Summary
This study investigates the neural correlates of skill acquisition in a complex video game, specifically examining how different training strategies influence cortical recruitment. The research addresses the question of whether training strategies that emphasize cognitive flexibility, such as Hybrid Variable-Priority Training (HVT), lead to more efficient neural processing compared to standard repeated practice (Fixed Emphasis Training, FET). The motivation stems from the need to understand how efficient training regimes reduce attentional demands and reliance on motor networks during the transition from effortful control to automaticity. The study employed a randomized controlled trial design with 75 young adult participants, of whom 66 were included in the final fMRI analysis. Participants were assigned to one of three groups: FET, HVT, or a Control group with limited game exposure. The FET group practiced the "Space Fortress" video game without specific strategic instruction, while the HVT group combined part-task training (isolating sub-components) with variable-priority training (shifting emphasis among components during whole-task play). The Control group received minimal game contact. All participants underwent functional magnetic resonance imaging (fMRI) before and after 30 hours of training. Behavioral performance was measured by total game scores, and neural activity was analyzed using FSL software, focusing on regions of interest associated with attentional control, motor, and sensory cortices. Results indicated that both training groups demonstrated significant behavioral improvements in game scores relative to the Control group. Neuroimaging data revealed that both training groups showed a reduction in activation in attentional control areas, including the right middle frontal gyrus, right superior frontal gyrus, and ventral medial prefrontal cortex, compared to the Control group, which continued to engage these regions post-training. The HVT group exhibited superior neural efficiency, characterized by a further reduction in neural resources in cognitive control regions compared to the FET group. Additionally, the HVT group showed reduced activation in motor and sensory cortices and the posteromedial cortex. These findings suggest that HVT facilitates a more efficient modulation of neural activity, reducing the need for top-down attentional control and reliance on the motor network. The significance of these findings lies in the demonstration that training strategies emphasizing cognitive flexibility and component mastery can accelerate skill acquisition by reducing the cognitive load associated with complex tasks. The study provides evidence that HVT is more effective than simple repeated practice in promoting automaticity and efficient neural resource utilization. This has implications for cognitive rehabilitation and training programs, suggesting that structured strategies that prioritize selective aspects of a task within a whole-task context can enhance learning outcomes and neural plasticity more effectively than unstructured practice.
