Screen use in children and adolescents: Developmental risks, benefits, and educational implications

Abstract

The “war against screens” — the intense parental and societal pushback against children’s and adolescents’ excessive use of smartphones, social media, tablets, and games — was lost from the outset. Modern life is inseparable from screens; even closed communities fail at total prohibition. Cross-national parent movements (Wait Until 8th, Smartphone Free Childhood) and policy responses (age restrictions, phone-free schools in Australia, Brazil, Europe, etc.) reflect these worries. Practical guidance centers on the Surgeon General’s “5 Ds” (Discuss, Do, Delay, Divert, Disconnect) and family media plans rather than prohibition. Historical roots of techno-skepticism are traced to Weizenbaum (1976) and Dreyfus. Part 2 focuses on doomscrolling (“catastrophe scrolling”) – compulsive consumption of distressing news. Evolutionary negativity bias, amygdala activation, and dopamine loops sustain the behavior. Gifted adolescents are particularly vulnerable due to intellectual hyperarousal, high empathy, and still-maturing self-regulation. Preliminary group interventions using gradual behavior shaping show promise in reducing the habit. Part 3 dismantles the popular notions of “brain rot” (Oxford Word of the Year 2024) and Spitzer’s “digital dementia.” Neither is a clinical entity; rigorous evidence for permanent cognitive atrophy from screen use is lacking. Content and context matter far more than the medium itself. Paradoxically, technology use in older adults is associated with lower cognitive-decline risk. Both terms remain useful only as red flags for problematic, addictive patterns that impair sleep, mood, and functioning. Overall, screens cannot be eliminated, but intentional limits, high-quality content, protected sleep, real-world activities, parental modeling, and platform accountability can substantially mitigate risks. The goal is not victory in a lost war, but wiser coexistence.
