<human>:  How did they get the chimp to say “fake news”?
<bot>: The chimp was trained to say “fake news” using a technique called Pavlovian conditioning. A conditioned stimulus is a signal that predicts the delivery of a reinforcing stimulus. In this case, the conditioned stimulus is the chimp’s trainer saying “fake news,” and the reinforcing stimulus is the chimp being fed. After several repetitions, the chimp associates the conditioned stimulus with the reinforcing stimulus. The chimp will then respond to the conditioned stimulus by emitting the learned response.
