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…

This paper examined whether a younger starting age of formal instruction on a foreign language is beneficial in expanding circle countries. An experimental study was designed to examine to what extent the five varieties of English language teachers are intelligible to Japanese- (JSLs) and Korean-speaking language learners (KSLs), who have…

This study investigated the effects of explicit and implicit discourse marker (DM) instruction on English as a foreign language (EFL) learners' speech. Two different teaching methods were used over seven weeks of online English classes at a university in Japan. Participants were split into two groups, and in the first week, a pre-test comprising…

One way that language educators can extend a role-play is by adding a complication to encourage the learner say more. This study uses multimodal conversation analysis to explore such obstacles to progressivity among Japanese learners of English at an experiential language learning facility. We first examine an interactional practice in which the…

Purpose: Understanding what is known about the language profiles of children with hearing loss (CHL) is vital so that researchers and teachers can identify the specific complex syntactic structures that CHL may struggle to master. An understanding of which aspects of complex syntax pose difficulties for CHL is necessary to inform the kind of…

The present study attempts to identify difficulties that Japanese students encounter with metadiscursive nouns in writing second language (L2) argumentation essays. Metadiscursive nouns are abstract and unspecific nouns which can serve as cohesive markers by retrieving their meanings in the text where they occur. Using a selected number of nouns…

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…

Prior research showed that interleaved practice (studying multiple skills at once) is more effective than blocked practice (studying only one skill at a time). This study aims to replicate the benefits of interleaved practice on the proceduralization of second language (L2) syntax and further examines the role of working memory (WM) in different…

The present study investigated the impact of chunk reading training (CRT) on the online syntactic processing and verbal working memory (WM) of Japanese EFL (English as a foreign language) learners in secondary school. For four weeks, the treatment group (N = 31) underwent CRT, while the control group (N = 25) participated in reading training in…

This study reports on how project-based language learning in which L1 Japanese EFL learners created short videos affected L2 oral proficiency. Students took short speaking tests before and after the class, and the fluency, complexity and accuracy of the pre- and posttests were measured to see which, if any, of these three aspects of proficiency…

This article updates the trends and developments of Japanese as a second language (JSL) research since Mori and Mori (2011) by reviewing nearly 200 selected empirical studies published in English or Japanese between 2010 and early 2019. The first section of this review examines the cognitive aspects of second language (L2) Japanese development,…

The Interface Hypothesis (Sorace, 2000) developed in line with the Minimalist theory of grammar (Chomsky, 1995 et seq.) supports the view of L2 acquisition that syntactic properties are acquired early while the acquisition of interface properties is delayed. One of the interface properties is inflectional morphology on English verbs, which…

When a newsmaker (i.e., a newsworthy subject) is speaking or being spoken about in a foreign language, quoting requires translation. In such "translingual quoting" (Haapanen, 2017), it is not only the content of the speech but also its translatability that determines newsworthiness. While news media in some countries prefer indirect…

This report describes the development of efficient second language (L2) writing assessment tasks designed specifically for low-proficiency learners of English to be included in the "TOEFL® Essentials"™ test. Based on the can-do descriptors of the Common European Framework of Reference for Languages for the A1 through B1 levels of…
