This progress report summarizes the activities from June to August, 1972, of the Experimental Manpower Laboratory for Corrections at Draper Correctional Center. EMLC studies are designed to determine if behavior modification techniques are feasible and provide viable alternatives to aversive control. In the Token Economy (Ecology) Project, inmates are rewarded for socially acceptable behavior on the institution farm, in the basic education component, and in the experimental cellblock. The Contingency Management study, the basic education component, uses a system of contingency contracting covering units of programmed instruction prescribed for each subject on the basis of his pretest score on the Tests of Adult Basic Education. Baseline data for individuals and the group were collected during this report period. Phase I of Correctional Officer Training was completed; it involved completion of self-instructional booklets. Followup studies for 1969 and 1971 are under way. The Lab is also involved in preparing and disseminating a number of measurement and training instruments and publications and technical consultation, conferences, seminars, workshops and other professional activities.
