The ability to innovate, i.e., to exhibit new or modified learned behaviours, can facilitate adaptation to environmental changes or exploiting novel resources. We hereby introduce a comparative approach for studying innovation rate, the ‘Innovation Arena’ (IA), featuring the simultaneous presentation of 20 interchangeable tasks, which subjects encounter repeatedly. The new design allows for the experimental study of innovation per time unit and for uncovering group-specific problem-solving abilities – an important feature for comparing animals with different predispositions and life histories. We applied the IA for the first time to investigate how long-term captivity affects innovative capacities in the Goffin’s cockatoo, an avian model species for animal innovation. We found that fewer temporarily-captive wild birds are inclined to consistently interact with the apparatus in comparison to laboratory-raised birds. However, those that are interested solve a similar number of tasks at a similar rate, indicating no difference in the cognitive ability to solve technical problems. Our findings thus provide a contrast to previous literature, which suggested enhanced cognitive abilities and technical problem-solving skills in long-term captive animals. We discuss the impact and discrepancy between motivation and cognitive ability on innovation rate. Our findings contribute to the debate on how captivity affects innovation in animals.

使用创新竞技场比较野生和实验室戈芬的凤头鹦鹉。

创新的能力,即展示新的或修改后的习得行为,可以促进适应环境变化或开发新资源。我们在此介绍一种用于研究创新率的比较方法,即“创新竞技场”(IA),其特点是同时呈现 20 个可互换的任务,受试者会反复遇到这些任务。新设计允许对每个时间单位的创新进行实验研究,并揭示特定群体解决问题的能力——这是比较具有不同倾向和生活史的动物的重要特征。我们首次应用 IA 来研究长期圈养如何影响戈芬凤头鹦鹉的创新能力,这种鹦鹉是动物创新的鸟类模型物种。我们发现,与实验室饲养的鸟类相比,较少的临时圈养野生鸟类倾向于始终与该设备进行交互。然而,那些感兴趣的人以相似的速度解决相似数量的任务,这表明解决技术问题的认知能力没有差异。因此,我们的研究结果与以前的文献形成了对比,后者表明长期圈养动物的认知能力和技术解决问题的能力有所提高。我们讨论了动机和认知能力对创新率的影响和差异。我们的发现有助于关于圈养如何影响动物创新的辩论。表明解决技术问题的认知能力没有差异。因此,我们的研究结果与以前的文献形成了对比,后者表明长期圈养动物的认知能力和技术解决问题的能力有所提高。我们讨论了动机和认知能力对创新率的影响和差异。我们的发现有助于关于圈养如何影响动物创新的辩论。表明解决技术问题的认知能力没有差异。因此,我们的研究结果与以前的文献形成了对比,后者表明长期圈养动物的认知能力和技术解决问题的能力有所提高。我们讨论了动机和认知能力对创新率的影响和差异。我们的发现有助于关于圈养如何影响动物创新的辩论。
