The growth and development of 32 cebus monkeys were studied during a period of insult in nutritional or rearing conditions and after rehabilitation. Eight experimental groups of four animals each were subjected to one of four diets--control, protein restricted, calorie restricted, and protein-calorie restricted, and one of two rearing conditions-partial isolation or a comparatively enriched condition-in a 4 x 2 factorial design. The period of insult from 2 to 6 months of age was followed by 6 months of rehabilitation in both diet and rearing conditions. It was found that only diet affected physical growth, but both diet and rearing affected behavioral development and exploratory behavior. Whereas calorie deficiency produced a direct effect on behavior independent of rearing conditions, protein deficiency produced an effect only in combination with rearing restriction. The effect of protein-calorie deficiency had some characteristics in common with each of the other deficiencies. Retardation in rate of behavioral development was less severe than retardation in growth, most notably in the protein-restricted, enriched-rearing group, producing animals who were behaviorally mature for their size. All groups caught up in physical growth during rehabilitation but the protein-calorie restricted groups failed to recuperate completely in exploratory behavior.
对32只僧帽猴在营养或饲养条件受损害期间及恢复后阶段的生长发育情况进行了研究。采用4×2析因设计，将八组实验对象，每组四只动物，分别给予四种饮食之一（对照饮食、蛋白质限制饮食、热量限制饮食和蛋白质 - 热量限制饮食），以及两种饲养条件之一（部分隔离或相对丰富的环境）。在2至6个月龄的损害期之后，在饮食和饲养条件方面都进行了6个月的恢复。结果发现，只有饮食影响身体生长，但饮食和饲养条件都影响行为发育和探索行为。热量缺乏对行为产生直接影响，与饲养条件无关，而蛋白质缺乏仅在与饲养限制相结合时才产生影响。蛋白质 - 热量缺乏的影响与其他每种缺乏情况都有一些共同特征。行为发育速度的迟缓不如生长迟缓严重，最明显的是在蛋白质限制、丰富饲养组中，产生了体型与行为成熟度不匹配的动物。所有组在恢复期间身体生长都赶上了，但蛋白质 - 热量限制组在探索行为方面未能完全恢复。
