JSMF is encouraging researchers to pursue new questions using conceptual and methodological approaches that take seriously the trajectories, biological and experiential, and contribute to the ongoing development of cognition and behavior occurring across the lifespan. Individual projects need not cover the full human life span but the reasons for focusing on specific age ranges for study should be fully articulated. Research plans that only propose to document task performance of subjects at different ages (e.g., comparing 15-year-old subjects to 60-year-old subjects) are not responsive to the call for proposals. Please contact if you are interested in applying to this opportunity.
