Attentional bias in drug dependence: vigilance for cigarette-related cues in smokers.
Two experiments investigated attentional biases for smoking-related cues in smokers and nonsmokers, using the visual probe task. In Experiment 1, when pictures were displayed for 500 ms, smokers who had made repeated quit attempts showed an attentional bias for smoking-related scenes. Experiment 2 replicated this finding and revealed that when pictures were presented for 2,000 ms, the smoker group as a whole showed vigilance for smoking-related cues, but nonsmokers did not. The findings from the 500-ms exposure condition suggest that initial orienting of attention to smoking cues was associated with repeated unsuccessful attempts at abstinence in smokers. Results are discussed with reference to incentive-sensitization theories of addiction and to component processes of selective attention, such as initial orienting versus maintenance.
