Dr. Johnson thought that telling a child who stutters or stutters helps the child overcome his condition and makes his speech understandable, easy and smooth. The experiment was conducted on 22 children, all of whom were orphans, and they were divided into two groups, a group that suffers from stuttering and a group that speaks normally. The group that was suffering from stuttering were told that they were in good condition and did not suffer from anything, and the normal group were told that they needed intensive speech therapy because they were suffering from stuttering.
