Interresponse-time distributions were recorded in two components of multiple variable-interval schedules that were varied over several conditions. Values of the exponent for power functions relating ratios of interresponse times emitted per opportunity to ratios of reinforcers obtained in the two components varied with interresponse-time class interval. The exponent (sensitivity to reinforcement) afforded a measure of stimulus control exerted by the discriminative stimuli. Exponents were near zero for short interresponse times, consistent with previous conclusions that responses following short interresponse times are controlled by response-produced or proprioceptive stimuli. Values of exponents increased with longer interresponse times, indicating strong control by exteroceptive stimuli over responses following interresponse times of approximately one second or longer.
在多个变量间隔时间表的两个分量中记录了反应间隔时间分布,这些分量在几个条件下发生了变化。与两个分量中每一个机会所发出的反应时间比与所获得的强化物比相关的幂函数的指数值随反应间隔时间的类间隔而变化。指数(对强化的敏感性)提供了由辨别刺激施加的刺激控制的度量。对于短的反应间隔时间,指数接近零,这与之前的结论一致,即短的反应间隔时间后的反应受反应产生的或本体感受性刺激控制。随着反应间隔时间的延长,指数值增加,表明在外源性刺激对反应间隔时间约为 1 秒或更长的反应的控制作用很强。
