This dissertation developed a new learner corpus of Japanese and introduced an error and linguistic annotation scheme specifically designed for Japanese particles. The corpus contains texts written by learners who are in the first year to fourth year university level Japanese courses. The texts in the corpus were tagged with part-of-speech and…

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…

While acquiring a second language, learners may encounter challenges and difficulties in effectively carrying out verbal communication in the second language. Mastering the apology speech act is a challenge for L2 learners. The objective of this study is to identify the apology strategies utilized by individuals learning the Japanese language, as…

Laufer (1988) introduced the concept of synform errors, where second language (L2) learners confuse a word for a different but similar looking or sounding L2 word. Stubbe and Cochrane (2016) reported that of 1,187 commonly repeated errors on a Japanese to English non-contextual translation test, 461 were synform errors (39%). This study introduces…

This study focused on the grammatical accuracy of Japanese students who were learning English. The database for the errors came from the Japanese University Student Corpus (JUSC) comprising 61 transcripts containing 51,061 words. An inventory, containing 400 errors in context, was taken from this corpus. The first research question related to the…

This article contends that the profile of a foreign language learner can contain valuable information about possible problems they will face during the learning process, and could be used to help personalize feedback. A particularly important attribute of a foreign language learner is their native language background as it defines their known…

This article studies the use of support verb constructions (SVCs) in the written production of learners of Spanish. SVCs are lexical combinations whose content is similar to verbal predicates but is distributed between a verb and a noun, the noun being the carrier of the core lexical meaning of the predicate. Although there is considerable…

The study anchors on the Linguistic research tradition of Error Analysis (EA), focused on the grammatical errors, specifically on "verb tenses" manifested in the sentences of Japanese ESL learners. The entire respondent population was drawn from the pool of registered learners in 2017 at the Clark Institute of the Philippines Foundation,…

A list number recall test in English (L2) was administered to both Japanese (L1) students with beginning-level English proficiency who attended evening high school and Japanese college students with intermediate-level English proficiency. The major findings were that, only for the high school group, the small numbers 1 and 2 in middle positions of…

This paper presents a teacher-led inquiry into learner language awareness and learner perceptions of: oral presentations using first language (L1) support when using a second language (L2); and L2 learner and user identity. The quantitative-based results of this preliminary inquiry represent a source of understanding for the researcher, who later,…

This dissertation explores the second language acquisition of Mandarin Chinese tones by speakers of non-tonal languages within the framework of Optimality Theory. The effects of three L1s are analyzed: American English, a stress-accent language; Tokyo Japanese, a lexical pitch accent language; and Seoul Korean, a non-stress and non-pitch accent…

The focus of this dissertation is on how language experience shapes perception of a non-native prosodic contrast. In Tokyo Japanese, fundamental frequency (F0) peak and fall are acoustic cues to lexically contrastive pitch patterns, in which a word may be accented on a particular syllable or unaccented (e.g., "tsuru" "a crane", "tsuru" "a vine",…

This study compares second-year Japanese university students' strategies to write kanji by hand with their strategies to produce the kanji characters on a computer, taking into account factors such as accuracy in writing, the amount of kanji used, the complexity of the kanji used, as well as how the characters used compare with the sequence…

This study investigated first language (L1) influence on the acquisition of second language (L2) collocations using a framework based on Kroll and Stewart (1994) and Jiang (2000), by comparing the performance on a phrase-acceptability judgment task among native speakers of English, Japanese English as a second language (ESL) users, and Japanese…

This paper presents a new version of Robo-Sensei's NLP (Natural Language Processing) system which updates the version currently available as the software package "ROBO-SENSEI: Personal Japanese Tutor" (Nagata, 2004). Robo-Sensei's NLP system includes a lexicon, a morphological generator, a word segmentor, a morphological parser, a syntactic…
