[photo-3d] Re: seeing 3-D: innate

[Bruce Springsteen <bsspringsteen@xxxxxxxxx>]

I too was reminded of the "checkerboard pit" experiments as this thread
emerged.  My memory tells me that they placed infants of various ages on
the surface of the glass.  Before a certain age, no distress or preference
to be off the pit area was seen, but with children over that age, the
anxiety was evident.  If my memory is right. that would seem to support
the idea that some kind of depth awareness is *not* present from the
start, but whether that refers to stereoscopic, or motion, or perspective
cues from the checkerboard pattern, would still be a question, as John
(the new guy) Rupkalvis has noted.

C'mon Gabriel - find this study on the web for us - it must be somewhere!
