Math fact fluency is critical for understanding complex mathematics. Explicit timing interventions have shown promise for improving math fluency, and they may benefit from being paired with group-oriented contingencies. Further, investigations of independent and dependent group-oriented contingencies would help to identify their relative…

Three experiments were conducted with rats in which responses on one lever (labeled the functional lever) produced reinforcers after an unsignaled delay period that reset with each response during the delay. Responses on a second, nonfunctional, lever did not initiate delays, but, in the first and third experiments, such responses during the last…

The effects of two levels of exercise (walking versus jogging) in suppressing the self-stimulatory behavior during academic programming of a 5-year-old boy with autism were examined. Decreased physical self-stimulation and "out of seat" behavior were found only for the jogging condition. Sharp reductions in these behaviors did not return…

This 1-year study investigated use of isolation timeout as a behavioral control intervention with 156 students with emotional disturbance in a special educational facility. Results indicated that 13,000 separate timeouts occurred over the year. Average time in isolation was 23 hours per student. Older students in more restrictive settings spent…
