For instance, they can match pictures to objects, count and perform arithmetic, recognize themselves in mirrors, and plan ahead to solve a problem.ĭespite these impressive feats, it is difficult to assign an IQ score to chimpanzees or any other animals, as the concept of IQ is based on human aptitude tests that measure verbal, numerical, and spatial reasoning skills. In captivity, chimpanzees have been trained to solve puzzles and cognitive tasks that require memory, spatial awareness, and abstract reasoning. They also engage in cooperative hunting and sharing of food, as well as grooming and communication rituals that serve to strengthen social bonds and resolve conflicts. Moreover, further studies of other chimpanzees in the wild and captivity have shown that their intelligence is not just limited to mimicking gestures and vocalizations, but also includes complex social skills, tool use, and memory.įor example, chimpanzees in the wild have been observed using sticks and stones as tools to crack open nuts, extract insects from crevices, or fish for termites. However, other researchers questioned the validity of Terrace’s claims and argued that Nim was merely imitating the humans without understanding the meaning of the signs. Terrace claimed that Nim had acquired a vocabulary of over 100 signs and could combine them in novel ways to express new ideas, which he argued was evidence of language use and abstract thinking. The study involved a female chimpanzee named Nim Chimpsky, who was raised by humans and taught sign language. One of the most famous studies of chimpanzee intelligence was conducted by American psychologist and primatologist Dr. However, some studies have been conducted to determine the cognitive abilities and problem-solving skills of chimpanzees, which are among the smartest primates and the closest living relatives to humans. The IQ (Intelligence Quotient) of a chimpanzee is a subject of debate, as there is no universally accepted method or scale to measure the intelligence of animals.
