- I'm convinced that animals *and* children have 3D visual perception at birth.
- Children, though are slightly different than animals at birth in the way
- that animals have instincts built in.
- I'm not sure that 3D visual perception is the reason that the child and
- the very young animals behaved differently. These animal instincts like
- for example, who their natural enemies are, I think, are connected to the
- reason that they didn't want to walk over the (apparent) edge of a cliff.
-
- Children, on the other hand don't have much in that department. I've seen
- a friends baby crawling dangerously near to the top of the staircase, and
- she would have continued if she hadn't been stopped. Probably, as long as
- babies have something underneath them at any given moment, they feel secure
- and will continue to walk (or crawl) until they realise they haven't, that's
- when it is too late. Only until they have had experience in this will they
- continue to do this, and learn what *not* to do.
-
- If this seems sensible, it's my idea, if not someone else told me to
- write it.
