The purpose of this paper was to encourage the use of behavior modification in special classes as a substantial aid to present-day needs. It briefly reviews the compelling need for improvement in special education, especially in the two areas of social maturity and motivation. It suggests that behavior modification may be the answer to these needs. It briefly treats some of the objections to the use of behavior modification. However, the main part of this paper was directed toward: (1) an examination of principles concerning behavior modification, (2) a review of techniques currently being practiced, (3) a discussion of these techniques in the light of the principles presented, and (4) a suggestion toward solving the problem of internalizing behavior modification gains
