Purpose: This systematic review provides a comprehensive summary of the diagnostic accuracy of English language sample analysis (LSA) measures for the identification of developmental language disorder. Method: An electronic database search was conducted to identify English publications reporting empirical data on the diagnostic accuracy of English…

Clinical Question: For young AAE speakers (P), how useful is the Developmental Sentence Scoring (DSS) compared with Index of Productive Syntax (IPSyn) in identifying developmental language disorder (DLD) in the presence of African American English (AAE)? Method: Structured Review. Study Sources: PsycInfo®, Education Source, Education Resources…

This systematic review explores the evolution and impact of corpus-based methodologies in textbook analysis within the field of language education between 2010 and 2024. Utilizing the PRISMA framework, 29 studies were identified and analyzed, highlighting the transition from basic frequency analyses to sophisticated examinations of lexical,…

Early research on the Aspect Hypothesis yielded a rigid developmental sequence for the acquisition of grammatical aspect, in which developing L2 learners applied morphemes to mark aspect in accordance with the inherent lexical aspect of verbal prototypes. While studies from a variety of L2 backgrounds have amassed evidence for this hypothesis,…

This study examined how key factors of FFI (degree of explicitness, L1 similarity, proficiency level, and grammar type) influence the accuracy of production. A total of 22 experimental studies, all of which had Korean participants and productive assessments of speech or writing, were selected for analysis. Results revealed that explicit grammar…

Purpose: Despite the apparent primacy of syntactic deficits, children with developmental language disorder (DLD) often also evidence lexical impairments. In particular, it has been argued that this population have difficulty forming lexical representations that are detailed enough to support effective spoken word processing. In order to better…

This study employed synthetic and meta-analytic techniques to review the literature on the Cognition Hypothesis, which predicts that increasing task complexity influences the quality of second language production. Based on 8 inclusion criteria, 17 published studies were synthesized according to key features. A subset of these studies (k = 9) was…
