Throughout the year I continued to meet with Jerry on a one-to-one basis, talk with his mother periodically, and work with his teachers as much as possible. Jerry seemed to show slow but steady change toward more desirable behavior. Some behaviors seemed to be extinguished, such as wearing bizarre clothing and making machine noises during class. There were still evidences of baby talk and a tendency to blame others for his difficulties, but these appeared to be much less frequent. Jerry's grades had improved, and there was only an occasional instance of tardiness or the forgetting of class materials. He was certainly not a popular member of his class, but he had made some friends. His teachers were generally pleased with his progress and were eager to try reinforcement procedures with other students. I felt that the reinforcement that the faculty members provided was the most important factor in Jerry's improved behavior.
