Do You See What I See? A Scientist's Journey Into 3D

I heard this interview with Sue Barry on NPR's Fresh Air yesterday afternoon.  It's a great example of both neuroplasticity and embodied cognition.  She was born cross-eyed, and could only see in two dimensions for most of her life, but eventually learned to see in 3D despite claims that she would never be able to if she didn't learn it as a child.  She was unconvinced of the claim after hearing her husband, a space shuttle astronaut, describe his own experience of have to learn how to orient himself in space (due to the lack of gravity) and then re-learn to orient himself back on Earth.  She has her own book called Fixing My Gaze: A Scientist's Journey Into Seeing in Three Dimensions, and Oliver Sacks has a chapter about her in his forthcoming book The Mind's Eye.
