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] 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] In a recent study comparing global-local processing in different races,^[5] it was found that East Asians demonstrated significantly stronger global processing than Caucasians.
