Rats R. norvegicus were trained to press levers to accumulate food at distant sites. The size of the hoard increased with the distance to the site, but did not vary when the rats had to run uphill or downhill to get it. Persistence in a patch depended on the richness of the alternative patch. Optimality models were developed and modified in light of these data.
对褐家鼠进行训练，使其通过按压杠杆在远处地点储存食物。储存量随着到储存地点距离的增加而增加，但当大鼠必须上坡或下坡去获取食物时，储存量没有变化。在一个区域内的停留时间取决于其他区域的丰富程度。根据这些数据开发并修改了最优性模型。
