P3D Children and 3D

Hi All,

The question was already settled about 20 years ago when I had ambitions
about being a psychologist.  (My butterfly mind wandered before I was
committed to a degree course though.)  Children can see in stereo before
they are old enough to tell you about it.

How was such a remarkable conclusion arrived at?  Using a Dual Image
Random Dot Stereogram video.  That looks like two of the Magic Eye things,
and they have to be seen through a normal stereo viewer to see a
foreground object seperated from the background.  If you use a video in
order to have something move across the field of view then the child's
eyes will track it as soon as they are old enough to track a real object.

I can just imagine the fun they had trying to get a baby to attend to the
viewer first though.  :-D
