Abstract:	This study examines the dynamics of early childhood cognitive development influenced by the duration of screen time exposure using the EVDR mathematical model, which is adapted from an epidemiological framework. The model stratifies the child population into five cognitive development states: optimal, vulnerable, natural delay, screen time-induced delay, and recovery. By incorporating screen time as the primary risk factor, the model illustrates how prolonged exposure accelerates the transition of children into delayed conditions and their potential recovery. An optimal control approach is employed to design effective mitigation strategies for managing screen time, aiming to minimize negative impacts while enhancing the recovery process. Numerical simulations demonstrate that although natural delays decrease, screen time-induced delays remain significant, highlighting the necessity of proper intervention management to support children's cognitive development in the digital era.
