Sentence comprehension requires both syntactic prediction and working memory processes. Evidence suggests that both are impaired in agrammatic aphasia, and can independently contribute to comprehension breakdowns, but the relationship between them, especially during real-time sentence comprehension remains unclear. Two EEG studies investigated…

This dissertation investigates the nature of the interface between morphosyntax and cognition. My goal is to connect formal semantic theories of meaning with theories of cognition, drawing on the initial hypothesis that the interface between language and cognition is transparent. I look at different forms of adjectival comparatives -- positive and…

Due in part to its complex nature, there is still much to uncover in the investigation of the neural processes that contribute to synchronization between speakers and listeners during communication in the context of social cognition, specifically between native and nonnative English speakers and listeners. This study used a novel method of…

This dissertation explores how items encountered in the comprehension of language are stored in memory and subsequently accessed. Processing and comprehending language frequently requires the retrieval of items in memory so that a current linguistic element can be assigned an interpretation. For example, in a sentence such as "Miles loved his…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

This study investigates the relationship between three linguistic functions: thetics, miratives and exclamatives. Thetics are an information structure configuration that conveys that the information is new to the addressee. The thetic subtypes selected for this study are the following: existentials (e.g. "There are apples in the…

This dissertation focuses on when and how children learn about the meanings of the propositional attitude" verbs know" and "think". "Know" and "think" both express belief. But they differ in their veridicality: "think" is non-veridical and can report a false belief; but "know" can only…

Modern intelligent agents will need to learn the actions that humans perform. They will need to recognize these actions when they see them and they will need to perform these actions themselves. We want to propose a cognitive system that interprets human manipulation actions from perceptual information (image and depth data) and consists of…

Narrative has been formally studied for at least two millennia, dating back to the writings of Aristotle. While most theories began by describing the construction of plotlines in theatre, most contemporary research on the structure and comprehension of narratives has examined the discourse of spoken language. However, visual narratives in the form…

This research examines advertising discourse in Russian and English as acts of communicative exchange and interpersonal relationship between advertising discourse participants. The purpose was to identify and describe the way that viewers process information contained in television commercials and how they become consumers moving from getting…

While normal child language acquisition results in complete productive and comprehension abilities at a relatively young age, adult language acquisition is more belabored and often results in linguistic abilities that differ from those of native speakers in terms of both productive and comprehension abilities. A major line of research in language…

Recasts are one type of corrective feedback that reformulates all or part of a learner's erroneous utterance during communicative interaction without changing the meaning. Categorized as implicit and input-providing corrective feedback, recasts have become the focus of debate in the area of interaction research in recent years. The debate…

The purpose of this dissertation is to investigate the processing mechanisms of non-native English speakers at both the sentence level and the morphological level, addressing the issue of whether adult second language (L2) learners qualitatively differ from native speakers in processing linguistic input. Using psycholinguistic on-line techniques…

A basic challenge for research into the neurobiology of language is understanding how the brain combines words to make complex representations. Linguistic theory divides this task into several computations including syntactic structure building and semantic composition. The close relationship between these computations, however, poses a strong…

The purpose of this research is to describe and understand the ways in which deaf middle school students understood and solved compare word problems, and to examine their overall strategy use in learning mathematics. The participants in the study were deaf middle school students, attending a residential state school for the deaf. Most of them used…
