NASHVILLE, Tenn. - Picture a marching band on the football field during halftime. With precise steps, some band members turn and march in a different direction than the rest, spelling out a school's letters or a mascot's shape. Scientists have known for years that to perceive figures against such a busy background, human vision uses color, brightness and direction of motion. But startling new findings reported by Vanderbilt researcher Randolph Blake in the May 14 issue of Science magazine indicate that the human brain can also use the precise timing of subtle visual changes to group elements into objects.
