The “Monster Study” is an experiment credited to American Psychologist, Wendell Johnson. It was conducted alongside Mary Tudor and was done under Johnson’s supervision at the University of Iowa in 1939.

In the experiment, the psychologist used a negative and positive speech therapy to influence the children’s speech making psychology. However, it got it’s name as the “Monster Study” because Doctors were baffled that one of them could perform such an ugly experiment on twenty-two (22) children who were orphans. In 2001, University of Iowa made a public apology for the experiment.
