The Effects of Concrete, Symbolic, and Verbal Reinforcement of the Discrimination Learning of Moderately and Severely Retarded Boys

Description: The present study is an attempt to determine which of several different types of reinforcers is most effective in discrimination learning using institutionalized mentally retarded boys of different intellectual levels as subjects. If one type of reinforcement works more effectively in conditioning one level of institutionalized mentally retarded subject, then that type of reinforcement could be used to greater advantage in controlling behavior than some other, less effective kind of reinforcer.
