Primate cognition. The chimpanzee Böbe painting in 1967. Primate cognition is the study of the intellectual and behavioral skills of non-human primates, particularly in the fields of psychology, behavioral biology, primatology, and anthropology. [1]
The chimpanzee is covered in coarse black hair but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing 40–70 kg (88–154 lb) for males and 27–50 kg (60–110 lb) for females and standing 150 cm (4 ft 11 in).
The great apes (Hominidae) show some cognitive and empathic abilities. Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
Cognitive tradeoff hypothesis. The cognitive tradeoff hypothesis argues that in the cognitive evolution of humans, there was an evolutionary tradeoff between short-term working memory and complex language skills. Specifically, early hominids sacrificed the robust working memory seen in chimpanzees for more complex representations and ...
Group of chimpanzees. In primatology, the Machiavellian intelligence or social brain hypothesis describes the capacity of primates to manuever in complex social groups. [1][2] The first introduction of this concept came from Frans de Waal 's book Chimpanzee Politics (1982). In the book de Waal notes that chimpanzees performed certain social ...
Matsuzawa is known for his research on chimpanzee intelligence both in the laboratory and in the wild. His laboratory work consists of the Ai-project, which focuses on the language-like skills, number-concepts, and memory ability of a female chimpanzee named Ai. Started in 1978, it is one of the longest running laboratory research projects on ...
Tool use by non-humans is a phenomenon in which a non-human animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, combat, defence, communication, recreation or construction. Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition.
Pan (genus) Pan. (genus) The genus Pan consists of two extant species: the chimpanzee and the bonobo. Taxonomically, these two ape species are collectively termed panins. [3][4] The two species were formerly collectively called "chimpanzees" or "chimps"; if bonobos were recognized as a separate group at all, they were referred to as "pygmy" or ...
