Bilinguals are able to compose expressions across their languages with seeming ease. This phenomenon, commonly referred to as "code-switching," has challenged both theoretical models in linguistics as well as neurobiological models of language processing. And yet, our models of the bilingual brain and the language processing mechanism…

Adult second language learners arrive at the language learning situation with an already formed first language grammar system in place. The study of cross-language similarity across the first and second languages explores how the similarities and differences in the two languages make learning more or less difficult, particularly for adult…

It has been proposed that second language (L2) learners differ from native speakers in processing due to either influence from their native language or an inability to integrate information from multiple linguistic domains in a second language. To shed new light on the underlying mechanism of L2 processing, we used an event-related potentials…

Learning new languages is a complex task involving both explicit and implicit processes (i.e., that do/do not involve awareness). Understanding how these processes interact is essential to a full account of second language (L2) learning, but accounts vary as to whether explicit processes help (e.g., DeKeyser, 2007), hinder (e.g., Ellis &…

Event concepts of common verbs (e.g. "eat," "sleep") can be broadly shared across languages, but a given language's rules for subcategorization are largely arbitrary and vary substantially across languages. When subcategorization information does not match between first language (L1) and second language (L2), how does this…

Previous event-related potentials (ERP) research has investigated how foreign accent modulates listeners' neural responses to lexical-semantic and morphosyntactic errors. We extended this line of research to consider whether pronunciation errors in Mandarin Chinese are processed differently when a foreign-accented speaker makes them relative to…

In this paper, we first introduce functional magnetic resonance imaging (fMRI), followed by a review of three themes of neuroimaging research on the neural correlates of reading-related skills: (1) typical and struggling readers, including developmental dyslexics, (2) an inverted U-shaped function in second-language reading that portrays an…

The present study examines both properties of the language and properties of the learner to better understand variability at the earliest stages of second language (L2) acquisition. We used event-related potentials, an oral production task, and a battery of individual differences measures to examine the processing of number and gender agreement in…

In 3 ERP experiments, we investigated how experienced L2 speakers process natural and correct syntactic input that deviates from their own, sometimes incorrect, syntactic representations. Our previous study (Lemhöfer, Schriefers, & Indefrey, 2014) had shown that L2 speakers do engage in native-like syntactic processing of gender agreement but…

The usage-based theory highlights the important role of linguistic input in language acquisition, and assumes that syntactic representations could be entrenched through usage or exposure. In the present study, we used the event-related potential technique to investigate the long-term effect of input training on second language (L2) syntactic…

The perfective aspect marker in Chinese is partly functionally similar to inflectional suffixes in Indo-European languages but is non-inflectional and lexical in nature, lying thus at the semantics-syntax interface. This provides us with the opportunity to compare directly the syntactic and semantic constraints during second language (L2) sentence…

This study is about artificial neural network modeling of the linguistic challenges encountered by students learning Turkish as a foreign language in universities in France. The study was conducted in four universities where Turkish is taught as an optional foreign language. Sixty-six students whose mother tongues were either Arabic or French…

The role of prosodic information in sentence processing is not usually addressed in second language (L2) instruction, and neurocognitive studies on prosody-syntax interactions are rare. Here we compare event-related potentials (ERP) of Chinese and German learners of English L2 to those of native English speakers and show how first language (L1)…

This experimental study examined how VSTF (Visual-Syntactic Text Formatting)-based text benefits reading speed, reading comprehension, reading efficiency and retention for middle and high school students. Prospective within-subjects tests were conducted in Japan on a total of 132 students: 76 high school students from 12th grade and 56 middle…
