在觅食的过程中，许多动物会发出特殊的叫声来吸引其他动物。研究人员假设，这些发声的功能是告诉别人关于食物的信息；然而，很少有研究调查与食物有关的叫声是否足以使个体做出反应，就好像它们已经被告知食物一样。对白脸cappuccinus （Cebus capucinus）的回放实验调查了听者是否仅仅通过听到与食物相关的叫声就能推断出食物的存在。与对照组相比，接听电话的人在听到与食物有关的电话后，看向呼叫源的时间明显更长，接近说话者的次数也更多。因为这些反应并不表示进食，所以不清楚听者是否将这些叫声与食物联系在一起。尽管如此，这些特定于与食物有关的叫声的反应可能会增加个体找到食物的机会。
In the context of foraging, many animal species produce specific calls that attract others. Researchers hypothesize that these vocalizations function to inform others about food; however, few studies have investigated whether food-associated calls alone are sufficient to cause individuals to respond as if they have been informed about food. Playback experiments on white-faced captichins (Cebus capucinus) investigated whether listeners could infer the presence of food merely by hearing food-associated calls. Recipients looked significantly longer toward the call source and approached the speaker more often after hearing food-associated calls, as compared with control calls. Because these responses are not indicative of feeding, it is unclear whether listeners associated the calls with food. Nonetheless, these responses, specific to food-associated calls, may increase individuals' chances of finding food.
