An anonymous reader writes "Scientists at Harvard have found that people are remarkably bad at noticing when moving objects change in brightness, color, size, or shape. In a paper published yesterday in Current Biology, the researchers present a new visual illusion that "causes objects that had once been obviously dynamic to suddenly appear static." The finding has implications for everything from video game design to the training of pilots. Several videos demonstrating this striking effect can be found at http://visionlab.harvard.edu/silencing/."
