Examining Brain Responses Linked to Emotion in Individuals Who Smoke Cigarettes

The study will use functional magnetic resonance imaging and facial coding methods to study individuals who smoke cigarettes. Smoking expectancy (the extent to which one perceives an opportunity to smoke a cigarette) will be manipulated using instructions, and the investigators will examine the effects of this manipulation on two primary endpoints under conditions designed to induce an urge to smoke: (1) brain responses measured using fMRI and (2) subjective affective responses measured using facial coding. Secondary endpoints include self-report measures of the desire to smoke and current affect.
