To what extent are newborn brains designed to operate over natural visual input? To address this question, we used a high-throughput controlled-rearing method to examine whether newborn chicks (Gallus gallus) show enhanced learning of natural visual sequences at the onset of vision. We took the same set of images and grouped them into either natural sequences (i.e., sequences showing different viewpoints of the same real-world object) or unnatural sequences (i.e., sequences showing different images of different real-world objects). When raised in virtual worlds containing natural sequences, newborn chicks developed the ability to recognize familiar images of objects. Conversely, when raised in virtual worlds containing unnatural sequences, newborn chicks' object recognition abilities were severely impaired. In fact, the majority of the chicks raised with the unnatural sequences failed to recognize familiar images of objects despite acquiring over 100 h of visual experience with those images. Thus, newborn chicks show enhanced learning of natural visual sequences at the onset of vision. These results indicate that newborn brains are designed to operate over natural visual input.
新生大脑在多大程度上被设计用于处理自然视觉输入？为了解决这个问题，我们采用了一种高通量的控制饲养方法，来研究新生小鸡（原鸡）在视觉开始时是否对自然视觉序列具有更强的学习能力。我们选取了同一组图像，并将它们分为自然序列（即展示同一真实世界物体不同视角的序列）或非自然序列（即展示不同真实世界物体不同图像的序列）。当在包含自然序列的虚拟世界中饲养时，新生小鸡发展出了识别熟悉物体图像的能力。相反，当在包含非自然序列的虚拟世界中饲养时，新生小鸡的物体识别能力受到严重损害。事实上，大多数用非自然序列饲养的小鸡尽管对这些图像有超过100小时的视觉体验，却仍无法识别熟悉的物体图像。因此，新生小鸡在视觉开始时对自然视觉序列具有更强的学习能力。这些结果表明，新生大脑被设计用于处理自然视觉输入。
