Abstract

Background and aims Uncontrollable gaming behavior is a core symptom of Internet Gaming Disorder (IGD). Attentional bias towards game-related cues may contribute to the difficulty in regulating online gaming behavior. However, the context-specific attentional bias and its cognitive mechanisms in individuals with IGD have not been systematically investigated. Methods We compared individuals with IGD to healthy controls (HC) using a rapid serial visual presentation (RSVP) task to measure temporal attentional bias. By applying game-related and neutral stimuli as targets, we specifically assessed how attentional resources were allocated to game-related stimuli compared to neutral stimuli. Results The IGD group showed enhanced attentional blink effect when a game-related stimulus was the first target and a neutral target was the next, reflecting IGD's difficulty in disengaging from game-related stimuli. Both IGD and HC individuals exhibited decreased accuracy in identifying a neutral first target followed by a game-related second target at shorter lags, indicating increased attentional engagement with game-related stimuli in general. Discussion The results provide a cognitive basis for recurrent and uncontrollable gaming behaviors in individuals with IGD. Game cues have priority in the allocation of attentional resources in individuals with IGD. The results shed new light on the development of specific treatments for IGD.
