Purpose. Young children with Down syndrome (DS) usually have special difficulty acquiring expressive vocabulary and grammar, and recent studies have indicated that at least from early school ages, their speech production skills also are weaker than can be predicted by their intelligence scores. During the babbling stages, however, children with DS have often been found to produce canonical syllables roughly within a typical timeframe. The first purpose of this dissertation is to determine whether early phonological development in children with DS can best be characterized as delayed but predictable based on mental age, as is the case for early comprehension of vocabulary and syntax, or whether, like vocabulary and grammatical production, speech production is more severely impaired than could be anticipated by the children's cognitive abilities alone. The second purpose of this dissertation is to examine the extent to which early vocabulary delays are associated with deficits in speech sound production.

520 $a Purpose. Young children with Down syndrome (DS) usually have special difficulty acquiring expressive vocabulary and grammar, and recent studies have indicated that at least from early school ages, their speech production skills also are weaker than can be predicted by their intelligence scores. During the babbling stages, however, children with DS have often been found to produce canonical syllables roughly within a typical timeframe. The first purpose of this dissertation is to determine whether early phonological development in children with DS can best be characterized as delayed but predictable based on mental age, as is the case for early comprehension of vocabulary and syntax, or whether, like vocabulary and grammatical production, speech production is more severely impaired than could be anticipated by the children's cognitive abilities alone. The second purpose of this dissertation is to examine the extent to which early vocabulary delays are associated with deficits in speech sound production.
520 $a Method. Measures of consonant inventory and syllable structure level were taken at two points from 50 of the children studied by Warren et al. (2008). Canonical and noncanonical words and utterances, and the initial- and final-consonant inventory were coded during two15-minute videotaped semi-structured conversational samples with a parent at two points in time, 18 months apart.
520 $a Results. For all measures at Time 1 (age &sim;25 months), the children with DS performed equally well or better than their peers without DS (NDS). The reverse was true for all measures at Time 2 (&sim;43 months). Consonant inventory size at Time 1 predicted lexical growth at Time 2 only for the children with DS. For the NDS group of children, 60% of whom began the study with fewer than 2 productive consonants, only Time 1 cognitive scores predicted later lexical growth.
520 $a Conclusion. A clear relationship between slow phonological growth and slow lexical growth at the period of "first word" acquisition was established for children with DS. The results of this study indicate that the phonological skills in young children with DS are delayed beyond the level predictable by mental age at the period of early lexical development.
