Eight human subjects pressed a lever on a range of variable-interval schedules for 0.25 cent to 35.0 cent per reinforcement. Herrnstein's hyperbola described seven of the eight subjects' response-rate data well. For all subjects, the y-asymptote of the hyperbola increased with increasing reinforcer magnitude and its reciprocal was a linear function of the reciprocal of reinforcer magnitude. These results confirm predictions made by linear system theory; they contradict formal properties of Herrnstein's account and of six other mathematical accounts of single-alternative responding.
八位被试者在一系列变化间隔的强化方案中,用 0.25 美分到 35.0 美分的报酬去按压杠杆。赫尔斯特恩双曲线描述了八位被试者的七种反应率数据。对于所有被试者,双曲线的 y 渐近线随强化物大小的增加而增加,其倒数是强化物倒数的线性函数。这些结果证实了线性系统理论的预测;它们与赫尔斯特恩的描述以及其他六个单一替代反应的数学描述的形式性质相矛盾。
