Wait, reading just a little more reveals:
NOTE: This is a dramatic reenactment of an experiment for a TV documentary. The actual experiment criteria: The children used ranged from 41-59 months. The chimps used ranged from 2-6 y.o. Chimps mature at 13-14 for females, 15-16 for males. The box always contains a sticker. When the child gets the sticker, they trade that in for a food reward. The child is instructed to get the reward any way they can, then the experimenter leaves the room. The test is filmed. When the child is successful, they say "I have got it!" and the experimenter returns to the room and gives them their reward.

Since Robert Pirsig put this very well, I’ll just copy down what he said. I don’t know if this story is based on reality or not, but either way, it’s true.
