparisons indicating a significant difference between unpaired and paired rats of the same phenotype; # indicates post hoc comparisons indicating a significant difference between paired STs and paired GTs; *,#P < 0.05).
