Abstract
Action video games (AVGs) provide an ecologically rich context for examining how sustained cognitive demands relate to behaviorally induced neuroplasticity. In this cross-sectional study, we show that the connectivity differences observed in long-term AVG players, referred to here as gamers, reflect neuroplastic refinements consistent with more efficient neural mechanisms for reducing visuomotor information surprise during decision making. To explain how such adaptations could unfold over time, we utilized the Cognitive Resource Reallocation (CRR) framework, defined as the dynamic redistribution of metabolic and functional resources to support behaviorally relevant neuroplastic adaptation under repeated, demanding task conditions. Using a novel region-cumulative principal component analysis (rcPCA) approach applied to previously published data, we identified the subset of brain regions that best explain inter-subject variability, thereby improving statistical power and reducing the burden of multiple comparisons. Our results suggest that long-term engagement with AVGs may promote more efficient visuomotor decision-making strategies through both top-down cognitive clarity, enabling unobstructed transformation of learned value into goal-directed action, and bottom-up motor readiness, enhancing rapid and skillful action selection. These converging adaptations reduce internal conflict, mitigate uncertainty, and enable more effective translation of sensory input into coherent motor output, supporting the broader view that repeated cognitive challenge is associated with perturbations in neurodynamic equilibria that coincide with functional reorganization and enhanced cognitive ability.
