But those 60 images per second are the same static, unchanging caricature. It makes more sense to say that the child sees the same image multiple times than to say she sees multiple images.

So how does the child learn to recognise a fully 3-dimensional real-life horse from a single caricature of a horse seen any number of times? Can you explain?

Also, if you were to train a nerual net with a single insance of a caricature of a horse, even if you copied it a million times to create an example set of a million copies, the neural net would still only be able to elarn how to recognise that particular caricature, if that- it would certainly not be able to extract any useful features to recognise real-life horses from that single caricature.
