Western scrub-jays (Aphelocoma californica) have been shown to overcome present satiety to cache food they will desire in the future. Here, we show that another corvid, the Eurasian jay (Garrulus glandarius), can distinguish between two distinct future desires and plan for each appropriately, despite experiencing a conflicting current motivation. We argue that these data address the criticisms of previous work, and suggest a way in which associative learning processes and future-oriented cognition may combine to allow prospective behaviour.
西方灌丛鸦(Aphelocoma californica)已被证明能够克服当前的饱腹感,储存它们未来想要的食物。在这里,我们展示了另一种鸦科动物——欧亚松鸦(Garrulus glandarius),尽管它们当前的动机存在冲突,但仍能区分两种不同的未来欲望,并为每种欲望做出适当的计划。我们认为这些数据解决了之前研究的批评,并提出了一种方法,即联想学习过程和面向未来的认知如何结合起来,从而允许进行前瞻性的行为。
