Have you ever wondered how the trainers at Sea World get the 19,000-pound whale to jump 22 feet out of water and perform tricks? They get that whale to go over a rope farther out of the water than most of us can imagine.
So how do the trainers at Sea World do it? The first thing they do is reinforce(强化) the behavior that they want repeated --- in this case, to get the whale to go over the rope.
Positive reinforcement is the key of that simple principle that produces such splendid results. And as the whale begins to go over the rope more often than under, the trainers begin to raise the rope. It must be raised slowly enough so that the whale doesn’t starve.
So we need to set up the circumstances so that people can’t fail. Over-celebrate, under-criticize…and know how far to raise the rope.
A.This is a great challenge |
B.And the whale stays right where it is |
C.If we figure out a way to motivate the whale |
D.They start with the rope below the surface of the water |
E.If we under-criticize, punish and discipline less than expected |
F.Whales are taught that their negative behavior won’t be acknowledged |
G.The simple lesson to be learned from the whale trainers is to over-celebrate |
