Purpose: This study focuses on examining how individual differences, including biological, linguistic, and cognitive traits, and prosodic focus affect the computation biases and reaction time (RT) associated with quantity scalar terms in Mandarin-speaking children aged 3-8 years. Method: The participants of this study were 27 Mandarin-speaking…

The comprehension of connectives is crucial for understanding the discourse relations that make up a text. We studied connective comprehension in English to investigate whether adult comprehenders acquire the meaning and intended use of connectives to a similar extent and how connective features and individual differences impact connective…

Individual speakers' speech patterns differ from one another, despite presumably similar language input. What are the sources of this individual variability? In this dissertation, I explore sources of individual differences in pronunciation of coronal obstruents (/s/, /t[superscript h]/, /c[superscript h]/, /c/) at the ends of nouns in Korean.…

This study investigates how individual-level factors contribute to classroom engagement variations of boys and girls across the elementary school years. Classroom engagement was assessed four times between the ages of 7 and 12 years in a large, representative population-based sample (N = 877) using latent growth modeling. Predictors included the…

This sequential mixed-method study aimed to explore elementary reading teachers' perceptions and experiences of vocabulary practice and student self-efficacy to increase reading achievement. The quantitative approach utilized a Likert-type survey design shared with respondents through email to identify teachers' perceptions of vocabulary…

Bilingual children often lag behind monolinguals on standardized measures of language acquisition, such as vocabulary tests. This bilingual lag could be related bilinguals' lesser experience with the target language relative to monolinguals. In this study, we predicted that sequential Mandarin-English bilinguals would perform worse than same-aged…

There is a need for a continued focus on language learning in advanced language classes beyond the foundations that are formed in the beginning and intermediate levels. Despite this need, little work exists on how to implement language-focused instruction in upper-level courses. As one possible solution, this paper outlines a functional,…

Background: We examined the influence of text and reader characteristics on sixth graders' inference generation. Methods: Eleven- to 12-year-old US monolingual English speakers (N = 71) and Spanish-English bilinguals (N = 81) read narrative and informational expository texts requiring an inference and answered an inference-tapping question after…

Background & aims: There is increasing recognition of the importance of challenging deficit-focused, medical model approaches to supporting autistic people in daily life, however there is a lack of inclusion of autistic perspectives to inform approaches that may empower autistic people in conversations. Methods: This multiple case study used a…

Sentence production and comprehension both draw on linguistic knowledge, but current research is unclear on whether these fundamental language tasks involve similar or distinct competitive processes. Previous studies suggest that production and comprehension may involve similar conflict resolution processes, but that production may additionally…

Few studies have explored how general skills in both reading and writing influence performance on integrated, source-based writing. The goal of the present study was to consider the relative contributions of reading and writing ability on multiple-document integrative reading and writing tasks. Students in the U.S. (n=94) completed two tasks in…

The undeniable importance of reading in higher education prompted this investigation into the reading skills of a group often overlooked in previous research: master's level students studying in English-medium instruction (EMI) environments. Participants (148 master's-level students of engineering) completed the Nelson-Denny Reading Test (Form G),…

Background: Speech in individuals with cleft lip and/or palate (CLP) is a complex myriad of presenting symptoms. It is uniquely associated with the structural difference of velopharyngeal insufficiency (VPI), together with a wide and heterogeneous range of other aetiologies which often co-occur. The nature of the speech sound disorder (SSD)…

Purpose: The probability of a child reading a word correctly is influenced by both child skills and properties of the word. The purpose of this study was to investigate child-level skills (set for variability and vocabulary), word-level properties (concreteness), word structure (mono- vs polymorphemic), and interactions between these properties…

This study investigates how task complexity affects native speakers' and second language (L2) learners', and experts' perceptions of task difficulty in writing tasks. It also explores how task complexity influences English native speakers' and L2 learners' linguistic complexity in their writing. Ninety participants performed one simple and one…
