我们报道了成年胡桃钳（Nucifraga科隆比亚纳）和新生雏鸡（Gallus gallus）在根据物体的顺序位置在一系列相同的物体中定位时，表现出一种重复偏误。鸟类被训练以16个相同的排列位置啄第四个或第六个元素。这些被放置在鸟的前面，相对于它的起始位置矢状。在测试中，当系列旋转90°，正面平行于鸟的起始位置时，两个物种都表现出选择性地从左侧识别正确位置的偏好，而不是从右侧。与众所周知的现象的左到右的空间取向的数字线在人类的相似性被认为是。
We report that adult nutcrackers (Nucifraga columbiana) and newborn domestic chicks (Gallus gallus) show a leftward bias when required to locate an object in a series of identical ones on the basis of its ordinal position. Birds were trained to peck at either the fourth or sixth element in a series of 16 identical and aligned positions. These were placed in front of the bird, sagittally with respect to its starting position. When, at test, the series was rotated by 90° lying frontoparallel to the bird's starting position, both species showed a bias for identifying selectively the correct position from the left but not from the right end. The similarity with the well-known phenomenon of the left-to-right spatially oriented number line in humans is considered.
