Article
Listeners regularly comprehend continuous speech despite noisy conditions. Previous studies show that neural tracking of speech degrades under noise, predicts comprehension, and increases for non-native listeners. We test the hypothesis that listeners similarly increase tracking for both L2 and noisy L1 speech, after adjusting for comprehension. Tw...
Article
Domain-general cognitive control is closely related to language control during bilingual language production. Previous neural imaging studies have revealed a highly overlapped but rewired brain network for language control and nonverbal cognitive control. In the present study, we examined this issue from a training perspective. Two groups of partic...

The cognitive function of the human cerebellum could be characterized as enigmatic. However, researchers have attempted to detail the comprehensive role of the cerebellum in several cognitive processes in recent years. Here, using functional magnetic resonance imaging (fMRI) and transcranial direct current stimulation (tDCS), we revealed different...
Article
We investigated whether fluent language production is associated with greater skill in resolving lexical competition during spoken word recognition and ignoring irrelevant information in non-linguistic tasks. Native English monolinguals and native English L2 learners, who varied on measures of discourse/verbal fluency and cognitive control, identif...
Article
When bilinguals switch languages they regulate the more dominant language to enable spoken production in the less dominant language. How do they engage cognitive control to accomplish regulation? We examined this issue by comparing the consequences of training on language switching in two different contexts. Chinese-English bilinguals were immersed...

Listeners regularly comprehend continuous speech despite noisy conditions. Previous studies show that cortical entrainment to speech degrades under noise, predicts comprehension, and increases for non-native listeners. We test the hypothesis that listeners similarly increase cortical entrainment for both L2 and noisy L1 speech, after controlling fo...

Full-text available
People who grow up speaking a language without lexical tones typically find it difficult to master tonal languages after childhood. Accumulating research suggests that much of the challenge for these second language (L2) speakers has to do not with identification of the tones themselves, but with the bindings between tones and lexical units. The qu...
Article
We evaluated external and internal sources of variation in second language (L2) and native language (L1) proficiency among college students. One hundred and twelve native-English L2 learners completed measures of L1 and L2 speaking proficiency, working memory and cognitive control and provided self-ratings of language exposure and use. When conside...

Writing sequences play an important role in handwriting of Chinese characters. However, little is known regarding the integral brain patterns and network mechanisms of processing Chinese character writing sequences. The present study decoded brain patterns during observing Chinese characters in motion by using multi-voxel pattern analysis, meta-ana...
Article
Full-text available
Background The neural networks underpinning language control and domain-general executive functions overlap in bilinguals, but existing evidence is mainly correlative. Here, we present the first neurofunctional evidence for a transfer effect between (domain-general) inhibitory control and language control through training. We trained Chinese–Englis...
Article
The Principle A of the Binding Theory (Chomsky, 1981, 1986) prescribes that a reflexive should refer to a local antecedent within the local syntactic domain containing the reflexive. However, the Chinese (simple) reflexive ziji (自己, standing for oneself) can refer not only to a local but also to a long-distance antecedent in sentences, leaving room...
Article
Full-text available
Many studies have examined the cognitive and neural mechanisms of bilingual language control, but few of them have captured the pattern information of brain activation. However, language control is a functional combination of both cognitive control and language production which demonstrates distinct patterns of neural representations under differen...
Article
Full-text available
Bilingual language experience, such as switching between languages, has been shown to shape both cognitive and neural mechanisms of non-linguistic cognitive control. However, the neural adaptations induced by language switching remain unclear. Using fMRI, the current study examined the impact of short-term language switching training on the neural...
Article
Full-text available
It has been documented that conflict adaptation (conflict resolution in a task enhanced by that in a previous task) exists not only in the same domain but also across different domains with shared cognitive control mechanisms. For the first time, the present study adopted a cross-task adaptive blocked design to examine the relationship between bili...

Article
In recent years, some studies have started to explore the impact of individual general executive functions (EFs) on bilingual language control. To our knowledge, few studies have systematically examined various components of EFs on different levels of language control in bilinguals. In two experiments, we investigated the effects of two components...
Article
We investigated whether the features of the second language (L2) matter when we consider the consequence of short-term L2 immersion on performance in the native language (L1). We compared L1 performance in English-speaking learners of a typologically-dissimilar L2-Chinese immersed in Chinese while living in Beijing, China and learners of a typologi...
Article
Full-text available
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 whe...
Article
Full-text available
Lexical tones are widely believed to be a formidable learning challenge for adult speakers of nontonal languages. While difficulties—as well as rapid improvements—are well documented for beginning second language (L2) learners, research with more advanced learners is needed to understand how tone perception difficulties impact word recognition once...
Article
The present study investigates the effect of mixed language training on the language control mechanism of bilingual language production. Two groups of unbalanced bilinguals were enrolled in pre- and post-tests using the picture naming task, but only the experimental group participated in an eight-day dual-language training session. Event-related po...
Article
When bilinguals intend to speak in their first (L1) or second language (L2) according to the environment, a brain network involving cortical-subcortical regions is recruited to resolve cross-language interference. Research has found that the activation of these brain regions varies with language contexts. However, previous studies have not yet exam...
Article
The present study investigated the effect of language-switching training on the neural correlates of both reactive and proactive control in bilingual language production, as well as the modulating role of the proficiency level of the second language (L2). During the pre-test, Chinese-English bilinguals performed a picture-naming task while being sc...

Previous research has shown that training on inhibitory control (IC) leads to functional neural plastic changes, although this effect on individuals with different levels of IC abilities has yet to be studied. Here, we examined the individual differences in IC abilities of 85 participants, who performed a Simon task while undergoing a functional ma...
Article
Culture influences its individuals' behaviors in a subtle yet effective way. While the physical experience of emotions is largely biologically determined, emotion perception and processing can still be culturally specific. The present study investigates the neural mechanisms that underlie emotion processing and experience in two cultures. Participa...
Article
For bilinguals, language control is needed for selecting the target language during language production. Numerous studies have examined the neural correlates of language control and shown a close relationship between language control and domain-general cognitive control. However, it remains unknown how these brain regions coordinate with each other...
Article
As the ability to recognize and communicate emotions is crucial to mental health, it is important to understand the representation and processing of emotion concepts. This study examined brain electrophysiological responses to nouns that denote emotions (e.g., guilt and joy) in comparison to nouns that denote abstract (e.g., theme) and concrete ent...

The neural mechanism for selectively tuning in to a target speaker while tuning out the others in a multi-speaker situation (i.e., the cocktail-party effect) remains elusive. Here we addressed this issue by measuring brain activity simultaneously from a listener and from multiple speakers while they were involved in naturalistic conversations. Resu...
Article
It is commonly believed that second language (L2) acquisition of lexical tones presents a major challenge for learners from nontonal language backgrounds. This belief is somewhat at odds with research that consistently shows beginning learners making quick gains through focused tone training, as well as research showing advanced learners achieving...
