Developmental Attentional Protection
Mark's specific concern for children's developing attention in AI-saturated environments — grounded in the principle that attentional circuits are built through use and pruned through disuse, and the developmental consequence that AI-mediated stimulation may systematically reshape the cognitive architecture of the next generation.
Gloria Mark's research has always included attention to developmental trajectories, but the AI moment sharpens the concern. The principle is neurological: the brain builds the circuits it uses and prunes the circuits it does not. Children who grow up in environments of continuous AI-mediated stimulation — every question answered instantly, every pause filled productively, every moment of boredom resolved by a responsive tool — are building attentional circuits optimized for that environment and pruning the circuits that support sustained, self-directed attention in the absence of external stimulation. The concern is not speculative. It follows from the established neuroscience of attentional development and from Mark's own data on how attentional patterns established in digital environments become self-reinforcing.
