Shifting from Proactive to Reactive Control: Cognitive Control in Action Video Game Players with Gaming Disorder

While action video games (AVGs) can enhance cognitive control, mechanisms underlying gaming disorder (GD) remain unclear. Using the Dual Mechanisms of Control framework, two task-switching experiments dissociated proactive and reactive control among AVG players with GD, recreational game users (RGU), and non-gamers (NG). Experiment 1 provided initial evidence that, unlike healthy controls, GD players showed difficulty sustaining proactive preparation over extended intervals and tended to rely more on post-response interference resolution. Experiment 2 further supported this reactive dependence: after prolonged delays, switch costs in the GD group dropped to negligible levels, whereas residual costs persisted in RGU and NG groups. These findings provide converging evidence that GD players exhibit relatively fragile proactive control and a compensatory over-reliance on reactive control. Consequently, cognitive impairment in GD reflects a shift in processing mode rather than a generalized deficit, highlighting mechanism-specific targets for clinical interventions.
