Change Blindness: Can You Spot the Changes?

This online activity lets learners discover to what extent they notice changes to an online image. The activity has two parts. In part one, learners look at a scene and try to notice what happens as the scene changes quickly. The second part of the activity shows a very gradual change. Learners discover that humans do not take in the whole scene, but instead glance at things that interest us, ignoring unimportant details.
