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…

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…

Hidden structure refers to the units of organization that a child cannot directly observe when they are learning language (e.g. phonemes, morpheme boundaries, URs, phrases). In this dissertation, I propose a novel computational model that learns hidden structures in-tandem with the grammar. My model consists of two Maximum Entropy sub-models that…

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…

This dissertation investigates the extent to which bilingual speakers' cognitive representations of the syntactic structures of their two languages are interconnected. This is a substantially understudied domain despite the widespread existence of bilingual/multilingual communities in the world, including the US. To draw solid conclusions about…

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…

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.…

Over a century ago, rhetoricians called on writing instructors in the U.S. to accept and even encourage language diversity among learners. Yet scholars of composition, rhetoric, and writing studies are still advocating for this via arguments for linguistic justice and translingualism, even referring to strict adherence to a single, mainstream…

This dissertation investigates the syntax of case(-value)-assignment ([kappa]-ASSIGNMENT) and Phi(-feature)-agreement ([phi]-AGREEMENT) in nominal and verbal domains, with an emphasis on nomino-verbal infinitives and their cross-clausal dependencies, examining Kashmiri before extending to Hungarian. Although unrelated, both languages exhibit…

Background: The most common cause of aphasia is a left middle cerebral artery stroke affecting the left perisylvian region of the brain. The perisylvian region is critical for supporting phonological processing, and damage to this region results in difficulty with retrieving and manipulating speech sounds. The impact of weakened phonology has been…

The present study examined the acquisition of Spanish grammatical gender in 22 bilingual children (aged 5;0 to 13;5 years; Med=9;4 years; STD=2.3) who were born and raised in the United States and acquired Spanish as heritage speakers--that is, they learned Spanish, the minority language, in a home setting (Valdes, 2001). Each of the child…

Paradigms with conflicting data patterns can be difficult to learn, resulting in acquisition error. In this dissertation, I look at how paradigms are reanalyzed over time to gain insight into the factors that influence morphophonological learning. Existing models of morphophonology (e.g. Hare & Elman 1995; Albright 2002b,a, 2010) predict…

This experimental study investigated the impact of explicit and implicit feedback on acquiring Arabic grammar for second learners. The participants were forty-five lower-intermediate male participants studying Arabic as a second language in a Saudi Arabian language institution. All participants were equally divided into three groups; the explicit…
