通过6个实验，探讨了在同种食物有剩余时，影响褐家鼠幼鼠偷食频率的因素。发现（a）大鼠会穿过一床颗粒去偷同伴正在吃的特定颗粒，（B）一对中的偷窃频率在几天内没有减少，（c）大鼠偷不熟悉的食物比熟悉的食物更频繁，（d）年轻的大鼠偷年长的大鼠比年长的大鼠偷年轻的大鼠更频繁，（e）饥饿的大鼠比吃饱的大鼠偷更频繁，（f）从麻醉的同种动物那里偷了一粒不熟悉的食物的大鼠随后表现出对该食物的偏好增强。结果表明，食物偷窃是一种积极寻求关于吃什么食物的信息的模式。
Six experiments were undertaken to explore factors affecting young rats' (Rattus norvegicus) frequencies of stealing food from conspecifics when identical food is available in surplus. It was found that (a) rats would walk across a bed of pellets to steal the particular pellet a peer was eating, (b) frequency of stealing within a pair did not decrease over days, (c) rats stole unfamiliar foods more frequently than familiar foods, (d) younger rats stole from older rats more frequently than older rats stole from younger ones, (e) hungry rats stole more frequently than replete rats, and (f) rats that had stolen a pellet of unfamiliar food from an anesthetized conspecific subsequently exhibited an enhanced preference for that food. Results suggest that food stealing is a mode of active seeking of information about what foods to eat.
