Between the laboratory, the school, and the community: the psychology of human development, Toronto, 1916-1956.

In the twentieth century, Canadian psychologists have been involved with the educational system and the community at several points in time. In this article, the psychology of human development as developed at the Department of Psychology at the University of Toronto from 1916 to 1956 is investigated. In a variety of projects, the mental health of children was investigated in educational settings while measures were designed and tested to prevent maladjustment and to promote mental health. Initially, research and intervention aimed at adjusting school children to the educational setting. Later, a critical perspective on social institutions and Canadian society was articulated.
