APPLICATION OF DELAYED REINFORCEMENT PROCEDURES TO THE BEHAVIOR OF AN ELEMENTARY SCHOOL CHILD 1

Delayed reinforcement techniques were applied, in a multiple baseline experimental design, to modify the behavior of a mildly maladjusted sixth‐grade child. The following behaviors were chosen for modification: face‐touching, posture, and voice‐loudness. Videotape recordings were made of the subject's behavior during mathematics and spelling periods each day. The recordings from the mathematics period was shown to her after school, and consequences for behavior exhibited during mathematics were dispensed during the after‐school viewing. This delayed reinforcement procedure produced the desired behavior changes during the mathematics period. Tapes from the spelling period, which were taken without the child's knowledge, indicated that the behavior changes generalized to portions of the day other than the mathematics period.
