The learning of exclusive-or categories by monkeys (macaca mulatta) and humans (homo sapiens).
Summary of "The learning of exclusive-or categories by monkeys (macaca mulatta) and humans (homo sapiens)."
A central question in categorization research concerns the categories that animals and humans learn naturally and well. Here, the authors examined monkeys' (Macaca mulatta) and humans' (Homo sapiens) learning of the important class of exclusive-or (XOR) categories. Both species exhibited-through a sustained level of ongoing errors-substantial difficulty learning XOR category tasks at 3 stimulus dimensionalities. Clearly, both species brought a linear-separability constraint to XOR category learning. This constraint illuminates the primate category-learning system from which that of humans arose, and it has theoretical implications concerning the evolution of cognitive systems for categorization. The present data also clarify the role of exemplar-specific processes in fully explaining XOR category learning, and suggest that humans sometimes overcome their linear-separability constraint through the use of language and verbalization.

Medical and Biotech [MESH] Definitions
Macaca Mulatta
A species of the genus MACACA inhabiting India, China, and other parts of Asia. The species is used extensively in biomedical research and adapts very well to living with humans.
Macaca Nemestrina
A species of the genus MACACA which inhabits Malaya, Sumatra, and Borneo. It is one of the most arboreal species of Macaca. The tail is short and untwisted.
Macaca Radiata
A species of macaque monkey that mainly inhabits the forest of southern India. They are also called bonnet macaques or bonnet monkeys.
Haplorhini
A suborder of PRIMATES consisting of six families: CEBIDAE (some New World monkeys), ATELIDAE (some New World monkeys), CERCOPITHECIDAE (Old World monkeys), HYLOBATIDAE (gibbons and siamangs), CALLITRICHINAE (marmosets and tamarins), and HOMINIDAE (humans and great apes).
Cercopithecinae
A subfamily of the Old World monkeys, CERCOPITHECIDAE. They inhabit the forests and savannas of Africa. This subfamily contains the following genera: CERCOCEBUS; CERCOPITHECUS; ERYTHROCEBUS; MACACA; PAPIO; and THEROPITHECUS.
