The 'Support Problem' is a benchmark test to investigate the understanding of spatial relationships between objects. We tested kea parrots' performance in a paradigm that has previously been studied in primates. Kea perform comparably well to tamarins when they are confronted with a choice between two support devices, one of which has a reward resting on it and the other slightly next to it, or when given a choice between a continuous and a disrupted support. Kea did better than chimpanzees in some tasks in which the perceptual connection of the food to the support was altered. The results indicate that kea are capable of assessing the spatial means-end relationships of this problem spontaneously and in a way that is comparable with primates.
“支撑问题”是一项基准测试，用于研究对物体间空间关系的理解。我们在一个先前已在灵长类动物中进行过研究的范式中测试了啄羊鹦鹉的表现。当面对在两个支撑装置之间进行选择时，啄羊鹦鹉的表现与狨猴相当，其中一个支撑装置上放置着奖励，另一个则稍微在其旁边，或者当在连续支撑和中断支撑之间进行选择时也是如此。在一些食物与支撑之间的感知联系发生改变的任务中，啄羊鹦鹉比黑猩猩表现得更好。结果表明，啄羊鹦鹉能够自发地评估这个问题的空间手段-目的关系，并且其方式与灵长类动物相当。
