Navon figure

A Navon figure is made of a larger recognisable shape, such as a letter, composed of copies of a smaller different shape. Navon figures are used in tests of visual neglect.^[1]. David Navon's research demonstrated that global features are perceived more quickly than local features.^[2] Patients with Simultanagnosia have difficulty identifying global features, and when presented with a Navon figure will identify only the local features.^[3]

Example
