Relative reinforcer duration was varied in concurrent schedules with a fixed-ratio four changeover requirement. The schedule in effect after each reinforcer was randomly chosen. For all three pigeons, relative response rates overmatched relative reinforcer durations. Time allocation was less extreme and, on the average, matched relative reinforcer duration. In a subsequent manipulation, the level of preference was shown to depend on the size of the changeover requirement. These results are similar to those from related unequal reinforcement-frequency procedures.
在具有固定比率四转换要求的同时性程序中,变化相对强化物持续时间。每个强化物之后有效的程序是随机选择的。对于所有三只鸽子,相对反应率都超过了相对强化物持续时间。时间分配不那么极端,平均而言,与相对强化物持续时间相匹配。在随后的操作中,显示出偏好水平取决于转换要求的大小。这些结果与相关的不等强化频率程序的结果相似。
