Forty-seven monkeys were fed 1 of 8 diets between the ages of 1 and 7 months containing full-, half-, or quarter-strength protein or protein and calories using either casein or soy protein. While on the diet, malnourished infants were inactive both socially and nonsocially. When returned to a normal diet, previously malnourished subjects were more agonistic towards familiar peers but more friendly and less agonistic when later paired with unfamiliar monkeys. The data suggest that short periods of early severe malnutrition may protect the individual against adverse social conditions (e.g., isolation) and delay the development of normal social skills.
47只猴子在1至7个月大时被喂食8种饮食中的一种，这些饮食含有全量、半量或四分之一量的蛋白质或蛋白质与热量，使用的是酪蛋白或大豆蛋白。在节食期间，营养不良的幼猴在社交和非社交方面都不活跃。当恢复正常饮食后，之前营养不良的猴子对熟悉的同伴更具攻击性，但后来与不熟悉的猴子配对时则更友好且攻击性更弱。数据表明，早期严重营养不良的短期阶段可能会保护个体免受不利社会条件（如隔离）的影响，并延缓正常社交技能的发展。
