Natural language is known to play a crucial and specific role for children's learning in school mathematics. Not only does it carry special vocabulary, but subtle differences between natural languages may lead to surprising challenges, for instance, for learners who are not taught mathematics in their mother tongue. In this paper, the…

In order to examine whether syntactic processing is a necessary prerequisite for semantic integration in Japanese, cortical activation was monitored while participants engaged in silent reading task. Congruous sentences (CON), semantic violation sentences (V-SEM), and syntactic violation sentences (V-SYN) were presented in the experiment. The…

Recursive NPs are difficult to produce and late to emerge. We compare prosodic and syntactic abilities in Japanese-speaking five- and six-year-olds (n = 28) and adults (n = 10). It is reported that syntactic structure in Japanese is prosodically marked via downstep and metrical boost. Results of an elicited imitation task suggested that children…

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…

Research on second language (L2) pronoun use in null-argument languages has traditionally focused on whether or not a speaker's first language (L1) also allows null pronouns. However, recent studies have pointed out that it is equally important to consider the specific linguistic properties of overt pronouns in the L1 and L2, which may differ even…

The present study investigated the role of morphosyntactic information in the acquisition of transitive and intransitive verb argument structures (VAS) in the Japanese language, which allows massive omissions of arguments and case markers. In particular, we investigated how the 'variation sets' proposed by Küntay and Slobin work in Japanese.…

Purpose: This study investigated the auditory comprehension of Japanese sentences including relative clauses (RCs) by 52 Japanese-speaking children with typical development (TD) and 16 children with specific language impairment (SLI). Method: A picture-pointing task measured RC and main clause (MC) comprehension for object and subject relatives in…

This article investigates whether first-language (L1) Chinese-speaking learners of Japanese as a second language (L2) can acquire the knowledge that the reflexive pronoun jibun 'self' within the head noun phrase of Japanese relative clauses cannot refer to the relative clause subject. Successful acquisition would suggest that learners are able to…

Mental state terms are believed to be closely related to the development of Theory of Mind (ToM). This study focuses on mental state verbs (MSVs) and investigates how they are used by Japanese-speaking mother-child dyads compared to their English-speaking counterparts. Analyses of their spontaneous speech from the CHILDES archives show that…

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…

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…

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…

The work of translation seems to be much easier with the assistance of web-based Machine Translation such as Google Translate. Does it work well? This study aims at finding how Google translates academic texts from Indonesian into English. It is also to find the extent to which Google Translate accurately and naturally transfers such texts. The…
