Developmental psychology and brain research can support campus leaders as they work together with students to prevent the spread of COVID-19 on college campuses and in the surrounding communities. This rapid expert consultation presents research-informed habit-promoting and communication strategies to encourage the adoption of behaviors that can stem the spread of COVID infections on college campuses. The Societal Experts Action Network (SEAN) is an activity of the National Academies of Sciences, Engineering, and Medicine that is sponsored by the National Science Foundation. SEAN links researchers in the social, behavioral, and economic sciences with decision makers to respond to policy questions arising from the COVID-19 pandemic. This project is affiliated with the National Academies' Standing Committee on Emerging Infectious Diseases and 21st Century Health Threats.
