This dissertation defends a strong version of the view that linguistic surface complexity is the product of interactions between deep syntactic mechanisms and shallow interface-specific mechanisms. I argue that current developments in the theory of locality in Distributed Morphology (Embick 2010, Marantz 2013) impose boundaries on syntactic…

From a usage-based approach, this dissertation explores the relationship between structural variability and discourse subjectivity in a series of interviews from the "New Mexico and Southern Colorado Spanish Survey" (Bills and Vigil 2008). Focusing on the use of cognitive and speech verbs, the analysis will demonstrate that a) structural…

The present study examined the locus responsible for the effect of emotional state on sentence processing in healthy native speakers of Japanese, using event-related brain potentials. The participants were induced into a happy, neutral, or sad mood and then subjected to electroencephalogram recording during which emotionally neutral sentences,…

Languages often use different constructions to convey the same meaning. For example, the meaning of a causative construction in English ("Jen had her computer fixed") is conveyed using an active structure in Korean ("Jen-NOM her computer-ACC fixed"), and yet little is known about how bilinguals represent and process such…

The present study explores the effects of meta-cognitive strategies, working memory capacity (WMC), and syntactic awareness on Chinese EFL learners' L2 reading comprehension. One hundred and sixty-seven Chinese college students who were enrolled in the required English class, aged from 19 to 21 years, participated in this study. A questionnaire…

Background: Grammatical morphology has been shown to be problematic for children with specific language impairment (SLI) or developmental language disorder (DLD). Most research on this topic comes from widely spoken languages, such as English. Despite Welsh being the most extensively spoken indigenous in the UK after English, and Wales being the…

Children categorize native-accented speakers as local and non-native-accented speakers as foreign, suggesting they use accent (i.e., phonological proficiency) to determine social group membership. However, it is unclear if accent is the strongest--AND ONLY--group marker children use to determine social group membership, or whether other aspects of…

Purpose: We assessed the potential direct and indirect (mediated) influences of 4 cognitive mechanisms we believe are theoretically relevant to canonical and noncanonical sentence comprehension of school-age children with and without developmental language disorder (DLD). Method: One hundred seventeen children with DLD and 117 propensity-matched…

Most current models of sentence comprehension assume that the human parsing mechanism (HPM) algorithmically computes detailed syntactic representations as basis for extracting sentence meaning. These models share the assumption that the representations computed by the HPM accurately reflect the linguistic input. This assumption has been challenged…

Arabic grammar learning - which uses textbooks with lengthy details can be translated into creative and innovative forms through the application of technology advancement. Animated infographics is one of the many technological applications aimed to innovate learning information or content into simple, interesting, and easy to understand materials.…

This study examines the discourse basis for referent accessibility and its relation to the choice of referring expressions by children with Autism Spectrum Disorder (ASD) and typically developing children. The aim is to delineate how the linguistic and extra-linguistic context affects referent accessibility to the speaker. The study also examines…

Purpose: The current study takes a practical and theoretically grounded look at assessment of morphological knowledge and its potential to deepen understanding of how morphological knowledge supports reading comprehension for students with limited reading vocabulary. Specifically, we explore how different morphological skills support reading…

Introduction: Baddeley's model of working memory establishes the basis for identifying components that intervene in immediate repetition verbal tasks. Based on this model, the overall aim of the present study was to analyze the relationship between auditory sequential memory and verbal memory in students with intellectual disabilities and thereby…

Students are expected to comprehend and produce increasingly complex texts in upper elementary school, and academic language and literacy skills are considered critical to meeting these expectations. Notions of academic language are also controversial and require careful deliberation when applied to traditionally minoritized populations, including…

Learner corpus studies using syntactic complexity as a construct for characterizing learner proficiency have found that higher proficiency permits learners to produce more complex syntactic structures. However, the majority of previous studies have focused on writing, almost exclusively with adult second language (L2) learners. Given the…
