Investigated the hypotheses that language-impaired children produce fewer logical propositions per utterance and evidence less control of formal syntactic markers. Matched for mean length of utterance, language samples from 10 language-impaired children approximately five years of age and 10 normal children about three years of age were analyzed.…

The variation of mean length of utterance, a linguistic measure, is explored among 50 normally developing three-, four-, and five-year-olds. It is suggested that mean length of utterance, as a measure of language status, is limited in differentiating language-impaired from normally developing children. (Author/SJL)
