Jane has a 10-year-old son, named Joey. Every time Joey plays in his room, he makes a big mess, throwing his toys around and his clothes on the floor, drawing on the walls and spilling food and drink on the carpet, etc. Additionally, he never cleans up after he finished playing. Now Jane plans to teach her son to a) stop making a mess when he plays and b) start cleaning up his room after he plays, using operant conditioning. How can she use learning principles to teach her son not to make a mess and clean up after himself? Write detailed, step-by-step instructions for Jane to follow and teach her son not to make a mess and to clean up after himself. Remember to identify the type of relevant stimulus, response, reinforcer, punishment, etc.
