Cooperation Island is a citizen-science platform designed for children. This platform is created and run by researchers in the Cooperation Lab at Boston College. On Cooperation Island, children can participate in research studies on their own time. Cooperation Island is in its infancy, and we are eager to get families signed up for Cooperation Island so that they can try out our activities and provide feedback. All of our activities are approved by the Boston College Institutional Review Board and are suitable for children. Participation in Cooperation Island requires parental consent.
