Ecott, C. L., Foate, B. A. L., Taylor, B., & Critchfield, T. S. (1999). Further evaluation of reinforcer magnitude effects in noncontingent schedules. Journal of Applied Behavior Analysis, 32, 529-532.

We closely replicated the procedures of a previous study that showed a positive relationship between reinforcer magnitude and the response-rate-reducing effects of noncontingent schedules (NCS). NCS reduced response rates, as expected, but the NCS-magnitude effect was not reproduced, illuminating possible weaknesses of current arbitrary-response procedures and suggesting avenues for future research.

DESCRIPTORS: noncontingent schedules, reinforcer magnitude, developmentally disabled adults
