黑长尾猴（Cercopithecus aethiops sabaeus）在面对不熟悉和潜在威胁的情况时，在回避行为方面表现出个体差异。我们殖民地之前的研究表明，与母亲保护程度较低的青少年相比，早期经历过高水平母亲保护的青少年对新奇事物的反应更加谨慎。这里报告的研究旨在通过引入新的繁殖成年雄性来实验性地改变母体保护性的范例来验证这一结果。母亲们对新男性的出现做出的反应是，增加了对引入后一年出生的婴儿的母性保护。随后，通过测量放置在四个自然组成的社会群体的家庭围场中的新型食品容器 1 m 范围内的潜伏期，评估了对陌生事物反应的个体差异。婴儿接近的潜伏期和顺序与母亲相同。青少年比母亲当前的行为更早接近并且独立于母亲当前的行为，但是他们接近的潜伏期可以通过实验诱导的他们在婴儿时期所经历的母亲保护性的变化来预测。与出生在常驻男性年份的未成熟婴儿相比，在新男性年份出生的未成熟婴儿更加谨慎，并且接触新刺激的潜伏期明显更长。
Vervet monkeys (Cercopithecus aethiops sabaeus) show individual differences in approach-avoidance behavior when faced with an unfamiliar and potentially threatening situation. Prior research from our colony demonstrated that juveniles who had experienced high levels of early maternal protectiveness were more cautious in response to novelty, compared to juveniles who had had less protective mothers. The research reported here was designed to verify this result in a paradigm that experimentally varied maternal protectiveness through the introduction of new breeding adult males. Mothers responded to the presence of new males by increased maternal protectiveness toward infants born in the year following the introductions. Individual differences in response to the unfamiliar were later evaluated by measuring the latency to approach within 1 m of novel food containers placed into the home enclosure of four naturally composed social groups. Infants approached with the same latency and in the same order as their mothers. Juveniles approached sooner than, and independent of, their mother's current behavior, but their latency to approach could be predicted by the experimentally induced variation in maternal protectiveness they had experienced as infants. Immatures who had been born in New Male years, when maternal protectiveness was high, were more cautious and had significantly longer latencies to approach the novel stimulus compared to immatures who had been born in Resident Male years.
