How the Brain Learns to See

Normally, babies learn how to look at the world before they can communicate their experiences. The rare cases of people who have been blind all their lives and then had their sight restored offer scientists a unique opportunity to study how we learn to interpret visual signals. MIT professor Pawan Sinha is studying children and adolescents in India who are seeing the world for the first time after treatment for blindness.

Research so far suggests that seeing moving objects is crucial for learning to interpret visual signals in the three-dimensional world. Link -via Digg

I guess our knowledge of what squares are meant to look like make the trained eye see the two squares but at base knowledge you would see the three different shapes because that is what is truly represented. The two squares would be a short cut of sorts.
