This 8.5 hour workshop will convene experts across sectors and disciplines to consider current research, discuss what is known and areas of uncertainty, methodological challenges, and gaps in current knowledge. Discussion will be organized around neural systems and types of digital technologies (e.g., gaming, social media, and passive media). The primary focus will be on school-age children and adolescents, where a larger body of research is available, while also considering earlier developmental stages where evidence permits.
