Final answer:
The Rehabilitation era was based on the medical model of corrections, which considered criminal behavior as something that could be treated and rehabilitated.
Step-by-step explanation:
The era that was based on the medical model of corrections is most commonly referred to as the Rehabilitation era. This era focused on the idea that criminals could be 'cured' of their behaviors in a manner similar to curing diseases. With the advent of the Rehabilitation era came an increased emphasis on psychological evaluations, treatment programs, and the reintegration of the offender into society. This approach differed significantly from earlier eras, where punishment and isolation were the primary means of dealing with inmates. The Rehabilitation era saw the development of various rehabilitation programs including therapy, educational and vocational training aimed at reducing recidivism and aiding reentry into society.
