Determinants and effects of attentional bias in smokers

Much research has shown that individuals exhibit an attentional bias to sti muli related to their current concerns or pathologies. Using the emotional Stroop task, we investigated attentional bias in smokers. Ninety-six smoker s either abstained from smoking for 24 hr or smoked normally before color-n aming smoking-related and neutral words. Both a blocked format (smoking and neutral words presented in separate blocks) and an unblocked format (smoki ng and neutral words presented in a mixed random sequence) were used. In th e blocked format, abstinence caused an attentional bias to smoking-related stimuli, and the degree of attentional bias predicted the latency to the fi rst cigarette of the morning. However, different results were obtained from the unblocked version of the task. We conclude that the emotional Stroop t ask is a useful tool to measure attentional bias in smokers and could be us ed in cessation studies.
