Article: A new Australian research indicates that children with a stutter do not suffer disadvantages at school, More than ten percent of children have a stutter by the age of four but they score just as high as other children on tests designed to judge their language, thinking skills and character. Professor Reilly's team studied over 1600 children from Melbourne, Australia. Their mothers had been filling out regular questionnaires since their babies were eight months old and the children were judged by a range of language and behaviour tests when they reached the age of four. Reilly and her colleagues asked the parents to call the study group if their children started showing signs of stuttering. Diagnoses were confirmed by a researcher, who then visited the homes of children with a stutter every month to check on their progress. By the age of four, 181 of the children studied had been diagnosed with a stutter. Follow-up visits to the 181 children who were judged after diagnoses showed just nine no longer had a stutter one year later. Stuttering children scored 5. 5 points higher than that of their non-stuttering children on language tests and 2. 6 points higher on the test of non-verbal intelligence. The researchers said it was possible that stuttering could improve language skills, or that stuttering could result from very fast language development among some children. The research suggests parents of children who stutter are usually advised to wait a year before looking for treatment --which can be expensive -- to see if the stutter goes away by itself, unless the children become very unhappy or stop talking. Question: The author shows the result of the research by _ . Yes or no, is the answer "presenting some statistics"?
No
