Recognition of line-drawing representations by a chimpanzee (Pan troglodytes).
The ability of a chimpanzee to recognize individuals portrayed in line drawings was evaluated. A 12-year-old female chimpanzee with extensive prior experience in the use of visual symbols matched the line drawings of chimpanzees, humans, and an orangutan with a specific letter of the alphabet. When a line drawing of a familiar individual was presented on the computer screen, the chimpanzee responded by punching a key with the letter of the alphabet that corresponded to the individual's name. Results indicate that the chimpanzee is able to categorize individuals from novel line-drawing representations.
