Understanding reinforcement training can't repair physical or neurological deficits, and it won't replace the help that only skilled professionals can give, but it can make life easier for everyone. Parents are learning to shape appropriate behavior instead of accidentally reinforcing inappropriate behavior: to reinforce silence not noise, play, not tantrums. It is not that they are "treating their children like animals", an ever popular prejudiced attack; clicker training is not about animals or people. It is about better ways of teaching and learning. Best of all, you don't need a PH.D to be an effective shaper. Recently I was driving home from an outing with my daughter and her family when her fourteen-month-old began to yell. He wasn't crying-yet, anyway- he was just making a very loud noise to protest the length of the drive and his incarceration in his car seat: and we were still twenty minutes from home. My seven-year-old grandson Wylie, in the backseat with his little brother, calmly got rid of the yelling by reinforcing longer and longer periods of silence. The marker? Wylie's grin. The reinforcer? One lick of Wylie's lollipop.
