对不同分类群的研究揭示了早期生活环境和养育对以后生活特征的重要性。虽然有些人已经证明了早期生活经历如何影响认知能力，但很少有人扭转这一局面，并研究父母或其他照顾者在早期生活中的认知技能如何影响年轻人的健康。在这项研究中，我们探讨了如何照顾者的特点可能会影响代理的适合性的幼崽在合作繁殖带猫鼬（蒙哥蒙戈）。我们对成年猫鼬进行了空间记忆测试，并将结果与这些人照顾的幼崽的成功进行了比较。我们的研究结果表明，在空间记忆任务中，速度和准确性之间存在权衡，在测试竞技场中，那些在杯子之间移动得更快的人会对他们已经检查过的杯子进行更多错误的重新访问。此外，他们的照顾者的准确性预测了未来的生存，但不是幼崽的体重增加，效果与预期相反，由不太准确的人照顾的幼崽更有可能存活到成年。我们的研究还提供了证据，虽然年轻的照顾者在测试中不太准确，但照顾者的年龄对抚养性成熟的年轻人的机会没有影响。我们的研究结果表明，带状猫鼬照顾者的认知特征对他们照顾的年轻人有健康的影响，影响这些年轻人活到成熟的机会。
Studies across diverse taxa have revealed the importance of early life environment and parenting on characteristics later in life. While some have shown how early life experiences can impact cognitive abilities, very few have turned this around and looked at how the cognitive skills of parents or other carers during early life affect the fitness of young. In this study, we investigate how the characteristics of carers may affect proxies of fitness of pups in the cooperatively breeding banded mongoose (Mungos mungo). We gave adult mongooses a spatial memory test and compared the results to the success of the pups those individuals cared for. Our results show a tradeoff between speed and accuracy in the spatial memory task, with those individuals which were faster to move between cups in the test arena making more erroneous re-visits to cups that they had already checked for food. Furthermore, the accuracy of their carer predicted future survival, but not weight gain of the pups and the effect was contrary to expected, with pups that were cared for by less accurate individuals being more likely to survive to adulthood. Our research also provides evidence that while younger carers were less accurate during the test, the age of the carer did not have an impact on the chance of raising young that live to sexual maturity. Our findings suggest that banded mongoose carers’ cognitive traits have fitness consequences for the young they care for, affecting the chance that these young live to maturity.
