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,…

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).…

The sentence production system transforms preverbal messages in the mind of a speaker into coherent grammatical utterances. During this process, which unfolds rapidly, the system has to link meaning information from the speaker's message to appropriate lexical and grammatical information from the speaker's memory. It usually does so with fluency…

The current research investigates interactions between lexical and structural processing in the construction and interpretation of transitive and dative sentence structures, and relates speakers' choice of structure in sentence production to STM processes and recent/long-term language experience conditioned on lexical information. Study 1…

This work focuses on the licensing conditions and logical structure of understood-argument constructions, or complement-drop constructions, in English. There are two main types of such arguments: Indefinite Understood Arguments (IUA) and Definite Understood Arguments (DUA). IUA readings occur in such cases in "He ate, He cooked". In such cases,…

Research that examines diachronic change and modality posit that modal verbs follow certain universal paths of development (e.g. Cornillie, 2007; Bybee & Fleischman, 1995; Bybee, Perkins & Pagliuca, 1994). The present study examines the development of Spanish modality in Mexico through the use of multivariate analyses, relative…

This dissertation is a typological study of verb-final languages, the purpose of which is to examine various grammatical phenomena in verb-final languages to discover whether there are correlations between the final position of the verb and other aspects of grammar. It examines how finality of the verb interacts with argument coding in simple…

The scope of linguistic planning, or the amount of linguistic information that speakers can prepare in advance for an utterance they are about to produce, is highly variable. Distinguishing between possible sources of this variability provides a way to discriminate between accounts of language production that assume structurally incremental and…

Children use syntax as well as observations of events to learn verb meanings. This is known as syntactic bootstrapping. This dissertation investigated the origins and mechanisms of syntactic bootstrapping. Prior evidence suggested that two-year-olds, but not younger children, could use aspects of sentence structure to assign different…
