饥饿的鸽子会定期收到食物，这是按键灯响起的信号。按键啄食中止了进食。受试者回答了数千个试验，尽管有偶然的非强化，但随着试验间隔的不同，这些试验的概率也不同。危险函数以持之以恒应对和不应对为主。一旦持之以恒被考虑在内，联合条件作用的线性运算符模型进一步改善了预测。试验期间的应答率与先前的应答率相关。重标度极差分析表明，行为轨迹是一种分数布朗运动。
Hungry pigeons received food periodically, signaled by the onset of a keylight. Key pecks aborted the feeding. Subjects responded for thousands of trials, despite the contingent nonreinforcement, with varying probability as the intertrial interval was varied. Hazard functions showed the dominant tendency to be perseveration in responding and not responding. Once perseveration was accounted for, a linear operator model of associative conditioning further improved predictions. Response rates during trials were correlated with the prior probabilities of a response. Rescaled range analyses showed that the behavioral trajectories were a kind of fractional Brownian motion.
