Traditional Gaze Manipulation (IMAGE)
Caption
In this painting of a Jewish Quarter by the 19th-century Dutch painter Salomon Leonardus Verveer, the people in the center of the image are brighter than they would be in a snapshot, which draws your eye toward them. The walls of the buildings focus your attention toward the middle of the image as well. WUSTL computer scientist Cindy Grimm says similar tricks can be used to help people learn difficult visual search tasks, such as scanning mammograms for tumors.
