一组恒河猴（Macaca mulatta）生活在一个大的外壳收到的食物，不同的愿望和空间分布。四个分层亚组的喂养和激动行为进行了分析。在一般情况下，有较少的侵略性和改善喂养率与分散的食物比堆积的食物。高等级受试者的行为是最稳定的：他们通常先吃，吃得最多，很少表现出争斗行为。最低等的受试者也很少出现激动性发作，因为他们倾向于保持在外围，吃得很少。然而，下属更早获得一堆最有价值的食物（香蕉片），而不是一堆不太有吸引力的食物。当香蕉片被分散时，下属也获得了最高的进食分数。后一种情况与攻击性增加有关。中等等级个体的取食行为介于支配个体和从属个体之间，支配个体的攻击行为更强。在涉及限制食物的情况下的行为反映了认知过程，其中包括食物的吸引力，社会地位和所涉及的风险等几个因素进行评估。
A group of rhesus monkeys (Macaca mulatta) living in a large enclosure received food which varied in desirability and spatial distribution. Feeding and agonistic behaviour of four hierarchical subgroups were analyzed. In general, there was less aggression and improved feeding rates with dispersed food than with piled food. The behaviour of high-ranking subjects was the most stable: they usually ate first, ate most, and showed little agonistic behaviour. The most subordinate subjects were also involved in few agonistic episodes, since they tended to remain on the periphery and eat little. However, subordinates obtained access earlier to a pile of the most highly prized food (banana pieces) than to piles of less attractive foods. Subordinates also obtained their highest feeding score when banana pieces were dispersed. This latter condition was associated with increased aggression. The feeding behaviour of intermediate-ranking subjects lay between that of dominants and subordinates, and the former were involved in more aggression. Behaviour in situations involving restricted food reflects cognitive processes in which several factors including attractiveness of the food, social status, and risks involved are evaluated.
