By Lindsay Grice - Shaping, in learning science, refers to gradually teaching a new behaviour through reinforcement until the target behaviour is achieved. Have you ever played the “Hot and Cold” game? As the player gets closer to the prize, you yell “Hotter!” telling him that he’s on the right track. When my horse is on the right track, I reward his approximation of the behaviour. I call this rewarding the thought, or rewarding a try.
