Language delay became increasingly apparent with age, and more so in boys than in girls. There was no significant difference between mental ages derived from standard ability tests and corresponding age equivalent scores of a symbolic play test. A developmental progression of play similar to that seen in non-handicapped groups was found. (RH)

Nine infants with Down's syndrome, seven nonhandicapped infants, and one severely handicapped infant were given the choice of listening to familiar nursery rhymes or to the same rhymes with each word reversed so that the rhythms, intonation and stress patterns were kept intact but the words became nonsense.

This study, involving 48 children and adolescents with Down's syndrome, found that chronological age and mean mental age collectively accounted for much of subjects' variability in vocabulary comprehension and syntax comprehension, with total passes on a hearing screening accounting for additional variability.
