在人类中，气质在社会化和个性方面起着重要作用。一些气质，如行为抑制，与患精神疾病的风险增加有关。非人灵长类动物可以作为神经生物学和发育对情绪发育贡献的模型，最近的几项研究已经开始调查非人灵长类动物的气质。在恒河猴中，支配地位是从母亲那里继承下来的，并与类似于气质差异的社会和情感倾向有关。目前的研究评估了幼年恒河猴的气质差异作为母系优势等级的函数。对26名婴儿(13名男性)从出生到6个月大的气质进行了评估，方法包括布拉塞尔顿测试、人类入侵者测试、人类入侵者惊吓、皮质醇应激反应，以及家庭笼子中与同龄人和母亲互动的观察。在整个测试过程中，婴儿与他们的母亲和一小群其他猴子一起在室内/室外跑步。每次跑步的母亲的优势度被评为低/中(N=18，9男)或高/α(N=8，4女)。在人类入侵者测试中，高级母亲的婴儿表现出更多的侵入者导向的攻击性，并减少了惊吓增强。在整个发育过程中，占主导地位的后代的皮质醇和惊吓水平也有所降低，在互动测试中，他们离开母亲的时间更长。这些结果表明，母亲的优势可能反映在婴儿早期的行为反应上。这些发现为未来的研究奠定了基础，这些研究可能会专注于影响优势和气质的因素，如遗传、教养和社会化。这些因素很可能在整个发展中以有意义的方式相互作用。这些结果还表明，未来可能有必要对类似关系进行基于人类的研究，尽管在人类社会中的社会支配地位显然比猕猴社会更复杂。上午好。J.Primatol。2013年，75：65-73。由威利期刊出版公司†于2012年出版
In humans, temperament plays an important role in socialization and personality. Some temperaments, such as behavioral inhibition are associated with an increased risk for psychopathology. Nonhuman primates can serve as a model for neurobiological and developmental contributions to emotional development and several recent studies have begun to investigate temperament in nonhuman primates. In rhesus monkeys, dominance rank is inherited from the mother and is associated with social and emotional tendencies that resemble differences in temperament. The current study assessed differences in temperament in infant rhesus monkeys as a function of maternal dominance rank. Temperament was assessed in 26 infants (13 males) from birth until 6 months of age with a battery that included Brazelton test, human intruder test, human intruder‐startle, cortisol stress reactivity, and home cage observations of interactions with peers and the mother. Throughout testing, infants lived with their mothers and a small group of other monkeys in indoor/outdoor runs. Dominance rank of the mothers within each run was rated as either low/middle (N= 18, 9 male) or high/alpha (N= 8, 4 female). Infants of high‐ranking mothers displayed more intruder‐directed aggression and reduced startle potentiation in the human intruder tests. Dominant offspring also had reduced levels cortisol and startle across development and spent more time away from mothers in the interaction tests. These results suggest that dominance of the mother may be reflected in behavioral reactivity of infants early in life. These findings set up future studies, which may focus on contributing factors to both dominance and temperament such as genetics, rearing, and socialization. Such factors are likely to interact across development in meaningful ways. These results also suggest future human‐based studies of a similar relationship may be warranted, although social dominance is clearly more complex in human than macaque societies. Am. J.
