The subjects were 30 MR children from three special education centers in the city of Sabzevar with the mental age of 60-72 months as well as 60 normal children from eight preschools affiliated with Sabzevar Department of Social Services in the same mental age range. Data were analysis by descriptive-statistical method, Chi-square, and exact Fisher Test.
