Two groups of six mentally retarded adults were exposed to either a "say/do" correspondence training program or a "do only" reinforcement procedure to evaluate the suggestion of Rogers-Warren and Baer (1976) that reinforcement of the nonverbal target behavior in the absence of the relevant verbal behavior may account for the behavior changes seen in correspondence training. The participants worked in an experimental setting on a variety of manipulatory responses leading to various auditory and visual consequences. Analysis of individual patterns of responding indicated no apparent differences between the groups during training; four individuals in each group appeared to develop generalized correspondence skills. We conclude that the outcome of correspondence training may not necessarily be verbal regulation of behavior as is assumed. Rather, we suggest that the notion of rule-governed behavior can best account for the type of behavior changes seen in correspondence studies.

First-grade children engaged in seatwork behaviors under reinforcement schedules established according to the Premack Principle and the Response Deprivation Hypothesis. Across two experiments, schedules were presented to the children in a counter-balanced fashion which fulfilled the conditions of one, both, or neither of the hypotheses. Duration of on-task math and coloring in Experiment 1 and on-task math and reading in Experiment 2 were the dependent variables. A modified ABA-type withdrawal design, including a condition to control for the noncontingent effects of a schedule, indicated an increase of on-task instrumental responding only in those schedules where the condition of response deprivation was present but not where it was absent, regardless of the probability differential between the instrumental and contingent responses. These results were consistent with laboratory findings supporting the necessity of response deprivation for producing the reinforcement effect in single response, instrumental schedules. However, the results of the control procedure were equivocal so the contribution of the contingent relationship between the responses to the increases in instrumental behavior could not be determined. Nevertheless, these results provided tentative support for the Response Deprivation Hypothesis as a new approach to establishing reinforcement schedules while indicating the need for further research in this area. The possible advantages of this technique for applied use were identified and discussed.
