Speakers display considerable variability in language use and representations: they may have different pronunciations of the same word, different intended meanings for the same phrases, and different sets of syntactic constraints in their internalized grammars. Comprehenders adapt to such variability by constantly updating their expectations for…

Construction Grammar has been a prominent framework in linguistic research for nearly three decades, attracting scholars from various disciplines, including language acquisition, corpus linguistics, and psycholinguistics. While considerable progress has been made in understanding the first language (L1) construction learning of various languages,…

There has been increasing L3 research on L3 transfer selectivity, especially concerning which factor triggers crosslinguistic influence during L3 acquisition. According to Slabakova's (2016) Scalpel Model, every linguistic property has distinct and unique input factors regarding L3 acquisition such as high/low frequency or positive/negative input.…

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…

Adult second language (L2) learners often experience difficulty with novel L2 phonological contrasts, limiting their ability to establish contrastive lexical representations of L2 words. It has been demonstrated that the availability of orthographic input (OI), and variables interacting with OI, can shape the inferences learners make about L2…

This study compares monolinguals and different kinds of bilinguals with respect to their knowledge of the type of lexical phenomenon known as collocation. Collocations are word combinations that speakers use recurrently, forming the basis of conventionalized lexical patterns that are shared by a linguistic community. Examples of collocations…

Second language (L2) learners of tone languages do not perceive and produce the different tones of the target language with equal ease. The most common explanation for these asymmetries is that acoustically salient tones are the easiest to learn. An alternative explanation is that tones are easiest to learn when they are highly frequent in the…

This dissertation presents an approach for a productive way forward in the study of language acquisition, sealing the rift between claims of an innate linguistic hypothesis space and powerful domain general statistical inference. This approach breaks language acquisition into its component parts, distinguishing the input in the environment from…

This study utilized a paired priming paradigm to examine the influence of input features on case assignment in typically developing English-speaking children. The Input Ambiguity Hypothesis (Pelham, 2011) was experimentally tested to help explain why children produce subject pronoun case errors. Analyses of third singular "-s" marking on…

This study contributes to current trends of heritage speaker (HS) acquisition research by examining the syntax of psych-predicates in HS Spanish. Broadly defined, psych-predicates communicate states of emotions (e.g., to love) and have traditionally been categorized as belonging to one of three classes: class I--"temere" "to…

The Pacific Coast Athabaskan (PCA) languages are part of the Athabaskan language family, one of the most geographically widespread in North America. Over a millennium ago Athabaskan-speaking groups migrated into northwestern California and southwestern Oregon from a northern point of origin several hundred miles away, but even after several…

This dissertation examines the process of acquisition of semantic classes of reflexive verbs (RVs) in Russian by L2 learners with a native language English. The purpose of this study is to bridge the gap between current linguistic knowledge and the pedagogical literature existing in English on reflexives in Russian. RVs are taught partially and…

The dissertation study aims to contribute mainly to the field of loanword phonology in general and particularly to Indonesian and its phonology that are rarely studied to date. The study investigates what consonantal and syllabic repair strategies are employed by Indonesian in adapting Arabic and Dutch loanwords, whether these adaptation…

This thesis has two broad goals. The first is to contribute to the study of Arabic phonology particularly syllable structure and syllabification. This will be achieved through examining phenomena related to syllable structure and syllabic weight such as syllabification, stress assignment, epenthesis, syncope, and sonority in three different…

Theories of language acquisition have highlighted the importance of adult speakers as active participants in children's language learning. However, in many communities children are reported to be rarely directly engaged by their caregivers. This raises the possibility that children in these communities learn language from observing 3 rd party…
