The book explains the five primary functions of behavioral scientists: assessment and diagnosis, treatment, education and training, research, and consultation. These functions are matched with the technical work of courts, including intake and detention, screening and diversion, plea bargaining, pretrial proceedings, competency, trials, testimony, and jury process and outcome. Behavioral science functions are also related to the court work of commitment, sentencing, punishment, parole and probation, and discretion. Various aspects of court organization and management are then examined as they may be impacted by the application of behavioral science functions. The five behavioral science functions are matched against the five subsystems of corrections organization: goals and values, technical, structural, psychosocial, and managerial. Case studies illustrate the practical applications. Samples of work opportunities for behavioral scientists in the court and correctional systems are provided, and suggestions for new work are offered. Approximately 500 bibliographic listings are provided along with a subject index.
