由于青少年更容易死亡，在面对新的和潜在的威胁情况时，他们可能比成年人更保守。在野外和圈养条件下对长尾猴（Cercopithecus aethiops sabaeus）的研究结果表明，情况正好相反。在野外的幼仔更有可能接近人类观察者，而在圈养中，与年轻和年长的动物相比，它们进入新区域、接近新的食物容器以及与陌生成年雄性动物相距不到一米的时间更短。在所有四种测试条件下，冒险行为都是年龄的倒U型函数。在不熟悉和潜在危险的情况下接近的潜伏期从出生到两岁下降，然后随着年龄的增长而增加到成年。
Because of their greater vulnerability to mortality, juveniles might be expected to be more conservative than adults in response to novel and potentially threatening situations. Results from research on vervet monkeys (Cercopithecus aethiops sabaeus) in the field and in captivity suggest that the opposite is true. juveniles in the field were more likely to approach a human observer, and in captivity they had shorter latencies to enter a new area, approach a novel food container, and come within a meter of a strange adult male when compared to younger and older animals. In all four test conditions, risk-taking was an inverted U-shaped function of age. Latency to approach in unfamiliar and potentially dangerous situations declined from birth to two years of age, then increased with age to adulthood.
