接触新生婴儿是一种商品，可以用来换取其他利益，例如非人类灵长类动物的梳理。根据生物市场范式，支付的价格应该随着群体中新生儿的数量而波动。我们调查了怀有不到 3 个月大婴儿的母亲和其他成年雌性自由放养的灵长类动物之间的梳理情况：一组黑白眉猴 Cercocebus atys，有 35 只成年雌性（科特迪瓦）和两组黑长尾猴 Chlorocebus aethiops，分别有 4 只和 7 只雌性（南非）。尽管白眉猴群体在每个出生季节出生的婴儿比黑长尾猴群体多得多，但涉及婴儿的互动模式显示出许多相似之处：母亲不会回报非母亲提供的梳理，而是直接交换抚摸婴儿的机会，因此，与不涉及婴儿的梳理过程中的往复梳理相比，与婴儿接触需要更长的梳理时间。低级别的驯兽师需要比高级别的驯兽师花费更长的时间来训练母亲。当婴儿长大或当许多婴儿同时出现在群体中时，从母亲接受梳理的时间来看，婴儿的“价值”会下降。在黑长尾黑颚猴中，婴儿的可用性会影响处理时间：当婴儿较少时，雌性处理婴儿的时间会更长。此外，只有母亲经常给婴儿梳理毛发的伙伴才能更长时间地照顾婴儿，而且这种熟悉程度与亲属无关。这表明，如果婴儿的价值随统治地位的不同而变化，那么处理婴儿的时间可能由雌性关系的质量决定。 (c) 2010 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Access to one's newborn infant is a commodity that can be traded for other benefits such as grooming in nonhuman primates. According to the biological market paradigm, the price paid should fluctuate with the number of newborns in the group. We investigated the grooming sessions between mothers with infants less than 3 months old and other adult females in free-ranging primates: one group of sooty mangabeys, Cercocebus atys, with 35 adult females (Ivory Coast) and two groups of vervet monkeys, Chlorocebus aethiops, with four and seven females, respectively (South Africa). Although many more infants were born per birth season in the mangabey group than in the vervet groups, interaction patterns involving infants showed many similarities: mothers did not reciprocate grooming received from non-mothers, but exchanged it directly for the opportunity to handle their infants, whereby obtaining access to infants required longer grooming bouts than reciprocating grooming in grooming sessions not involving infants. Low-ranking handlers needed to groom mothers for longer than their higher-ranking counterparts. The 'value' of an infant, in terms of grooming time received by the mother, decreased when infants grew older or when many infants were simultaneously present in the group. In vervets, infant availability affected handling times: females handled infants for longer when there were fewer infants. Furthermore, only frequent grooming partners of the mother could handle infants for longer and this familiarity was not kin related. This suggests that if the value of an infant varies with dominance, infant handling time may be determined by the quality of the females' relationships.
