Introduction: It is well documented that preschoolers with DLD produce first instances of sentential complement clause sentences later than same-age peers with typical language. However, it remains unknown whether children with DLD are limited in their production of a variety of sentential complement clause sentences. Aims: Using a sentence imitation task, we investigated whether preschoolers with DLD present with deficits in the production of sentential complement clause sentences with matrix clauses that are semantically and syntactically varied. We contrasted these sentences with sentential complement clause sentences that contain matrix clauses that are semantically and syntactically limited. We refer to these matrix clauses as true matrix clauses and formulaic matrix clauses, respectively. Methods and Procedures: Twenty-eight 5-year-old children (DLD, n = 14) participated in this study. The experimental task was a 50-item sentence imitation task. Five complement clause verbs (CCVs)--"think," "know," "guess," "bet," "remember"--were used in sentential complement clause sentences containing either formulaic matrix clauses or true matrix clauses. Outcomes and Results: Although children with DLD presented with lower proficiency in all sentential complement clause sentences, children with DLD did not show significantly greater difficulty with sentences containing true matrix clauses than sentences containing formulaic matrix clauses. Conclusions and Implications Sentential complement clause sentences pose a significant challenge for children with DLD.
