Abstract
Abstract Introduction Tobacco use disorder (TUD) is shaped by pharmacological and neuropsychological mechanisms, with growing evidence implicating attachment strategies and emotion regulation in its onset and maintenance. A hallmark of TUD is attentional bias (AB), in which smoking-related cues disproportionately capture attention, indicating alterations in cognitive control processes. However, research on AB in TUD has largely overlooked the role of attachment strategies. Methods In this observational case–control study, 110 healthy Italian university students (62 people who smoke, 48 participants who do not smoke) completed the Fagerström Test for Nicotine Dependence and the Attachment Style Questionnaire and performed an eye-tracking task. Each trial presented a prime image (neutral or threatening), followed by a choice between smoking- and care-related images displayed side by side. AB indices included relative fixation time, fixation count, and gaze points. Results People who smoke exhibited reduced AB toward care cues regardless of emotional priming, with no prime-related changes in gaze behavior. AB indices for care- and smoking-related images were determined by smoking status rather than the preceding image. Regression analyses showed that avoidant and dismissing attachment styles significantly predicted AB indices, along with group status. Among people who smoke, nicotine dependence predicted relative fixation time only. Conclusions AB toward smoking cues is influenced not only by smoking status but also by individual attachment patterns. These findings support evidence that attention and choice can dissociate: primes may affect decisions without altering gaze. The results highlight the importance of integrating socio-affective factors into research on drug-related AB.
