The hypotheses to be tested in this study are concerned with the use of contingency management. In general, the theory states that behavior normally occurring at a low rate may increase when it is followed by activities which are highly desirable to the student (Premack, 1965). Also suggested in the theory is that a response does not have a zero operant level (Bijou and Baer, 1961). It was assumed, then, that institutionalized offenders enrolled in remedial reading classes have an operant level of some degree for a specific response that could be strengthened by positively reinforcing that response. Because the usual reinforcers for academic learning frequently are not motivating for the offender, an attempt was made to determine the effects of contingency management on reading achievement of adult male felons
