蚂蚁的学习行走是研究大脑、身体和环境之间相互作用的极好机会，适应行为由此产生。学习行走是一种具有特定功能的行为，它存储目标周围的视觉信息，以简化视觉归位的计算问题，即导航回到目标。然而，目前还不知道为什么学习走路会有这样的刻板印象。在这里，我们研究了当使用一种简单的基于视点的归位算法时，在一系列虚拟世界中，学习行走形式、视觉环境以及两者之间的交互如何影响归位性能。我们表明，学习步行的理想形式是特定于环境的。我们还证明，在确定理想的学习行走和使用存储的视图进行导航时，远处的全景和中等距离处的小对象，特别是当全景被遮挡时，都是视觉环境的重要方面。在对蚂蚁学习行走的行为研究的背景下，讨论了其含义。
The learning walks of ants are an excellent opportunity to study the interaction between brain, body and environment from which adaptive behaviour emerges. Learning walks are a behaviour with the specific function of storing visual information around a goal in order to simplify the computational problem of visual homing, that is, navigation back to a goal. However, it is not known at present why learning walks take the stereotypical shapes they do. Here we investigate how learning-walk form, visual surroundings and the interaction between the two affect homing performance in a range of virtual worlds when using a simple view-based homing algorithm. We show that the ideal form for a learning walk is environment-specific. We also demonstrate that the distant panorama and small objects at an intermediate distance, particularly when the panorama is obscured, are important aspects of the visual environment both when determining the ideal learning walk and when using stored views to navigate. Implications are discussed in the context of behavioural research into the learning walks of ants.
