More than ever before, leaders within the field of education are looking to research on basic processes to inform and improve educational practices. Success requires building a reciprocal relationship between the field of education and research on learning and development, similar to what exists between biology and medicine. Key to this effort is the development of an explicit conversation between researchers, practitioners, and policy makers, where the generation of basic processes research deals directly with the problems of practice. The goal of this special section of Mind, Brain, and Education is to provide a platform on which practical insight can be gained from new empirical research on hormones and behavior in development. The special section will extend across several issues to examine the hormones important for maintaining the body's critical regulatory processes, including energy balance, sleep/wake cycles, and growth. We have solicited manuscripts describing original research and we have asked an expert in each subfield to comment on the educational relevance of the findings and to vision the future and potential of basic processes research in this area to inform education.
