The Neurodevelopmental Implications of Premature Screen Exposure: A Neurobiological and Psychosocial Analysis

Abstract

The advancement of technology has made mobile and screen-based devices ubiquitous as part of daily life. With work and communication being made increasingly reliant on such devices, imagining a life without them appears antiquated and overly rudimentary. However, the question that remains uncertain is at what point in the neurodevelopmental trajectory such devices should be introduced. The present article examines the neurobiological, circadian, and psychosocial consequences of premature and excessive screen exposure, particularly in developing populations. Drawing from research on circadian phototransduction, adolescent reward circuitry, sleep physiology, and digital cognition, this paper argues that early and unregulated exposure to screen-based devices may disrupt normative developmental processes. Furthermore, algorithm-driven engagement systems may exploit immature reward circuitry, compounding these effects. Implications for parenting, education, and policy are discussed.
