Change Blindness Demonstration

This focus on one sight area results in what is called “change blindness.” In well-known demonstrations of change blindness, you can be looking at two identical pictures with one change between them and miss the change.

In the above video, focus on the picture to see whether you can see the change in the picture. If you cannot, then you were a victim of change blindness. Your visual attention is fixed on one small area at a time. You think you’re seeing the whole picture, but you’re seeing only a little space about the size of your thumbnail when you stretch your hand out before you and put your thumb upright.
