Due to the typological differences between Korean's aspect system and English's aspect system in terms of progressive construction "-ko iss," learners can no doubt have difficulty acquiring and using the "-ko iss" construction in learner Korean. This dissertation investigates two main points: (i) how is the "-ko iss"…

Lexical inference through reading is considered an important method for vocabulary building; however, empirical research has not consistently offered strong evidence of the application of lexical inference in second language vocabulary learning. A recently burgeoning line of research focuses on second language (L2) lexical inference of compounds…

This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…

Past experimental studies of corrective feedback (CF) have isolated factors like grammatical complexity, learner proficiency, and L1 one by one, carefully designing experiments that eliminate the influence of "extraneous" factors. Because each factor is actually codependent, more holistic study is needed. Eleven studies, all of which had…

We present a proof-of-concept study that sketches the use of compression algorithms to assess Kolmogorov complexity, which is a text-based, quantitative, holistic, and global measure of structural surface redundancy. Kolmogorov complexity has been used to explore cross-linguistic complexity variation in linguistic typology research, but we are the…

This study aims to examine the relationship between bilingual experience and children's development of morphological and morpho-syntactic awareness. To capture both universal and language-specific bilingual effects, the study included four groups of participants: English-speaking children from a general education programme, Spanish-speaking and…
