A study was conducted using positive reinforcement to increase and maintain the time spent participating in study behavior of a six-year-old female kindergarten student and to introduce the teacher to behavioral change techniques. Attending and non-attending study behaviors were observed during 30-minute independent study periods in the classroom. The S received a star for each two minutes (later, each minute) of appropriate study behavior. She could later exchange the stars for prizes and/or privileges that she valued. Reliability checks were made by comparison observations of the four observers. After six reinforcement sessions, positive reinforcement was discontinued to determine whether gains in study behavior were related to reinforcement. Reinforcement was initiated again after a percentage increase in non-study behavior was noted. Results showed the technique to be a success, but it is felt the experiment might have had a more lasting effect if the study had not been concluded prematurely by the closing of school. (KM)
