The ‘Monster Study’ was a psychological experiment conducted by Dr. Wendell Johnson and Mary Tudor on 22 orphan children in 1939.

Amidst the study’s extremely low ethical standards, its results were never published, for Johnson feared that it would be likened to numerous experiments carried out by the Nazi regime.

Dr. Johnson believed that repeatedly telling a child they were ‘a stutterer’ had the potential to give a completely healthy child a stutter. [1]

22 young orphan children were recruited to partake in Johnson’s study. They were split into two groups: stutterers and non-stutterers.

The 11 children who actually did have a stutter were told that they were perfectly healthy; whereas the remaining 11, who were stutter-free, were told that they needed severe speech therapy to correct their ‘stuttering’.
