The Changing-Criterion Design: Assessment of Running Behavior of a Handicapped Youth

Abstract

In a changing-criterion design increased running speed by a handicapped youth was demonstrated by establishing a temporal criterion for running, which changed repeatedly as running matched the criterion. Reinforcement and avoidance procedures were made contingent on running and were effective in increasing running speed. Follow-up data at 3 and 12 mo. indicated maintenance of the increased running speed.
