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.…

Linguistic encoding of spatial events has long provided a forum for examining how languages encode space, how children learn their native encodings, and whether cross-linguistic differences affect non-linguistic representations of space. One prominent case concerns motion events in which objects are moved into tight or loose-fit relationships of…

Iterated learning models of language evolution have typically been used to study the emergence of language, rather than historical language change. We use iterated learning models to investigate historical change in the accent classes of two Korean dialects. Simulations reveal that many of the patterns of historical change can be explained as…

There has been plenty of observational evidence displaying that L2 English learners whose L1 do not have article systems undergo persistent difficulties. It is known that functional categories of grammar are especially difficult for L2 learners, and the Korean language does not have a functional equivalent to English articles. The current study…

Evidence from life science, cognitive science, and philosophy supports the hypothesis that knowledge is a central norm of the human practice of assertion. However, to date, the experimental evidence supporting this hypothesis is limited to American anglophones. If the hypothesis is correct, then such findings will not be limited to one language or…

This dissertation examines the development of the internal structure of the Korean syllable by adult Korean learners whose native language is English. Prior research has identified the prominence of the body constituent in Korean and the rime constituent in English. The current study focuses on the acquisition of the body unit by English speakers…

While metadiscourse use has been well-attended in second language (L2) writing research, relatively less effort has been made in documenting changing patterns of metadiscourse use among L2 writers. The present study addressed this gap by probing a diachronic change of interactive metadiscourse in research articles published in "English…

Testing is increasingly recognized as a vital part of language revitalization. I demonstrate here that assessment of linguistic knowledge should also be part of the planning process that precedes the creation of a revitalization program. I take as an example Jejueo, the language of Korea's Jeju Island. Whereas previously published work…

This study has two goals. First, we present much-needed empirical linguistic data and systematic analyses on the spatial semantic systems in English and Korean, two languages that have been extensively compared to date in the debate on spatial language and spatial cognition. We conduct our linguistic investigation comprehensively, encompassing the…

This study examined how students of English as a foreign language (EFL) with different first language (L1) backgrounds use interactional metadiscourse markers in argumentative writing. Specifically, to explore unique patterns of metadiscourse features that reflect context and development, the essays written by Chinese, Japanese, and Korean EFL…

To avoid potential miscommunication resulting from structural ambiguity, speakers and listeners often rely on differences in prosodic realization. For instance, the sentence "Jennifer blackmailed the boss of the clerk [who was dishonest"][subscript RC'] is realized with different prosody depending on the attachment of the relative clause…

Research attempting to understand the intermediate stages of first-language acquisition and disordered speech has led to the discovery of covert contrast. A covert contrast is a statistically reliable difference between phonemes that is produced by a language learner, but in a way that cannot be heard readily by a listener of the target language.…

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 study investigates the second language (L2) acquisition of the English count/mass distinction by speakers of Korean and Mandarin Chinese, with a focus on the semantics of atomicity. It is hypothesized that L1-Korean and L1-Mandarin L2-English learners are influenced by atomicity in the use of the count/mass morphosyntax in English. This…

This study presents an experiment that explores the patterns of answers to yes-no truth-functional questions in English and Korean. The answering patterns are examined from 12 Korean-English bilingual children and 10 Korean-monolingual children. Four types of sentences in relation to given situations (Wason in "Br J Psychol" 52:133-142,…
