In addition; In a third part of the experiment, the chimpanzees had access to the toys, but the candy dispenser released the treats into a container beyond their grasp.
In this scenario, the animals played with the toys for only about five minutes. By comparison, when the chimps did have access to the candy, they entertained themselves with the toys for seven minutes, on average. This suggests to Evans that the chimps actively used the toys as a way to bide their time and were not simply passively distracted by the play items.

Now if we could teach this to the inferior humans, we really would be getting somewhere. Great clips!
