鸽子对间歇性强化的经典条件反射试验的反应是对CS的不稳定反应。反应取决于先前的试验是否包含食物，食物或两者兼而有之。线性持续/学习模型使动物进入和退出反应状态，而试验内反应数量的威布尔分布控制着状态内啄食。试验和试验间持续时间的变化导致响应率和概率以及模型参数的相关变化。一个新颖的预测——在长期缺乏食物的情况下，反应率可能稳定在零以上——得到了验证。当用食物的概率实例化时，模型预测了平滑的获取函数，但当用强化的试验对试验记录实例化时，模型预测了更准确的锯齿学习曲线。斯金纳参数只有在啄食可以加速或延迟进食时才占主导地位。这些实验为条件作用和条件作用的逐次解释提供了一个框架，增加了数据中可用的信息，使他们能够更明确地评论复杂的当代动量和条件作用模型。
Pigeons responded to intermittently reinforced classical conditioning trials with erratic bouts of responding to the CS. Responding depended on whether the prior trial contained a peck, food, or both. A linear-persistence/learning model moved animals into and out of a response state, and a Weibull distribution for number of within-trial responses governed in-state pecking. Variations of trial and inter-trial durations caused correlated changes in rate and probability of responding, and model parameters. A novel prediction—in the protracted absence of food, response rates can plateau above zero—was validated. The model predicted smooth acquisition functions when instantiated with the probability of food, but a more accurate jagged learning curve when instantiated with trial-to-trial records of reinforcement. The Skinnerian parameter was dominant only when food could be accelerated or delayed by pecking. These experiments provide a framework for trial-by-trial accounts of conditioning and extinction that increases the information available from the data, permitting them to comment more definitively on complex contemporary models of momentum and conditioning.
