By the increase of the mental age of the children with Down syndrome, oral stereognosis ability is fixed from 3 to 5 years and the increase of the number of correct identification was not significant (P>0.05). By the increase of mental age from 3 to 5 years, the time spent on stereognosis was reduced significantly (P<0.05).
