7. The Monster Study
In 1939, a speech pathologist, Dr. Wendell Johnson, visited an orphanage in Iowa to test a hypothesis. Determined to prove that stuttering could be cured, he rounded up a group of 22 orphans. Not all his ‘participants’ had a speech impediment, so he mixed stutterers with non-stutterers. He planned to see if he could induce a stutter in normal children and cure those that already stuttered.

Over the course of five months, Davenport and his assistant used positive reinforcement via praise when addressing the group of stutterers. For the group with normal speech, they constantly criticized the way they spoke. By the time the experiment ended, the orphans who didn’t start with a stutter, had developed one. Those in the negative reinforcement group, that started with a stutter became worse than before. Despite efforts to reverse the stutter of those who suddenly developed them, it was never successful.
