A Developmental Neuroscience Framework for Youth-Centered Digital Media and Implications for Policy

Adolescence is a period of neurobiological development, characterized by heightened reward sensitivity, increased social orientation, and still-developing regulatory systems. In this paper, we examine how these core aspects of adolescent brain development can function both as liabilities within current digital ecosystems and as leverage points for designing healthier, developmentally aligned digital media. Drawing on the scientific literature, we review evidence that features of current digital media platforms systematically exploit these developmental sensitivities, such as intermittent and variable rewards (e.g., notifications), quantified social feedback (e.g., likes), algorithmic personalization, beauty filters, and interactive human-like AI chatbots. We close with a discussion of policy implications for designing safer, developmentally appropriate, and neurobiologically-informed digital spaces.
