My professional development as a psychologist began as the field of pediatric psychology was emerging and the opportunity to contribute to the Pioneers in Pediatric Psychology series has stimulated reflection on the interrelationship of these developmental processes. More specifically, I want to share my reflections on the formative role of three factors: the zeitgeist of innovative ideas that drive emergent processes, spawn new fields, and provide new opportunities to make a difference; the core values and defining characteristics of psychology as a behavioral science; and the importance of structures in fostering both disciplinary and personal development.
