About Dr. James Carter
Dr. James Carter completed his Ph.D. in Developmental Psychology at Stanford University, where his dissertation examined the long-term cognitive effects of structured media exposure in children under five.
His research has been published in peer-reviewed journals including Child Development and the Journal of Applied Developmental Psychology. He currently holds a research fellowship at a leading child development institute.
Beyond academia, Dr. Carter consults with pediatricians, child life specialists, and school districts to translate developmental science into practical parenting guidance. He is a frequent media contributor, having appeared on NPR's Hidden Brain and contributed expert commentary to The New York Times parenting section.
His work focuses on helping parents and educators understand evidence-based approaches to screen time, language acquisition, bilingual development, and emotional regulation in early childhood.
