A squirrel monkey, if it needs a particular dietary component because of a metabolic disorder or because that food has been excluded from its diet, will develop a specific hunger for the food. In cases where specific hungers show up clearly, four behaviors can be demonstrated: (1) The monkey prefers the food it needs to other foods that are also available; (2) It usually ingests large amounts of the food to meet its particular physiological requirements; (3) The animal will tend to eat the needed food even while the stomach is full; (4) When vitamin B2 is removed from its diet, a squirrel monkey will exhibit digestive disturbance, general weakness, a lack of vigor, and loss of weight.
松鼠猴如果因代谢紊乱或某种食物被排除在其饮食之外而需要特定的饮食成分，就会对这种食物产生特定的饥饿感。在特定饥饿感明显出现的情况下，可以表现出四种行为：（1）与其他也可获得的食物相比，猴子更喜欢它所需要的食物；（2）它通常会大量摄取这种食物以满足其特殊的生理需求；（3）即使胃已经饱了，动物仍会倾向于吃所需的食物；（4）当从松鼠猴的饮食中去除维生素B2时，它会出现消化紊乱、全身虚弱、缺乏活力和体重减轻的情况。
