To determine whether pregnancy influences the response of rhesus monkeys towards infants, 11 females were observed during 15-min exposures to a 1- to 15-day-old infant at 1- to 2-week intervals throughout pregnancy. No evidence was found for increasing willingness to contact infants as pregnancy progressed. The parturition of 5 of these females was observed, which included 1 live breech birth. These primiparae all established ventral contact with their infants at birth, though most of them appeared to passively allow the infant to initiate contact while their own attention was directed at licking the birth fluids.
为了确定怀孕是否会影响恒河猴对婴儿的反应，在整个孕期，每隔1至2周，对11只雌性恒河猴进行观察，每次观察15分钟，让它们接触1至15天大的婴儿。没有发现随着孕期进展，接触婴儿的意愿增加的证据。观察了其中5只雌性恒河猴的分娩过程，其中包括1例活产臀位分娩。这些初产妇在分娩时都与婴儿建立了腹部接触，不过大多数初产妇似乎是被动地让婴儿发起接触，而她们自己则将注意力集中在舔舐分娩液体上。
