四只大鼠接受指定一系列不同强化频率的可变间隔计划，使用两种不同浓度的蔗糖和蒸馏水作为强化剂。对于蔗糖，所有四只大鼠的反应率均增加强化频率的负加速函数，该数据与赫恩斯坦方程非常一致；当使用蒸馏水作为强化剂时，四只老鼠中的三只的数据也是如此。 Herrnstein方程中的两个常数的值都与蔗糖浓度相关：随着蔗糖浓度的降低，渐近响应率降低，半最大响应率对应的强化频率增加。
Four rats were exposed to variable-interval schedules specifying a range of different reinforcement frequencies, using sucrose of two different concentrations and distilled water as the reinforcer. With sucrose, the rates of responding of all four rats were increasing negatively accelerated functions of reinforcement frequency, the data conforming closely to Herrnstein's equation; this was also true of the data from three of the four rats when distilled water was used as the reinforcer. The values of both constants in Herrnstein's equation were related to the sucrose concentration: the asymptotic response rate decreased, and the reinforcement frequency corresponding to the half-maximal response rate increased, with decreasing sucrose concentration.
