The effects of sentence length and structure on the accuracy of sentence repetition by 13 normal-speaking and 13 language-disordered children were compared. The sentences were from three to five words long and were primarily imperative, active-declarative, negative, and question sentences. All types of three-word sentences were repeated accurately by a greater percentage of language-disordered children than were four- and five-word sentences, but the percentages of children accurately repeating these four- and five-word sentences did not differ significantly. Imperative and active-declarative sentences were repeated accurately by a greater percentage of language-disordered children and with fewer errors than were negative and question sentences. Length and structure had no significant effect on the accuracy of sentence repetition by normal-speaking children. Levels of repetition accuracy varied in the deviant-speaking population, and this appears to have important implications for therapeutic programming.
