Value-modulated attentional capture (VMAC) refers to the tendency of reward-related cues to automatically capture attention, even when this is counterproductive. VMAC has been well-established in prior research using food and monetary rewards and has been suggested to reflect habit-like behavior that persists despite changes in the motivational state. However, it remains unknown whether VMAC extends to substance use. The main goal of this research was to examine attentional capture by tobacco-related cues following reward devaluation in smokers, as well as the roles of nicotine dependence and bodily intensity in modulating this effect. Fifty-two participants completed measures on nicotine dependence, subjective craving, bodily intensity and a VMAC task across a pre- and post-reward devaluation phase. Results indicate that tobacco-related cues continued to persistently capture attention, despite changes in motivational state. Nicotine dependence did not appear to modulate VMAC. Similarly, bodily sensations were not associated with attentional capture by tobacco-related cues across phases, as bodily sensations increased after tobacco reward devaluation while VMAC remained stable. Together, these findings extend VMAC research to tobacco as a primary reward and suggest that similar mechanisms may operate across different addictive substances. Future research should examine whether these findings generalize to other addictive substances in more clinically representative samples with greater variability in substance dependence.
