The binding problem is a fundamental issue in neuroscience. The term refers to the fact that the brain processes color, motion, and other visual features separately and in parallel, yet our perception is of a unified world, populated by coherent objects. Here we investigate the binding problem with illusions that show—rather dramatically—that features can bind and rebind to moving objects. We show that this effect depends on the color of the background and on whether observers view the illusions centrally or peripherally.
