Diana monkeys have been observed to respond to the most likely reason for the call, typically a human or leopard, based on the situation and respond according to that. If they deem a leopard is the more likely predator in the vicinity they will produce their own leopard-specific alarm call but if they think it is a human, they will remain ...
While the chimpanzees outperformed human adults in memorizing briefly presented numbers that appeared on the screen, [1] the researchers found that chimpanzees were less proficient at a variety of other cognitive tasks including imitation, cross-modal matching, symmetry of symbols and referents, and one-to-one correspondence. Matsuzawa came up ...
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 ...
As a concept, it is also conflated with, and mistaken for the Machiavellianism personality construct, which focuses on the affective-interpersonal traits of human beings, such as unemotionality and exploitativeness, while Machiavellian Intelligence deals with the social behaviors of primates and is not focused on immoral actions.
Hosted by comedian Jeff Foxworthy, the original show asked adult contestants to answer questions typically found in elementary school quizzes with the help of actual fifth-graders as teammates ...
Delayed response tasks are often used to study short-term memory in animals. Introduced by Hunter (1913), a typical delayed response task presents an animal with a stimulus such as colored light, and after a short time interval the animal chooses among alternatives that match the stimulus, or are related to the stimulus in some other way.
The Old World species are divided into apes and monkeys depending on the number of cusps on their molars: monkeys have four, apes have five [72] - although humans may have four or five. [78] The main hominid molar cusp ( hypocone ) evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost.
Nim Chimpsky [1] (November 19, 1973 – March 10, 2000) was a chimpanzee used in a study to determine whether chimps could learn a human language, American Sign Language (ASL). The project was led by Herbert S. Terrace of Columbia University with linguistic analysis by psycholinguist Thomas Bever .
