研究了53只3岁幼年恒河猴和38只5-8岁成年恒河猴早期饲养经历对优势地位发展的影响。基于先前对育儿行为结果的研究，我们预测母亲抚养的猴子高于同伴抚养的猴子，而同伴抚养的猴子反过来又高于代孕的猴子。同伴抚养（SPR）的受试者。MR组和PR组的幼猴在等级上没有差别，但两种饲养背景下的猴子在3岁时的等级都高于SPR组。与饲养条件无关，地位高的幼鱼在1-3岁之间体重增加最多，这表明地位低可能与早期体重增加减少有关。成年MR动物的排名高于PR和SPR动物，PR动物处于中间位置。这些结果表明，贫穷的早期经历，如成人缺席和有限的社会互动，是恒河猴未来社会成功的有用预测因素。2003年出版于Wiley期刊公司。
We examined the effects of early rearing experience on the development of dominance status in 53 juvenile (age 3) and then in 38 adult (ages 5-8) rhesus macaques. Based-on previous research investigating the behavioral outcomes of nursery-rearing, we predicted that mother-reared outrank peer-only reared (PR) monkeys, which would in turn outrank surrogatel. peer-reared (SPR) subjects. Juvenile MR and PR subjects did not differ in ranks, but monkeys from both rearing backgrounds outranked SPR cage-mates at age 3. Independent of rearing condition, high-ranking juveniles gained the most weight between ages 1-3, suggesting that low status may be associated with decreases in early weight gain. Adult MR subjects outranked both PR and SPR subjects, with PR animals occupying intermediate ranks. These results indicate that impoverished early experiences, such as adult absence and limited social interaction, are useful predictors of future social success in rhesus macaques.
