Institute of Family Relations in Homemade, December, 1986
A survey asked mothers to keep track of how many times they made negative, compared with positive, comments to their children. They admitted that they criticized ten times for every time they said something favorable. A three-year survey in one city's schools found that the teachers were 75% negative. The study indicated that it takes four positive statements from a teacher to offset the effects of one negative statement to a child.
