The paper, “The tendency to sign-track predicts cue-induced reinstatement during nicotine self-administration, and is enhanced by nicotine but not ethanol“, examined the relationship between Pavlovian conditioned approach (PavCA) and the response to nicotine and alcohol in operant and Pavlovian paradigms.  Cassi found that nicotine (the black dots on the right vs saline-treated white dots), but not alcohol, enhanced sign-tracking, and Chris found that sign-tracking rats were more sensitive to cues during reinstatement to nicotine seeking.  The paper can be found here. Congratulations Cassi and Chris!
