Two groups of four rats each were trained to bar press on a variable-interval 2-min schedule. During training, either 3, 5, or 9 auditory stimuli of various intensities were randomly presented. A direct relationship between stimulus intensity and rate of responding was obtained, but it was more consistent in the group trained initially with three stimuli than for the group that started with nine stimuli. The results are related to the concept of stimulus intensity dynamism and the necessary conditions for the acquisition of stimulus control.
将两组各四只大鼠训练为按照可变间隔2分钟的时间表按压杠杆。在训练期间，随机呈现3、5或9种不同强度的听觉刺激。获得了刺激强度与反应速率之间的直接关系，但在最初用三种刺激进行训练的组中比在以九种刺激开始训练的组中更一致。这些结果与刺激强度动态变化的概念以及获得刺激控制的必要条件有关。
