Segmentation is a cornerstone of language processing across levels of linguistic analysis, and yet, standard models of linguistic memory leave the role of higher-order segments in online comprehension understudied. This dissertation advances the Context-Sensitive Encoding (CSE) hypothesis: that implicit prosodic boundaries (Bader, 1998; J. Fodor,…

What makes some sentences more difficult to process, and why? Memory- and expectation-based theories both attempt to explain sentence processing difficulties, and decades of sentence processing literature have found evidence in support of both theories. This dissertation further investigates these theories of sentence processing by exploring…

Approximately 30% of individuals with autism have complex communication needs (CCN). These individuals are unable to use vocal speech as their primary form of language and typically require support across several areas of communication such as comprehension, pragmatics, phonology, semantics, and syntax (Ganz et al., 2022; Reichle, 2019).…

Given its complexity, abstractness, and central role in many logics, negation might be a conceptual accomplishment. Therefore, young children's gradual acquisition of negation words might be due to their undergoing a conceptual change that is necessary to represent logical meanings. However, it's also possible that expressing negation takes time…

Syntactic movement is central to mainstream generative theories of syntax (Chomsky, 1957; 1981; 1995; 2001). Under this view, sentences contain words that have moved and words that have not. Children only ever hear words in their moved positions so it is unclear how they could determine the ways these constituents must be merged and moved from…

Eventualities have been recognized as psychologically and linguistically relevant for more than 50 years. Psychologically, eventualities are complex bundles of information derived from our perceptions of the world. The question for linguists is how much of this complexity is reflected in our eventuality-denoting lexical entries and the…

Research in first-language (L1) sentence processing has found evidence that language comprehenders use binding condition A as a filter to rule out noun phrases that are binding-inaccessible before proceeding with the task of finding the correct antecedent. Sturt (2013) notes that this strategy does not appear to apply to advanced speakers of…

All communication systems rely on sets of rules that must generally be followed for successful communication to be possible; in the case of human language, these rules are given by the grammar. However, despite these rules, there is considerable variation that has been noted across the grammar. In this dissertation, I explore one understudied…

It is well known that persons with aphasia (PWA) demonstrate deficits in sentence processing. Specifically, many show difficulties with syntactic re-analysis, or the ability to revise one's interpretation of a sentence due to a temporary ambiguity. Emerging evidence suggests that structural priming, individuals' tendency to unconsciously re-use a…

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…

In everyday life, humans rely on working memory (WM) processes to make sense of relationships between linguistic elements that are not linearly adjacent. For example, to understand the sentence "The dog that the cat chased is cute," we encode the referent "the dog" into WM, maintain and retrieve it after reading the verb…

As humans, we use language with ease and speed, solving the complex computational problem of processing form and meaning seemingly without effort. This dissertation studies how the properties of language enable us to achieve this, by investigating what is computationally difficult about language, and what is easy. We first investigate the…

This dissertation explores the role of memory in language processing, and specifically how interference during lexical encoding can result in downstream interference during retrieval. The dissertation merges insights from both the sentence processing literature as well as the study of memory in non-sentential contexts and focuses on two factors…

F0 contours convey multiple types of information, including lexical and post-lexical meanings, as well as affective and socio-indexical indicators. This dissertation investigates the interaction between lexical tone and sentence-level intonation in Thai, focusing on how sentence position influences the acoustic realization and perceptual…

Comprehenders encounter a variety of syntactic structures through reading or spoken conversation. In some cases, sentences can be ambiguous and have more than one meaning. In "The spy saw the cop with the binoculars," one interpretation is that the spy is looking through the binoculars, while an alternative is that the cop has the…
