Functional imaging methods show differences in the pattern of cerebral activation associated with the subject's native language (L1) compared with a second language (L2). In a recent PET investigation on bilingualism we showed that auditory processing of stories in L1 (Italian) engages the temporal lobes and temporoparietal cortex more extensively than L2 (English). However, in that study the I...

This study investigated how vowel epenthesis, a typical suprasegmental error produced by Japanese learners of English, is realized in their speech production of L2 English. We investigated two aspects: (i) whether loanword epenthesis phonology in Japanese transfers to English speech production, and (ii) how learners’ English proficiency level affects vowel epenthesis. In Japanese loanword phono...

In this study, we show that second-language (L2) spoken-word recognition is greatly influenced by syllable-structure differences between the native language (L1) and the second language (L2), and that L2 word-recognition accuracy is a reliable predictor of L2 word-production accuracy. Spanish-speaking English learners (experimental group) completed a listening task in which they monitored /(ǝ)s...

This study investigates L1-L2 interactions in relatively young Mandarin (L1)-English (L2) bilingual children through comparing their static and dynamic vowel acoustic features with those of age-matched corresponding monolingual children. Two groups of sequential bilingual children aged 5-6 years (one with low proficiency in English and the other with high proficiency in English) were recorded p...

This study explores the construct of lexical sophistication and its applications for measuring second language lexical and speaking proficiency. In doing so, the study introduces the Tool for the Automatic Analysis of LExical Sophistication (TAALES), which calculates text scores for 135 classic and newly developed lexical indices related to word frequency, range, bigram and trigram frequency, a...

Extensive research has shown that second language (L2) learners find it difficult to apply grammatical knowledge during real-time processing, especially when differences exist between the first (L1) and L2. The current study examines extent which British English-speaking of French can their subjunctive whether this ability is modulated by properties L1 grammar, and/or proficiency. Data from an ...

Prosody has been demonstrated to be a key component in second language acquisition and assessment. This study analyzes raters’ ability to distinguish different levels of L1 and L2 prosody when listening to filtered speech. The goal of this study is to investigate how many levels of prosodic proficiency can be made when it is isolated in a filtered speech condition. An experiment was conducted w...

The application of zone of proximal development (ZPD), as a major tenet of Vygotsky’s sociocultural theory (SCT, 1978), has recently been invited in the L2 learning/teaching profession. This study mainly examined whether Iranian EFL learners’ interactions in diverse ZPD-activated proximal contexts through the use of storytelling instruction could improve their oral (speaking) proficiency and at...

Second language comprehensibility and accentedness are highly complex phenomena, numerous studies have been conducted to better understand these constructs. However, research has seldom addressed L2 in relation speakers' proficiency the target language. This study explores English across three levels. The speakers were 60 teenaged Finns, half of them speaking Finnish as their L1 Finland-Swedish...
