Tobacco withdrawal and negative affect: an analysis of initial emotional response intensity and voluntary emotion regulation.
This report used emotion-modulated startle to refine theoretically critical claims about negative affect during tobacco withdrawal. Forty-eight dependent smokers (assigned to either a 24-hr nicotine withdrawal condition or a continued smoking condition) and 48 nonsmokers participated in this study. Participants viewed a series of neutral and unpleasant photographic images and were instructed to enhance, suppress, or maintain their emotional response during specific trials. Participants' startle response was measured before and after this regulation instruction to index 2 components of emotional response: initial negative emotional response intensity and emotion regulation. Compared with the nonwithdrawn groups (continuing smokers and nonsmokers), withdrawal significantly increased self-reported negative affect. However, startle response indicated that emotional response intensity and emotion regulation success were not affected by withdrawal. These results are important because they constrain interpretation of the predominantly self-report literature on the affective consequences of tobacco withdrawal.
