Those methods include measuring progress, rewarding and punishing, ways of using rewards and punishers, ways of giving positive reinforcers and punishers, withholding reinforcers (extinction), letting the child reward himself, spacing giving reinforcers, shaping behavior in small steps, using signals, and building control. Twenty-three activities are next presented, each with a task definition, pretest, and suggested education program. These activities include sitting quietly; building puzzles; coloring; playing with toys, balls, and wagons; toilet training; eating correctly; putting on a pullover shirt, pants, and socks; buttoning buttons; tying shoe laces; brushing teeth; washing; imitating movements, mouth movements, sounds, and words; understanding words and the names of colors; naming objects, actions, and colors; and talking in sentences. Appendixes include materials needed for the activities, suggested reinforcers, sample forms for pre- and posttest, glossary, and applications to blind and deaf children. (LE)
