Groups of three rats were placed in a chamber containing one response lever and one water dispenser. A variety of schedule conditions were explored including fixed ratio, extinction, satiation, fixed interval, fixed time, differential reinforcement of low rates, and discrimination learning. Each group was treated as a single unit, with the collective lever responses emitted by the three rats being the main dependent variable. Group responding was found to be controlled by the reinforcement schedules in an orderly and consistent manner. However, the groups often paused less and responded faster than individual rats working under identical conditions.
将三只大鼠分为一组,放置在一个装有一个反应杆和一个饮水器的实验箱中。研究了多种实验安排条件,包括固定比率、消退、饱足、固定间隔、固定时间、低反应率的差别强化以及辨别学习。每组被视为一个单独的单位,三只大鼠发出的集体杠杆反应是主要的因变量。发现组反应以有序且一致的方式受强化程序控制。然而,这些组通常比在相同条件下单独工作的大鼠停顿更少且反应更快。
