All communication systems rely on sets of rules that must generally be followed for successful communication to be possible; in the case of human language, these rules are given by the grammar. However, despite these rules, there is considerable variation that has been noted across the grammar. In this dissertation, I explore one understudied…

In two visual world eye-tracking experiments, this dissertation examines the role of literacy on predictive processing during spoken language comprehension. Previous studies have shown that comprehenders can use morphosyntactic cues available in the input to generate predictions about upcoming information. Recent key findings also suggest that…

The system of second person singular forms of address (2PS) in Medellín, Colombia is tripartite consisting of "tú, vos," and "usted," while also including the existence of a dual "usted." The current study compares usage of the intimate "usted" versus the distant "usted" with data from an oral…

Given that project-based learning (PjBL) allows for hands-on application in realistic contexts and that immersive virtual reality (iVR) allows learners to interact with multiple modalities of information and immerse in a real-world English environment, this study investigates how incorporating iVR technology into PjBL contexts affects students'…

An extensive number of corrective feedback (CF) studies have examined learners' errors with grammar, vocabulary, pronunciation, and spelling (non-formulaic forms) and established an association between learners' uptake of CF and their second language development. However, learners' errors with formulaic sequences (FSs) comprising idioms,…

The development of 4- to 6-year-olds' narrative skills was investigated in relation to their receptive vocabulary, grammar, and home literacy environment. At Time One, 82 children aged 4 to 6 years completed standardised assessments of cognitive ability, vocabulary, and grammar. Narrative production and comprehension were assessed by the narration…

We investigated the acquisition of Hindi split ergativity (zero or "-ne" marking) and Hindi differential object marking (DOM; zero or "-ko" marking) by L1 speakers of Dutch. Both grammatical phenomena are conditioned by multiple syntactic and semantic features. On a descriptive level, the study aims to examine when and how…

The current study examines the bilingual language development of twelve young children. We focus on the use of Spanish as a heritage language among the children while they learn English in an English-majority environment. Data was collected in English and Spanish four times over the first two years of formal schooling. The study focuses on oral…

Languages differ in their realization of the subject argument: non-null-subject languages, like English, require subjects to be phonologically overt; rather, null-subject languages, like Greek, allow the subject to be overt or null. This cross-linguistic difference can lead to the transfer of grammatical properties across languages during…

Purpose: This study investigated the effects of an AR application (Civilisations AR) on EFL learners' oral proficiency in the dimensions of content, fluency, vocabulary, pronunciation, and grammar, as well as their attitudes and perceptions toward AR technology. Design: Utilizing a quasi-experiment, twenty-four EFL learners engaged in a…

Fluency development is one of the prominent components of a well-balanced language course. In particular, speaking fluency interests second language (L2) researchers who have continuously tried to look for the finest approach for helping L2 learners attain a certain level of fluency to achieve effective communication. To this end, the primary…

The field of Heritage Language has experienced a great deal of advancement in the past few decades. Much research effort has been dedicated to analyzing and understanding different aspects of heritage language speakers, but less work has been done in the topic of pedagogical approaches. The few recent studies on pedagogical approaches have focused…

The study aims to determine whether exposing EFL Saudi undergraduate students to TED talks could effectively contribute to the improvement of their oral language proficiency. To achieve this goal, 32 English as a Foreign Language Saudi undergraduate students were recruited to participate in the study. These students were selected based on their…

Purpose: We investigated the efficacy of "Story Champs" for improving oral language in third-grade Spanish-English bilingual children with developmental language disorder (DLD). Method: We implemented a concurrent multiple-baseline across-participants single-case design with four bilingual Spanish-English third-grade students with DLD.…

This study investigated the effects of a reading assistant software on the fluency and accuracy of speech production among EFL university students, employing a one-group pretest-posttest design. The participants included 50 Thai undergraduate English majors in their first and second years. Data were analyzed using paired samples t-tests to measure…
