This study explored the role of Arabic diglossia in the language production of Saudi learners of English as a second language, specifically in regard to the effect context formality has on the rate of negative transfer of certain morphosyntactic structures from Modern Standard Arabic (MSA) and Saudi Arabic (SA). Similar to other varieties of…

When acquiring a second language, learners must become able to perceive the difference between novel sounds ("discrimination") and also associate strings of sounds with distinct vocabulary items ("lexical encoding"). Recent research has questioned whether discrimination is a sufficient or necessary condition for encoding, and…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

The present study aimed to catalogue and compare usage patterns of verb-particle constructions (VPCs) in Modern Standard Arabic and English by native and learner writers. Building upon an analysis of a multi-genre monolingual Arabic corpus, use of both Arabic and English VPCs was explored in a bilingual L1 (first language) Arabic L2 (second…

Over the years, less attention is given to students' spelling skills compared to other areas of literacy achievement like word reading and passage comprehension in relationship to nonmainstream dialect usage. Considering that English spelling is based on the phonological and morphological structures of Mainstream American English (MAE), it is…

The goal of this dissertation is to address several major empirical and theoretical issues related to English-speaking children's difficulties with auxiliary use and inversion in questions. The empirical data on English question acquisition are inconsistent due to differences in methods and techniques used. A range of proposals about the source of…

This dissertation investigates the acquisition of early verb inflection in child Slovenian from morphosyntactic and morphophonological perspectives. It centers on the phenomenon of root nonfinites, particularly the patterns of omission and substitution errors in verb inflection marking. It argues that every acquisition model needs to account…
