In a body of empirical research, it has been observed that young children from across different linguistic communities adhered to a particular type of nonadult interpretation of disjunction: They appear to interpret disjunction conjunctively. Through three experiments with Japanese-speaking preschoolers, we investigate the source of this nonadult…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

This study investigated the relative contributions of English morphological and vocabulary knowledge to second language (L2) reading comprehension among 100 adult Japanese English as a foreign language (EFL) learners. The study also investigated the extent to which the roles of morphological and vocabulary knowledge in L2 reading comprehension…

Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…

Children acquire argument structure through distributional evidence, but how does this interacts with event semantics and existing verb knowledge? The current study compares verb learning in adult speakers of Japanese (where lexical causatives span wider semantic categories) and English (where alternation is more restricted). In the Fully…

Various explanations have been put forth for the asymmetrical acquisition of tense and aspect morphology across categories of lexical aspect. This experiment tested the adequacy of a subset of such accounts by examining English native speakers' (n = 40) use of progressive and past tense morphology within activity and accomplishment verb frames…

For many sociolinguists, the issue of shyness and hesitation phenomenon has been problematic for Japanese L1 and L2 speakers, particularly in gendered interactions. Over the past decade, more Japanese are shunning conversations, relationships, and isolating themselves, which is accelerating the demographic crisis in Japan. Thus, this paper focuses…

The present study examined the use of prosody in semantic and syntactic disambiguation by means of comparison between Japanese and Chinese speakers' production of English sentences. In Chinese and Japanese, lexical prosody is more prominent than sentence prosody, and the sentential meaning contrast is usually realized through particles or a change…

Corpus linguistics identifies the qualitative difference in the characteristics of spoken discourse vs. written academic discourse. Whereas spoken discourse makes greater use of finite dependent clauses functioning as constituents in other clauses, written academic discourse incorporates noun phrase constituents and complex phrases. This claim can…

While L1 transfer and L2 learnability have been studied extensively in the domain of syntax and the syntax/semantics interface, purely semantic phenomena have received little attention in the L2 literature. This paper presents two experiments examining the relative scope assigned to disjunction and negation by English-speaking learners of Japanese…

This article discusses the effects of repetition (1, 3, 7, and 10 encounters) on word knowledge in a carefully controlled study of 121 Japanese students learning English. The study is innovative and original in several aspects. (1) The study uses 10 tests to measure knowledge of orthography, association, grammatical functions, syntax, and meaning…

This dissertation reports development and validation studies of a Web-based standardized test of Japanese as a foreign language (JFL), designed to measure learners' off-line grammatical and pragmatic knowledge in multiple-choice format. Targeting Japanese majors in the U.S. universities and colleges, the test is designed to explore possible…

The study reported in this article is a part of a large-scale study investigating syntactic complexity in second language (L2) oral data in commonly taught foreign languages (English, German, Japanese, and Spanish; Ortega, Iwashita, Rabie, & Norris, in preparation). In this article, preliminary findings of the analysis of the Japanese data are…

Investigated whether syntactic computation takes place in an ambiguous sentence fragment in Japanese and if and how information from constituents other than the verb is utilized. Experiments were conducted using automated, word-by-word visual presentations with a lexical decision task on an extrasentential target. (Author/VWL)

Analyzes data from oral interviews with child learners of Japanese as a second language. Findings indicate that: tasks sensitive to students' understanding of critical syntactic structures and manageable for their cognitive level were effective; high-level students tried to produce more Japanese with more complexity; and phrase particle use was…
