Language disorder is characterized by difficulty with the comprehension and production of different aspects of language. School-aged children with developmental language disorder (DLD) and school-aged children with Down syndrome (DS) demonstrate similar deficits in the area of morphosyntax, which often creates barriers during social interactions…

The digital transformation in educational assessment has led to the proliferation of large-scale data, offering unprecedented opportunities to enhance language learning, and testing through machine learning (ML) techniques. Drawing on the extensive data generated by online English language assessments, this dissertation investigates the efficacy…

Prior research has extensively explored audiovisual speech perception and literacy skills in various linguistic contexts. Studies have shown that children's ability to integrate auditory and visual speech cues plays a crucial role in language acquisition and development (Erdener & Burnham, 2013; Lalonde & Werner, 2021). Furthermore,…

Language is one of the hallmarks of intelligence, demanding explanation in a theory of human cognition. However, language presents unique practical challenges for quantitative empirical research, making many linguistic theories difficult to test at naturalistic scales. Artificial neural network language models (LMs) provide a new tool for studying…

This predictive correlational study explored the lack of generalizable data regarding the use of technology in the Christian K-12 environment. The study searched for a predictive correlation between teachers' overall use of technology, openness to change, amount of technology training, and hours of work beyond the contractual work week, based on…

This dissertation presents a formal theory of Serbo-Croatian grammar. The theory predicts acceptable form/meaning pairs for a substantial chunk of Serbo-Croatian. In particular, we analyze Serbo-Croatian declarative and interrogative main clauses, embedded clauses, a couple of different types of nominal modification, control and predication, as…

Landau (2000) distinguishes between P(artial) C(ontrol) and E(xhaustive) C(ontrol): PC predicates like hope admit a subset relation between controller and controllee (e.g., "Kim hoped to gather at noon." [controllee = Kim and contextually salient others]); EC predicates like "try" do not (*"Kim tried to gather at…

This dissertation investigates how knowledge of phonological generalizations influences speech perception, with a particular focus on evidence that phonological processing is autonomous from (rather than interactive with) auditory processing. A model is proposed in which auditory cue constraints and markedness constraints interact to determine a…

This dissertation will focus on the processing and learning of abstract, phrasal argument structure constructions. Chapter 1 provides the theoretical framework for abstract constructions, and illustrates the importance of such representations in speakers' linguistic knowledge. Chapter 2 reviews the evidence for meaning being associated with…

This dissertation contains several projects, each addressing different questions with different techniques. In chapter 1, I argue that they are unified thematically by their goal of "scaling up psycholinguistics"; they are all aimed at analyzing large data-sets using tools that reveal patterns to propose and test mechanism-neutral hypotheses about…

Psychoeducational assessment, and specifically cognitive testing, is important to the role of school psychologists; however, the utility of such testing has been called into question, and its future is unclear. Researchers are divided into two camps. One side grew disenchanted with cognitive testing after the failure of the discrepancy method to…
