Abstract: | Two male Japanese monkeys used a mirror to inspect an object attached to their bodies but not directly visible. These monkeys
had been trained previously to use a mirror to guide their hand to a target. In Experiment 1 their behavior in the presence
of a mirror was observed. In Experiment 2 the monkeys used the mirror to locate a picture projected on a screen to the left
or right rear side of the cage. In Experiment 3 the monkeys used a mirror to observe and finally grasp an object attached
behind their heads. Two monkeys who were not trained to use a mirror to obtain an otherwise hidden object did not show such
behavior. |
