Here’s a fun experiment to try with your friends or family. In a group of people, have someone volunteer to leave the room. Then pick a behavior you want to see that person perform when she or he reenters the room. But you are not going to tell the person what behavior you’ve selected. Rather, you are going to “shape” that behavior by using the old game of “getting hotter or colder.” For example, suppose you want the volunteer to pick up a certain book on a shelf. When that person reenters the room, have everyone else begin clapping their hands as he or she gets closer to picking up the particular book. In no time at all, the volunteer will have picked up the book through the use of shaping.
