1.The psychologists Daniel Kahneman and Amos Tversky described the following situation:

The instructors in a flight school adopted a policy of consistent positive reinforcement recommended by psychologists. They verbally reinforced each successful execution of a flight maneuver. After some experience with this training approach, the instructors claimed that contrary to psychological doctrine, high praise for good execution of complex maneuvers typically results in a decrement of performance on the next try.

Is there a simpler explanation for the decreased performance following praise? What does this have to do with chapter 15?

Refer Trosset chapter 15.
