Psychological research has for decades informed understandings of people-environment-relations and their applications in architecture, urban planning, and other design arenas. This session brings together four senior scientists working in environmental psychology to reflect on the past, present, and future of the subdiscipline. They are asked to pay particular attention to the problems, successes, and still latent potentials in environmental psychology's relationship to the broader environment-behavior field. Organized in collaboration with the Environmental Psychology division of the International Association of Applied Psychology (IAAP), this session is intended to help distinguish the contributions and limitations of a scientific psychological approach to theoretical, methodological, and practical problems at the interface of environment and behavior.
