Discourse prosody in school-aged childrenfs narratives was investigated to test for developmental changes in global prosodic structure and to characterize the key contrastive features for marking continuation versus completion. Spontaneous narratives were obtained from 42 children (5 to 7 years old) and 14 adult caregivers. The narratives were prosodically transcribed using a formal annotation system that relies on perceptual and acoustic analyses. Metalinguistic judgments of prosodic function and appropriateness were also obtained. Analyses examined the global prosodic structure emergent from metalinguistic judgments as well as the prosodic cues to continuation and completion. Results were that children marked phrases for completion less often and less appropriately than adults. Children and adults both used phrase-final tones and post-boundary pauses to mark continuation versus completion; however, childrenfs overall higher rate of pausing lessened the extent to which continuation and completion were differentiated through pausing.
