A striking blindness to changes in real-world scenes can be induced whenever these changes are made during a saccade, flicker, blink, movie cut, or other such interruption. This blindness provides strong evidence that we never form a stable, detailed representation of the world around us. Instead, it appears that our perceptions are based upon a sparse, "just in time" system that provides stable, detailed representations only of those objects that are being attended.
