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.
研究了可变比率强化程序对固定式健身自行车蹬踏效果的影响。三名肥胖和三名非肥胖的11岁男孩每周接受五次单独测试，持续约12周。采用了变化标准设计，其中每个连续标准在前一阶段的平均表现率基础上提高约15%。连续标准的意外情况导致所有儿童的运动率系统性增加。最终的可变比率率高于先前研究中固定比率下的率，三名肥胖男孩中有两名的比率接近非肥胖男孩。
