This study used an eye-tracking experiment to investigate how attentional bias toward nicotine-related cues is influenced by craving and moderated by individual differences in impulsivity. Participants completed a Value-Modulated Attentional Capture (VMAC) task that measured their automatic attentional responses to tobacco and monetary reward cues across two phases—before and after a smoking break. The design allowed us to assess how attentional bias fluctuates with physiological states (i.e., high vs. low craving) and whether impulsivity amplifies this effect.
