This manual is designed to help parents apply reinforcement theory in managing their children. The program explains how parents can systematically use consequences to teach children in positive ways. Units include: When to Reinforce; How to Reinforce; Reinforcement and Punishment in Everyday Life; and Why Parents (and Teachers) Goof; the Criticism Trap. Ten units in the text illustrate practical situations in which reinforcement theory might operate to modify adult and child behavior. Write-in exercises follow each unit and answer keys appear at the end of the booklet. The author suggests that this program should be of considerable value to teacher aides, to clinical psychologists serving as group leaders for parent programs, to school social workers, to elementary guidance counselors, to special education teachers and to the average parent.
