Phrasal verbs (PVs), comprising a lexical verb and an adverbial particle, are a notoriously difficult category of multiword units even for advanced learners of English because of their syntactic peculiarity and semantic complexity. Non-native professional interpreters have also been found to use PVs much less often than their native counterparts…

Inaudible syntactic markers are especially difficult to spell. This paper examines how 455 fourth graders spell silent French plural markers in a dictation with real and pseudowords after one year of formal French instruction (L2). The Generalized Linear Mixed Model analysis shows first that noun plural spelling (real and pseudo) is a strong…

In this study, I investigated the simultaneous effects of the reader, the text, and the task factors, and their interactions, on reading comprehension, using explanatory item response models. Analyses of a large data set from a commercially available online assessment system with a wide range of readers (n = 10,547) and passages (n = 48) uncovered…

Multi-word expressions are formulaic language universals with arbitrary and idiosyncratic collocations. Their usage and mastery are required of learners of a second language in achieving naturalness. However, despite the importance of multi-word expressions to mastering a second language, their syntactic architecture and colligational…

Texts classified according to guided reading levels (GRL) are ubiquitous in US beginning reading classrooms. This study examined features of texts across three grade bands (kindergarten, early first grade, final first grade) and the 10 GRLs within these bands. The 510 texts came from three programs with different functions in beginning reading…

Lexical bundles (LBs) are frequent groups of words that appear repeatedly in different academic texts. A plethora of research has explored their distribution and usage in general, particularly in academic texts. However, to our knowledge, the extent of research investigating LBs in the discussion sections of Medical Research Articles (MRAs) is…

Purpose: This study sought to 1) identify linguistic features important for Chinese text complexity with a theory-based and systematic approach, and 2) address how feature sets and algorithms affect the performance of Chinese text complexity models. Method: Texts from Chinese language arts textbooks from Grades 1 to 6 (N = 1,478) in Mainland China…

A central concern of the cognitive science of language since its origins has been the concept of the linguistic system. Recent approaches to the system concept in language point to the exceedingly complex relations that hold between many kinds of interdependent systems, but it can be difficult to know how to proceed when "everything is…

Students with high reading proficiency typically achieve better results in science assessments, indicating the importance of reading proficiency. Since the process of reading is a complex interaction between properties of a text and a reader, the linguistic demands of a text might affect text comprehension. Certain linguistic features, such as…

Evaluating creativity of verbal responses or texts is a challenging task due to psychometric issues associated with subjective ratings and the peculiarities of textual data. We explore an approach to objectively assess the creativity of responses in a sentence generation task to (1) better understand what language-related aspects are valued by…

Purpose: The graphic symbol is the foundation of augmentative and alternative communication (AAC) for many preliterate individuals; however, research has focused primarily on static graphic symbol sequences despite mainstream commercial technologies such as animation. The goal of this study was to compare static and animated symbol sequences…

Comparing language tests and test preparation materials holds important implications for the latter's validity and reliability. However, not enough studies compare such materials across a wide range of indices. Therefore, this study investigated the text complexity of IELTS academic reading tests (IRT) and IELTS reading practice tests (IRPrT).…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

This study describes academic literacy development during mid-adolescence, when learners need to adjust to the demands of academic discourse as a gateway to linguistic adulthood. Unlike most research to date, which is cross-sectional and detached from disciplinary content, this study provides a two-year longitudinal description of academic…

When learning a language, typically-developing infants face the daunting task of learning both the sounds and the meanings of words. In this dissertation, we focus on a source of variability that complicates the one-to-one relationship between words and their meanings: wordform variability. In Chapter 1 we make a distinction between the micro…
