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] Jules Davidoff also performed research, but in a remote culture, finding opposite results; the participants more readily identified the local features.[3] Patients with simultanagnosia have difficulty identifying global features, and when presented with a Navon figure will identify only the local features.[4] A 2010 study comparing global-local processing in different races,[5] found that East Asians demonstrated significantly stronger global processing than Caucasians.
