The studies in section six (of a six part report on the assessment and treatment of deviant behavior in children)investigated questions generated by the application of the treatment model in the experimental class setting (EC 032 210). The first experiment, on attending behavior, was designed to measure the conditionability of attending behavior using a changing schedule of requirements for reinforcement. Manipulation of the reinforcing contingencies were felt to produce measurable changes in the proportion of attending behavior. The experiment on effects of reinforcement, feedback, and punishment on academic response rate was designed to provide data on optimum combinations of consequation variables for improving academic performance. Results were felt to indicate that positive reinforcement and feedback were effective in accelerating rate correct and decelerating error rate. Punishment of specific error responses were noted as proving effective. The experiment on increasing cooperative social interactions with group reinforcement procedures was investigated using six subjects with deviant behavior in a playground situation. The data was felt to suggest that social interactions could be altered through positive reinforcement. (CD)
