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.
Wait, reading just a little more reveals:
