Prediction-based accounts of language acquisition have the potential to explain several different effects in child language acquisition and adult language processing. However, evidence regarding the developmental predictions of such accounts is mixed. Here, we consider several predictions of these accounts in two large-scale developmental studies…

Purpose: This study used structural equation modeling to investigate the dimensionality of language in Spanish-English bilingual kindergartners. Five theoretical models were compared, including (a) a unidimensional model; (b) a two-dimensional model by language (Spanish, English); (c) a three-dimensional model by domain of language (phonology,…

This dissertation investigates the extent to which bilingual speakers' cognitive representations of the syntactic structures of their two languages are interconnected. This is a substantially understudied domain despite the widespread existence of bilingual/multilingual communities in the world, including the US. To draw solid conclusions about…

This study investigated challenges that Saudi undergraduate learners face in translating oil contracts from English into Arabic. The study used a quantitative approach of data collection. The sample of this study consisted of 18 Saudi undergraduate learners of transaction departments at some Saudi universities. To achieve the objectives of this…

Based on the bilingual children's and adults' code-switching (CS) dependency treebanks, this paper investigates the syntactic features and pragmatic functions of the Chinese-English bilingual children's CS and compares them with bilingual adults'. It is mainly found that (1) As to the bilingual children, the mixed sentences present the longest…

Purpose: The current study examines bilingual children's development of Spanish and English morphosyntax structures over the period of 1 year. Identification of morphosyntax forms clustered by difficulty can elucidate their development and guide clinicians to select appropriate targets for intervention and monitoring. Specifically, we aim to…

We investigate sensitivity to island constraints in English native speakers and Najdi Arabic learners of English, examining (1) whether second language (L2) learners whose native language (L1) does not instantiate overt "wh"-movement are sensitive to island constraints and (2) the source of island effects. Under a grammatical account of…

This article offers a descriptive account of seven interjections, "eish", "yho", "tjo", "sho", "hayi", "hau", and "mxm", which are adopted from different local South African languages into South African English. It investigates the frequencies, orthography, syntactic position,…

In this dissertation I investigate the Mandarin "you"-existential sentence. My focus is on its syntax. I also discuss in less detail some semantic peculiarity of the "you"-existential. I begin my investigation of the syntax of "you"-existentials by first looking into what they are not. To this end, I present five…

This corpus-based multifactorial study delves deeper into the well-known alternation between bare and full infinitive complements, specifically regarding the "help" concordances. It extends the line of research to learners' language productions with a focus on comparing and contrasting the probabilistic grammatical knowledge reflected in…

This dissertation features a relative clause island, whose status has been known to differ significantly across languages and extraction types. By conducting a series of acceptability judgment experiments with human participants, as well as measuring token-by-token surprisal values among large language models, I demonstrate the following: First,…

Artificial Intelligence (AI) powered translation influxes in the translation industry. Yet, questions have arisen about the quality of AI-powered translation systems (AIPTSs). Therefore, this study aims to evaluate the translation quality generated by ChatGPT for the Farewell Sermon. Using House's (2015) model of translation quality assessment…

Bilinguals employ both global and local control mechanisms to manage coactivated languages that compete for selection, yet little is known about how they operate on morphosyntactic information. The current study investigated bilingual language control mechanisms for a morphosyntactic production task. Across two experiments, 48 early…

Understanding factors that influence reading achievement among bilingual children is considerably more complex than it is for monolingual children. Research on dual language development indicates that bilingual children's oral language abilities are often distributed across languages in varied ways, due to heterogeneity of dual language exposure…

Purpose: The purpose of this study is to examine the feasibility of the delivery of complex syntax recast therapy via telepractice to Spanish-English bilingual children and provide preliminary evidence of the efficacy of this approach. Method: Fifteen bilingual children with developmental language disorders were stratified based on language…
