This is natural because indeed the ability of children with severe and mild mental retardation is of course different, especially in language. The child's "ability to understand" is reflected in the IQ of each child, if the IQ for mild mental retardation is between 55-60 to 80, then severe mental retardation ranges from 15-20 to 25-30, so the ability to understand this basic vocabulary is different, Raju and Dayat.
