Abstract

Innovation is a key component of behavioral flexibility. When individuals are presented with novel problems, their ability to behave flexibly often relies upon their exploratory tendencies, motivational states and intrinsic traits. Studies of repeated innovation pose additional benefits to understand mechanisms of behavioral flexibility, including measuring persistence, exploration and inhibitory control when learned solutions are blocked. The multi-access box (MAB) paradigm tests repeated innovation without prior training and minimal habituation. We tested fifty adult captive female rhesus macaques (Macaca mulatta) with a MAB to evaluate the role of individual traits on repeated innovation and explore the relationship between inhibitory responses and innovation. We found that exploratory diversity positively predicted repeated innovation, as has been reported for previous studies. We also found that traits such as age and personality influenced innovation, where younger individuals and those that scored high on nervousness had higher innovation scores. However, we did not find any relationship between inhibitory responses and innovation. Our study provides the first assessment of repeated innovation in rhesus macaques using a MAB design and highlights the importance of individual traits for repeated innovation in this species.

恒河猴的创新、抑制和灵活性
创新是行为灵活性的关键组成部分。当个体面临新问题时,他们灵活行动的能力往往依赖于他们的探索倾向、动机状态和内在特征。重复创新的研究为理解行为灵活性的机制提供了额外的好处,包括测量持久性、探索和抑制控制,当学习的解决方案受阻时。multi-access box (MAB)范式测试重复创新,无需事先训练和最小的习惯化。本文对50只圈养雌性恒河猴(Macaca mulatta)进行MAB测试,探讨个体特征对重复创新的影响,并探讨抑制反应与创新之间的关系。我们发现探索性多样性正向预测重复创新,正如之前的研究所报道的那样。我们还发现,年龄和个性等特征会影响创新,其中年轻人和那些紧张程度高的人的创新得分更高。然而,我们没有发现抑制反应和创新之间的任何关系。我们的研究首次使用单抗设计对恒河猴的重复创新进行了评估,并强调了个体特征对该物种重复创新的重要性。

期刊介绍: The objective of the American Journal of Primatology is to provide a forum for the exchange of ideas and findings among primatologists and to convey our increasing understanding of this order of animals to specialists and interested readers alike. Primatology is an unusual science in that its practitioners work in a wide variety of departments and institutions, live in countries throughout the world, and carry out a vast range of research procedures. Whether we are anthropologists, psychologists, biologists, or medical researchers, whether we live in Japan, Kenya, Brazil, or the United States, whether we conduct naturalistic observations in the field or experiments in the lab, we are united in our goal of better understanding primates. Our studies of nonhuman primates are of interest to scientists in many other disciplines ranging from entomology to sociology.
