This article argues that 1961 to 1967 was a critical period when federal, state, and academic institutions looked with hope toward emerging methods in behavioral and social psychology to train juvenile justice officials and to treat delinquent children. Reflecting liberal optimism regarding the possibility of reforming individual behavior without structural change, the Juvenile Delinquency and Youth Offenses Control Act of 1961 provided project funding to cities, nonprofits, and universities. Using the University of North Carolina’s Training Center on Delinquency and Youth Crime as a case study, this article examines how federal funding was used for “experiments” with group therapy, youth incarceration, and cocreation of juvenile justice. Though largely inconclusive, these experiments demonstrated the existence of alternatives to the hyperinstitutionalization of juvenile offenders that accelerated after the Supreme Court’s 1967 decision of In re Gault.
