The goal of this study is to contribute to the field of Japanese pedagogy by examining how Japanese native speakers and learners of Japanese as a foreign language with American cultural backgrounds take stances in discussions in Japanese. As stancetaking is a fundamental human behavior (Du Bois & Karkkainen, 2012; Iwasaki, 2015; Kiesling,…

Suprasegmental features (i.e., features realized through pitch, volume, and/or duration changes) are particularly difficult for second language learners. This has led to the creation of many different methods of training, often employing the use of experimenter or instructor-created training materials. However, the use of authentic materials for…

Recent advances in mobile technologies have prompted their investigation as tools for language learning. Mobile-assisted language learning (MALL) offers the advantage of flexible language support, enabling learners to choose when and where they learn and the methods that suit them. The constant connectivity of modern mobile phones allows learners…

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"…

This study examined the significance of the mode of delivery--aural versus written--in second language (L2) vocabulary knowledge and L2 comprehension skills.

Foreign language enrollments in U.S. higher education are falling at an unprecedented rate since the 1980s. This mixed methods case study sought to investigate this phenomenon by examining the motivational and attitudinal profiles of 89 beginning-level learners of foreign languages (Spanish, French, Arabic, Japanese) and the contextual factors…

The current study investigated the nature of second language (L2) learning influence on first language (L1) production and perception by systematically examining several L1 and L2 related factors (L1:L2 relative dominance, L2 production and perception acuity, and learning context) and their effect on L1 change. It is the first of its kind in…

When acquiring a second language, learners must become able to perceive the difference between novel sounds ("discrimination") and also associate strings of sounds with distinct vocabulary items ("lexical encoding"). Recent research has questioned whether discrimination is a sufficient or necessary condition for encoding, and…

This research is about the underlying process language learners rely on to be able to engage effectively in unscripted conversations without premeditation, or "improvisation." To engage in improvisation in another language, one needs to recognize those elements of the evolving cultural context that are significant at the moment. By…

The tendency for negation to appear early in the sentence, dubbed the "Neg-First principle" by Horn (1989:452), has been observed in the domains of typology, language contact, and language acquisition. Based on evidence from these fields, scholars have speculated about the source and universality of Neg-First biases affecting language…

At a time of heightened discourse on multilingual education in the United States, there is a need to question what is meant by the term and how its understandings may be perpetuating harmful power asymmetries. Specifically, California has declared its goal of supporting multilingual education from kindergarten through twelfth grade, yet the…

Professional training for language instructors needs to be more accessible and high-leverage in order to meet the growing demand for proficient users of Chinese, Korean, and Japanese languages. More specifically, teachers of these languages need exposure to effective teaching methods designed to meet the language-specific needs required to help…
