P3 event-related potential reactivity to smoking cues: Relations with craving, tobacco dependence, and alcohol sensitivity in young adult smokers.

ABSTRACT: The current study tested whether the amplitude of the P3 event-related potential (ERP) elicited by smoking cues is (a) associated with the degree of self-reported craving reactivity, and (b) moderated by degree of tobacco dependence. Because alcohol and cigarettes are frequently used together, and given recent evidence indicating that individual differences in alcohol sensitivity influence reactivity to alcohol cues, we also investigated whether alcohol sensitivity moderated neural responses to smoking cues. ERPs were recorded from young adult smokers (N = 90) while they participated in an evaluative categorization oddball task involving 3 types of targets: neutral images, smoking-related images, and images of drinking straws. Participants showing larger P3 amplitudes to smoking cues and t
