Three experiments involving parametric manipulation of reinforcement contingencies were performed with retardates in an automated Sheltered Workshop token economy. Experiment I showed that with amount of reinforcement held constant, work rates were positively related to reinforcement rates on fixed-interval schedules and inversely related to reinforcement rates on fixed-ratio schedules. Experiment II demonstrated an interaction between frequency of ratio reinforcement and torque required to complete a work unit: work rates were positively related to reinforcement rates when required response force was high and negatively related to reinforcement rates when required response force was low. Experiment III revealed that, with reinforcement frequency held constant, there was in inverse relationship between amount of reinforcement and work rate.
三项涉及在自动化庇护工作坊代币经济中对强化时距进行参数操作的实验在智力迟钝者身上进行。实验一表明,在强化量保持不变的情况下,工作率与固定时距时间表上的强化率呈正相关,与固定比率时间表上的强化率呈负相关。实验二证明了比率强化的频率与完成工作单元所需的扭矩之间的相互作用:当所需反应力高时,工作率与强化率呈正相关,当所需反应力低时,工作率与强化率呈负相关。实验三表明,在强化频率保持不变的情况下,强化量与工作率之间呈反比关系。
