In the first five or six sessions on a DRL 20-sec schedule of reinforcement there developed a stable performance characterized by a relatively constant conditional probability of occurrence (IRTs/op) of interresponse times (IRTs) of durations greater than 5 or 6 sec. Extinction and the level of deprivation changed both the overall rate of responding and the form of the function relating the duration of an IRT to its value of IRTs/op. The value of IRTs/op decreased more rapidly for short than for longer IRTs, resulting in the emergence of a finer discrimination of IRT duration.
在按每20秒一次的差别强化低反应率(DRL)强化程序进行的最初五六个时段中,出现了一种稳定的表现,其特征是持续时间大于5或6秒的反应间期(IRT)的出现条件概率(IRT/操作)相对恒定。消退和剥夺水平既改变了总的反应率,也改变了将IRT持续时间与其IRT/操作值相关联的函数形式。短IRT的IRT/操作值比长IRT下降得更快,从而产生了对IRT持续时间更精细的辨别。
