In this dissertation, I establish a research program that uses computational modeling as a testbed for theories of phonological learning. This dissertation focuses on a fundamental question: how do children acquire sound patterns from noisy, real-world data, especially in the presence of lexical exceptions that defy regular patterns? For instance,…

This dissertation explores first language (L1) transfer and second language (L2) transfer processes and models, such as the full transfer/full access model (FT/FA), the representational deficit/interpretability hypothesis, and the feature reassembly hypothesis (FRH). The typological proximity model (TPM), the cumulative enhancement model (CEM),…

This dissertation investigates the morphological and morphosyntactic processing of case-marking by native and nonnative speakers of Turkish, through behavioral and electrophysiological responses. The study explores the locus of case processing costs during first (L1) and second language (L2) word recognition both in isolation and in sentences. It…

This dissertation examines primarily the syntactic, but also the semantic/pragmatic behavior of sentential complement clauses in Turkish and proposes a new classification of such complements. A head-final language, Turkish lacks an overt, lexical complementizer akin to English "that". The most frequent types of sentential complementation…

This study discusses the relationship between Taiwanese adult learners' identity development and language curriculum, exploring how students (re)constructed their identities within the Taiwanese social context. Influenced by exam culture and educational credentialism, Taiwanese language education is mainly exam-oriented and teacher-centered.…

This dissertation examines the question of how phonological alternations are learnt. In constraint-based models of phonological learning, it is hypothesized that prior learning of phonotactics from the lexicon facilitates the learning of alternations. While this is an influential assumption, the empirical evidence for it is equivocal. In this…

This dissertation outlines a program for the theory of phonotactics--the theory of speakers' knowledge of possible and impossible (or likely and unlikely) words--and argues that the alternative view of phonotactics as stochastic, and of phonotactic learning as probabilistic inference, is not capable of accounting for the facts of this domain.…

This dissertation is an analysis of the morphosyntax of the Turkish causative construction within the framework of Distributed Morphology (DM). It is an attempt to capture a range of different phenomena in a principled way within this framework. Important aspects of DM for the analysis herein include the syntactic derivation of words; the…

This dissertation concerns the acquisition of the interaction between lexicosemantic properties of verbs and syntax, focusing on symmetrical and asymmetrical verbs in different syntactic structures. Based on linguistic evidence, it is shown that two conceptual categories, Mutuality and Number, interact to give rise to four event-types: Single…

This dissertation is an analysis of two types of nominal compounds in Turkish, primary compounds and synthetic compounds within the framework of Distributed Morphology. A nominal primary compound is formed by two nouns, and its meaning is largely determined by world knowledge. A synthetic compound, on the other hand, is formed by a noun and a…

This dissertation examines the syntactic positions of nominal arguments in Turkish, looking at Turkish clausal structure based on Aktionsart (aspectual) properties (e.g. Vendler 1967) of (dynamic) predicates from the perspective of Antisymmetry (Kayne 1994). It has been argued that indefinite/non-specific arguments appear syntactically in lower…

Language modeling is one of many problems in language processing that have to grapple with naturally high ambient dimensions. Even in large datasets, the number of unseen sequences is overwhelmingly larger than the number of observed ones, posing clear challenges for estimation. Although existing methods for building smooth language models tend to…

This dissertation contains three studies that investigate whether attested patterns of constituent order distribution and change in the world's languages can be attributed, in part, to cognitive preferences for some constituent orders over others. To assess these preferences, seven experiments employed an "elicited pantomime" task.…

The goal of this dissertation is to investigate the nature of word order variation in declarative and interrogative clauses in Turkish within the framework of the generative syntax. The specific issue that will be examined in this dissertation concerns the role of discourse-pragmatics in word order variation. I will argue that all movement…

This dissertation explores the incorporation of Facebook into everyday live activities and practices of a group of young Turkish-American women affiliated with a faith-based movement, known as the "Hizmet" (volunteer's service) movement. In particular, I examine the emergent communicative practices and performances of these young…
