蚂蚁距离地面如此之低，以至于它们所行走的地形的轻微起伏都会导致它们对周围场景的看法发生巨大且不可预测的变化。我们在这里描述了一种运动学习形式的证据，当引导地标从视线中消失时，它可以帮助蚂蚁遵循通常的路线。木蚁被训练接近液晶屏幕上不同位置的垂直条。在不同的实验中，杆要么是静止的，要么是平滑移动的，要么是在两个静止位置之间跳跃的。以这三种方式训练的蚂蚁分别遵循直线、曲线或两条腿的路线。一旦蚂蚁习惯了从不同的起点接近酒吧，酒吧就会在它们接近的过程中消失。尽管缺少地标，蚂蚁仍然经常继续它们的直线、弯曲或两条腿的路径，这表明它们可以通过间歇性的视觉反馈来执行复杂的路线。
Ants are so low to the ground that slight undulations in the terrain over which they navigate will cause large and unpredictable changes to their view of the scene around them. We describe here evidence of a form of motor learning that helps ants follow their usual route when guiding landmarks vanish from sight. Wood ants were trained to approach a vertical bar presented at varying positions on a LCD screen. In different experiments, the bar was either stationary, moved smoothly, or jumped between two stationary positions. Ants trained in these three ways followed straight, curved, or two-leg routes, respectively. Once ants were accustomed to approaching the bar from different starting points, the bar was made to disappear during their approach. Ants often continued their straight or curved or two-leg paths, despite the missing landmark, showing that they can perform complex routes with no more than intermittent visual feedback.
