title: Observational studies of children from diary to ethnogram. A century of progress.
abstract: A survey of methodology within observational study is attempted. Personalized baby biographies are seen to provide a foundation for more rigorous study including time and event sampling utilizing technological aids. The essence of ecology is included within an increasingly objective approach leading up to the possibility of utilization of the principles and practice of ethology. Naturalistic observation can be seen to be a necessary element within modern behavioral study.
