Roger Garlock Barker (1903 in Macksburg, Iowa – 1990 in Oskaloosa, Kansas) was a social scientist, a founder of environmental psychology and a leading figure in the field for decades, perhaps best known for his development of the concept of behavior settings and staffing theory.
Barker earned his PhD from Stanford University and spent two years studying with Kurt Lewin. In the 1940s Barker and his associate Herbert Wright from the University of Kansas in Lawrence set up the Midwest Psychological Field Station in the nearby town of Oskaloosa, Kansas, a town of fewer than 2000 people. Barker's team gathered empirical data in Oskaloosa from 1947 through 1972, consistently disguising the town as 'Midwest, Kansas' for publications like One Boy's Day (1952) and Midwest and Its Children (1955). Based on this data, Barker first developed the concept of the behavior setting to help explain the interplay between the individual and the immediate environment.
Possibly one of the most valuable developments of Barker's work was the examination of the way in which the number and variety of behavior settings remains remarkably constant even as institutions increased in size. This was explored in his seminal work with Paul Gump published as Barker, R. and Gump, P. (1964) Big School Small School, Stanford: Stanford University Press. They showed that large schools had a similar number of behavior settings to small schools. A consequence of this was that students could take many different roles in small schools (e.g. be in the school band and the school football team), while in larger schools there was a greater tendency to be selective.
Barker died at his home in Oskaloosa, Kansas in September 1990. He was survived by his wife, Louise Shedd Barker, with whom he collaborated on much of his research.
Barker is the subject of a 2014 biography — The Outsider: The Life and Times of Roger Barker — by award-winning American journalist Ariel Sabar.
