Effects of a Variable‐ratio Reinforcement Schedule With Changing Criteria on Exercise in Obese and Nonobese Boys
Year: 1992
Type: article
Abstract: The effects of a variable-ratio schedule of reinforcement on pedaling a a stationary exercise bicycle were examined. Three obese and three nonobese 11-year-old boys were individually tested five times weekly for approximately 12 weeks. A changing-criterion design was used in which each successive criterion was increased over mean performance rate in the previous phase by approximately 15%. The contingencies of the successive criteria resulted in systematic increases in rate of exercise for all children. Final variable-ratio rates were higher than those under fixed ratios found in previous research, with rates for 2 of the 3 obese boys approximating those of the nonobese.
