Discriminative responding in pigeons was studied under multiple variable-interval extinction and variable-ratio extinction schedules, as deprivation was varied. Generally, the greater the accuracy of discrimination that developed during training, the smaller the effect of deprivation upon subsequent performance. This was true both in terms of changes in response rates, and in the relationship between response rates during food reinforcement and extinction. When discrimination was inaccurate, increases in deprivation resulted in disproportionate increases in responding during extinction, as compared to increases during food reinforcement components of the schedule. The results suggest that as stimulus control (accuracy) of responding increases, discriminative performance becomes less and less susceptible to influence by deprivation.
在剥夺条件变化的情况下，研究了鸽子在多重可变间隔消退和可变比率消退程序下的辨别性反应。一般来说，训练期间形成的辨别准确性越高，剥夺对后续表现的影响就越小。这在反应率的变化方面以及食物强化和消退期间反应率之间的关系方面都是如此。当辨别不准确时，与程序中食物强化部分的增加相比，剥夺的增加会导致消退期间反应的不成比例增加。结果表明，随着反应的刺激控制（准确性）增加，辨别表现受剥夺影响的程度越来越小。
