Question
Which type of vision is more responsive?
Forwards-Backwards
Up-Down
Answer
Dear Chris,
This is a very theoretical Q. More like somthing in research or academics to do with development of binocular vision.
You may find better results on the net.
Some eg. http://brain.oxfordjournals.org/cgi/pdf_extract/31/1/138

Cant help much,
