domains with patients and their care partners.Purpose Specific language impairment (SLI; see also developmental language disorder) and dyslexia are separate, yet frequently co-occurring disorders that confer risks to reading comprehension and academic achievement. Until recently, most studies of one disorder had little consideration of the other, and each disorder was addressed by different practitioners. However, understanding how the two disorders relate to each other is important for advancing theories about each disorder and improving reading comprehension and academic achievement. The purpose of this clinical focus article is to integrate research on SLI and dyslexia as well as advocate for the consideration of comorbidities in future research and clinical practice. Method The first section reviews definitions as well as inclusionary and exclusionary criteria for SLI and dyslexia. The second section reviews research demonstrating that SLI and dyslexia are different disorders that often co-occur. Studies examining language, working memory, and academic achievement in children with separate versus co-occurring SLI and dyslexia are reviewed. The final section compares and contrasts school identification frameworks for children with SLI and dyslexia and considers the potential benefits of incorporating broad language skills into response to intervention (RTI) assessment frameworks. Conclusions Children with weak language skills are at a high risk of experiencing reading problems, but language difficulties are often hidden from view. Directly addressing language skills within school RTI frameworks can help improve the identification and treatment of children with SLI and dyslexia as well as support improved reading comprehension and academic achievement for all students. Presentation Video https//doi.org/10.23641/asha.13063793.Purpose This review article summarizes programmatic research on sentence diversity in toddlers developing language typically and explores developmental patterns of sentence diversity in toddlers at risk for specific language impairment. Method The first half of this review article presents a sentence-focused approach to language assessment and intervention and reviews findings from empirical studies of sentence diversity. In the second half, subject and verb diversity in three simple sentence types are explored in an archival database of toddlers with varying levels of grammatical outcomes at 36 months of age low average, mild/moderate delay, and severe delay. Results Descriptive findings from the archival database replicated previous developmental patterns. All toddlers with low-average language abilities produced diverse simple sentences by 30 months of age and exhibited greater sentence diversity with first-person I-subjects before third-person subjects. Third-person subject diversity emerged in a developmental sequence, increasing in one-argument copula contexts and one-argument subject-verb sentences before two-argument subject-verb-object sentences. This developmental pattern held across all three outcome groups. Third-person subjects were least diverse for children with severe grammatical delays and were absent in all sentence contexts for two children with severe delays at 36 months. Conclusions Sentence diversity increases gradually and expands in predictable patterns. Understanding these developmental patterns may help identify and treat children who display unexpected difficulty combining different subjects and verbs in flexible ways. Supplemental Material and Presentation Video https//doi.org/10.23641/asha.12915320.Purpose This article provides an overview of five papers appearing together on the topic of "Advances in Specific Language Impairment Research and Intervention," which was the 2019 program in an ongoing series of research symposia presented at the Annual Convention of the American Speech-Language-Hearing Association. Method The article provides a historical context for the set of papers, then a short summation of each paper's content, followed by the identification of overarching themes and working conclusions. Results Each paper provides summations of empirical results, and some papers provide new empirical evidence. Conclusion The papers collectively highlight six points (a) Children with specific language impairment (SLI) are likely to be unidentified among their age peers. (b) There is great need for better identification of children with SLI across developmental levels. (c) Progress is evident toward a better understanding of causal pathways, as examined across different research designs involving comparison of children with typical language acquisition to children with SLI and other possibly co-occurring atypical conditions. (d) Measuring multiple dimensions of language brings enhanced informativeness, with differing outcomes for differing dimensions. (e) Replicated research findings require precision of methods in order to reduce unexplained error variance especially when defining groups. (f) Accurate identification of children with SLI is the first step toward a sound treatment plan for SLI and reading disorders as well. Presentation Video https//doi.org/10.23641/asha.13063721.Purpose In this article, we review the role of retrieval practice on the word learning and retention of children with specific language impairment (SLI). Method Following a brief review of earlier findings on word learning in children with SLI and the assumptions behind retrieval practice, four experiments are described that compared novel words learned in a repeated spaced retrieval condition and those learned in either a repeated study condition or a repeated immediate retrieval condition. Preschool-age children with SLI and their same-age peers with typical language development were the participants in all experiments. https://www.selleckchem.com/products/bemnifosbuvir-hemisulfate-at-527.html The effects of repeated spaced retrieval were assessed through measures of recall of word form and meaning and, receptively, through both picture-pointing and electrophysiological measures. Results Repeated spaced retrieval resulted in greater recall of word form and meaning across the experiments. This advantage was seen not only for word-picture pairs used during the learning period but also when generalization of the word to new pictures was required.
