In this paper, we propose a statistical evaluation method of pronunciation proficiency and intelligibility for presentations made in English by native Japanese speakers. We statistically analyzed the actual utterances of speakers to find combinations of acoustic and linguistic features with high correlation between the scores estimated by the…

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…

Fluency development instruction lacks in reading in Japanese as a foreign language instruction. This study examined how 34 upper-intermediate level learners of Japanese responded when they first experienced pleasure reading and speed reading. The participants also engaged in intensive reading, the main component of which was translation. Survey…

This study examines the influence of experience with a second language (L2) on the perception of phonological contrasts in a third language (L3). This study contributes to L3 phonology by examining the influence of L2 phonological perception abilities on the perception of an L3 at the beginner level. Participants were native speakers of Korean…

This study investigates 128 Chinese college students to examine the effects of their musical aptitude and musical training on phonological production in four foreign languages. Results show that musically-trained students remarkably possessed stronger musical aptitude than those without musical training and performed better than their counterpart…

This article calls attention to a facet of the expertise of second language (L2) learners of Japanese at the intersection of language, memory, gesture, and the psycholinguistics of a logographic writing system. Previous research has shown that adult L2 learners of Japanese living in Japan (similarly to native speakers of Japanese) often…

Maintaining children's heritage language (HL) is a challenging task for linguistic minorities around the world. While many Japanese heritage children in Sydney attend weekend HL schools, they typically discontinue attendance before, or during, secondary school. To date, no longitudinal study has investigated what happens to their HL maintenance…

Adopting a longitudinal design, this study investigates the effects of foreign language anxiety on foreign language proficiency over time within English and Japanese learning contexts. It also explores the stability of anxiety in English and Japanese over time and the stability of anxiety across English and Japanese. Chinese university students (N…

This dissertation investigated the effects of technological mediation on second language (L2) learning, focusing, as a case study, on gains in listening perception of the subtle but important feature of pitch placement in Japanese. Pitch accent can be difficult to perceive for non-native speakers whose first language (L1) does not rely on pitch or…

The visual complexity of orthographies varies across writing systems. Prior research has shown that complexity strongly influences the initial stage of reading development: the perceptual learning of grapheme forms. This study presents a computational simulation that examines the degree to which visual complexity leads to grapheme learning…

Captions and subtitles as a form of scaffolding for audiovisual materials has gained much attention in second or foreign language (L2) learning in recent years and various studies report their positive effects on learners' listening comprehension. However, few attempts have been made to investigate how textual information specifically affects the…

The current study investigated how recasts can promote the L2 pronunciation development of word-initial /?/ by Japanese learners of English in relation to two developmental stages of English /?/ acquisition (i.e. change in second formant [F2] ? change in third formant [F3]) as well as four affecting variables (i.e. the amount of recasts and…

This article reports on the development and use of the Developmental Sentence Scoring for Japanese (DSSJ), a new morpho-syntactical measure for Japanese constructed after the model of Lee's English Developmental Sentence Scoring model. Using this measure, the authors calculated DSSJ scores for 84 children divided into six age groups between 2;8…

The present study aims to demonstrate how the estimation of vocabulary size might be affected by two neglected factors in vocabulary size tests. The first factor is randomization of question sequence, as opposed to the traditional high-to-low frequency sequencing. The second factor is learners' confidence in choosing the correct meaning for a…

The present study examined various aspects of the development of learners' fluency in Japanese using a large set of speech samples collected over a long period, using an online speaking practice/assessment system called "Speak Everywhere." The purpose of the present study was to examine: (1) how the fluency related measures changed over…
