Abstract:
Speech language pathology clinicians use standardized assessments to determine the need for services for children who have language disorders, and sentence repetition is frequently included in the battery of standardized assessments. Sentence repetition is a complex language task that requires comprehension and production of language. Possible cognitive processes involved in processing language for sentence repetition tasks include phonological short-term memory, working memory, and long-term memory. In this study, 16 monolingual English-speakers and 26 bilingual English-speakers completed working memory tasks, nonword repetition tasks, and sentence repetition tasks with varying complexity. Results suggested monolingual speakers relied more on working memory to recall sentences while bilingual speakers relied more on phonological short-term memory.
