In a series of experiments examining two species of nonhuman primates, Fagot and his colleagues (Deruelle & Fagot, 1998, Fagot & Deruelle, 1997; Fagot & Tomonaga, 1999) have found that baboons and chimpanzees generally exhibit an effect opposite of humans, showing a local precedence effect in which higher accuracy or faster RTs are recorded with local relevant displays, especially with sparse element arrangements. Humans tested with the same stimuli as the primates revealed the standard global precedence effect.
