Urge and Affect: A Facial Coding Analysis of Smokers

This study used an established facial coding system to assess participants' immediate affective responses during a smoking cue exposure protocol. Current smokers, randomly assigned to either a 12-hr smoking-deprived or a smoking-nondeprived condition, were exposed to both smoking and control cues. During exposure, the authors manipulated participants' perceived opportunity to smoke. Participants' reactions to the cues were videotaped and coded using P. Ekman and W. V. Friesen's (1978a) Facial Action Coding System. Information regarding smoking opportunity, although altering participants' expressed affect, had no effect on the strength of their reported urge to smoke. The facial coding data are consistent with previous findings using self-report measures of affect and support the use of facial coding as a sensitive and unobtrusive measure of the affective responses to drug cue exposure.
