Chimpanzee problem-solving: a test for comprehension.

An adult chimpanzee was shown videotaped scenes of a human actor struggling with one of eight problems and was then shown two photographs, one of which depicted an action or an object (or both) that could constitute a solution to the problem. On seven of the eight problems, the animal consistently chose the correct photograph. This test problem-solving comprehension permits the animal's knowledge about problem-solving--its ability to infer the nature of problems and to recognize potential solutions to them--to be examined.

Map reading by chimpanzees.

Infant chimpanzees, after watching a small black-and-white closed-circuit television picture of a familiar caretaker walking out into an outdoor field and disappearing from sight, were more successful in finding the person than if they had been given no such cue; and their performance approximated that which obtained after they had seen the same scene normally, via direct perception.
