Description
The overall aim of this project is to examine social, cognitive, and affective processes and their relation to smoking in low hostile and high hostile smokers in an effort to understand better the mechanisms through which hostility impacts smoking. Specifically, we test the hypothesis that nicotine depravation further biases processing of threatening/hostile social information and enhances responding to interpersonal stress in high hostile smokers relative to low hostile smokers. We also test the hypothesis that immediate smoking after an interpersonal stressor, compared to delayed smoking, will be associated with a relatively more steep reduction in negative affect and cigarette craving in high hostile smokers compared to low hostile smokers.
