Topic: sign-tracking

Cue reactivity is an important predictor of addiction and relapse. However, it is unclear to what degree it is determined by a trait-like propensity to attribute incentive salience to cues. Animal studies have uncovered that individual variation in such a trait-like propensity expressed behaviorally as “sign-tracking” (ST) is associated with addiction-relevant behavioral and neurobiological features. The current study is first to examine the association between ST and cue reactivity in regular electronic cigarette (ECIG) users. Thirty-seven moderately dependent ECIG users (20 females) were cha
