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.…

Research on second language (L2) pronunciation self-assessment reports a general misalignment between self- and other-assessment. This has been attributed to the object of self-assessment, the self-assessment task, the measures to which self-assessment is compared, and speakers' characteristics. Here, we examined self-assessment of a discrete…

This study aims to advance our understanding of the nature and source(s) of individual differences in pragmatic language behavior over the adult lifespan. Across four story continuation experiments, we probed adults' (N = 496 participants, ages 18-82) choice of referential forms (i.e., names vs. pronouns to refer to the main character). Our…

Learning to read and spell involves learning about the written forms of words and how these are linked to language. Writing systems include formal patterns, which pertain to the appearance of written words, and functional patterns, which pertain to links between units of writing and units of language. We review the evidence that learners of a…

Evidence of sensitivity to graphotactic and morphological patterns in English spelling has been extensively examined in monolinguals. Comparatively few studies have examined bilinguals' sensitivity to spelling regularities. The present study compared late Chinese-English bilinguals and English monolinguals on their sensitivity to systematic…

This study examines Korean L2 learners' production of English phonological contrasts (e.g., consonant-final versus vowel-final forms) that are absent in their L1. Twenty university students divided into high- and low-proficiency groups participated in the study. Their productions were analyzed for segmental accuracy and error patterns. Results…

Referential expressions such as pronouns are frequently used in conversations, and native speakers seem to understand who these expressions refer to effortlessly. Although the process of pronoun resolution seems to be easy, interpretations of pronouns are dependent on various sources of information from the discourse including morphosyntax (e.g.,…
