在这篇文章中，作者结合了与斑块质量有关的信息的计时和贝叶斯修正模型来预测觅食行为。在实验室里，鸽子通过啄两把钥匙(补丁)来获取食物。在每一次试验中，只有一块斑块的食物是预先准备的。在固定的区域找到食物的概率是恒定的，但只有在动物在那里搜索的时候，这种可能性才会积累起来。最优策略是首先选择较好的斑块，并保持固定的持续时间，然后在斑块之间均匀交替。鸽子在3个方面都不是最优的：(A)它们离开得太早，(B)它们的离开时间是可变的，(C)它们在最初离开后对自己的选择有偏见。作者回顾了对这些数据的各种解释。(心理信息数据库记录(C)2019 APA，保留所有权利)
In this article, the authors combine models of timing and Bayesian revision of information concerning patch quality to predict foraging behavior. Pigeons earned food by pecking on 2 keys (patches) in an experimental chamber. Food was primed for only 1 of the patches on each trial. There was a constant probability of finding food in a primed patch, but it accumulated only while the animals searched there. The optimal strategy was to choose the better patch first and remain for a fixed duration, thereafter alternating evenly between the patches. Pigeons were nonoptimal in 3 ways:(a) they departed too early,(b) their departure times were variable, and (c) they were biased in their choices after initial departure. The authors review various explanations of these data.(PsycINFO Database Record (c) 2019 APA, all rights reserved)
