Profile

At the JEONG Lab,

We investigate how people learn and use multiple languages, and how the brain supports these processes. Using neuroimaging techniques such as fMRI and behavioral experiments, we explore how memory, emotion, and social interaction influence language.

We also aim to uncover, from both neurocognitive and social perspectives, the mechanisms by which individuals learn languages, communicate, and make multilingual and culturally grounded behavioral choices in diverse and international contexts.

Our current research topics include:

  • Exploring similarities and differences between first and second languages
  • Studying the mechanisms of language control in bilinguals
  • Analyzing the effects of nonverbal factors (e.g., gestures, facial expressions, face-to-face interaction) on language communication
  • Investigating the relationship between language and emotion
  • Understanding how context and environment affect language learning and communication, including individual differences
  • Examining social learning models in language acquisition
  • Uncovering the cognitive mechanisms behind language choice during disasters

and more.

    This study examines the neural mechanisms behind integrating syntactic and information structures during sentence comprehension using functional Magnetic Resonance Imaging. Focusing on Japanese sentences with canonical (SOV) and non-canonical (OSV) word orders, the study revealed distinct neural networks responsible for processing these linguistic structures. The left opercular part of the inferior frontal gyrus, left premotor area, and left posterior superior/middle temporal gyrus were primarily involved in syntactic processing. In contrast, the right inferior frontal sulcus, bilateral intraparietal sulci, and the left triangular part of the inferior frontal gyrus were linked to information structure processing. Importantly, the left opercular part of the inferior frontal gyrus (BA44) played a crucial role in integrating these structures during the later stages of comprehension, particularly when processing the second noun phrase. These findings enhance our understanding of the complex interplay between syntactic and information structures in language comprehension.

    In computational neurolinguistics, it has been demonstrated that hierarchical models such as recurrent neural network grammars (RNNGs), which jointly generate word sequences and their syntactic structures via the syntactic composition, better explained human brain activity than sequential models such as long short-term memory networks (LSTMs). However, the vanilla RNNG has employed the top-down parsing strategy, which has been pointed out in the psycholinguistics literature as suboptimal especially for head-final/left-branching languages, and alternatively the left-corner parsing strategy has been proposed as the psychologically plausible parsing strategy. In this article, building on this line of inquiry, we investigate not only whether hierarchical models like RNNGs better explain human brain activity than sequential models like LSTMs, but also which parsing strategy is more neurobiologically plausible, by developing a novel fMRI corpus where participants read newspaper articles in a head-final/left-branching language, namely Japanese, through the naturalistic fMRI experiment. The results revealed that left-corner RNNGs outperformed both LSTMs and top-down RNNGs in the left inferior frontal and temporal-parietal regions, suggesting that there are certain brain regions that localize the syntactic composition with the left-corner parsing strategy.

    This fMRI study explored the relationship between social interactions and neural representations of emotionality in a foreign language (LX). Forty-five late learners of Japanese performed an auditory Japanese lexical decision task involving positive and negative words. The intensity of their social interactions with native Japanese speakers was measured using the Study Abroad Social Interaction Questionnaire. Activity in the left ventral striatum significantly correlated with social interaction intensity for positive words, while the right amygdala showed a significant correlation for negative words. These results indicate neural representations of LX emotional words link with the intensity of social interactions. Furthermore, LX negative words activated the left inferior frontal gyrus more than positive and neutral words, suggesting greater cognitive effort for processing negative words, aligning with a bias in adult social interactions towards more positively-valenced language. Overall, our findings underscore the importance of social interaction experiences in the processing of LX emotional words.

    This chapter focuses on the social second language learning (SL2) framework, which considers second language (L2) learning through social interaction and integration of information in the real world or in simulated social contexts. Specifically, the chapter discusses how SL2 provides a new framework for thinking about L2 versus first language (L1) differences and their corresponding neural correlates. The chapter compares the manner and context in which adults typically learn L2 with the way children naturally acquire L1, pointing to the significant theoretical implications of SL2. Then, properties are identified that make SL2 distinctive and advantageous to L2 learners, with a discussion of how this framework can be applied to the study of theoretical issues underlying L2 learning. Additionally, the chapter discusses the neural representations with respect to the increasing recognition of the right-hemisphere participation in SL2. Finally, the practical applications in technology-enhanced language learning are highlighted.

    Development of valid tasks that tap into implicit knowledge is a prerequisite for understanding the interface between explicit and implicit grammatical knowledge in second language (L2) acquisition. However, the extent to which elicited imitation tasks (EITs) draw on implicit or/and explicit knowledge has been a subject of controversy, due in part to the limitations of behavioral methods. To overcome this drawback, in this study, we used functional magnetic resonance imaging (fMRI) to examine the neural circuits underlying explicit and implicit knowledge (i.e., declarative and procedural memory) during the listening and speaking phases of an EIT performed by advanced L2 speakers of Japanese living in Japan. While the behavioral data suggest that the EIT primarily draws on automatized (speeded-up) explicit knowledge, the neuroimaging data revealed learners’ dynamic use of explicit and implicit knowledge during its comprehension and production phases. Higher explicit knowledge scores (derived from a metalinguistic knowledge task) were associated with greater declarative memory (left hippocampus) activation during the speaking EIT phase, indicating a prominent role of explicit knowledge in production. During the listening phase, however, higher explicit knowledge scores predicted lower activation in declarative memory (left hippocampus) and higher activation in procedural memory (left inferior frontal gyrus), suggesting that explicit knowledge plays both inhibitory and facilitative role in the use of implicit knowledge for comprehension. Taken together, these findings suggest that advanced L2 speakers utilize their explicit and implicit knowledge efficiently and dynamically—characterized as a hallmark of automaticity—for comprehension and production during the EIT.

    In this study, neural representation of adult second language (L2) speakers’ implicit grammatical knowledge was investigated. Advanced L2 speakers of Japanese living in Japan, as well as L1 Japanese speakers, performed a word-monitoring task (proposed as an implicit knowledge test) in the MRI scanner. Behavioral measures were obtained from aptitude tests for explicit (language analytic ability) and implicit (statistical learning ability) learning. Findings indicate that, although both L1 and L2 speakers recruited neural circuits associated with procedural memory during the word-monitoring task, different brain regions were activated: premotor cortex (L1 speakers) and left caudate (L2 speakers). The premotor cortex activation was weaker in L2 than L1 speakers but was positively correlated with the left caudate activation, suggesting that their grammatical knowledge, while less automatized, was still developing. Behavioral sensitivity to errors was predicted only by explicit language aptitude, which may play a key role in the automatization of grammatical knowledge.

  13. Neural correlates of Japanese honorific agreement processing mediated by socio-pragmatic factors: An fMRI study International-journal Peer-reviewed

    Socio-pragmatic factors, such as social roles and language experience, could be key variables influencing language processing. However, little is known regarding the neural correlates of syntactic processing mediated by socio-pragmatic factors. Honorific agreement in Japanese is well-suited for the investigation of this issue. Japanese honorifics are governed by socio-pragmatic and syntactic rules. Lower social status speakers are expected to address higher social status counterparts in accordance with these rules. This linguistic skill is typically developed through language experience accrued in social contexts. The present functional magnetic resonance imaging study investigated the neural correlates of the honorific agreement processing mediated by socio-pragmatic factors. Thirty-three native Japanese speakers performed a socio-pragmatic judgment task containing sentence conditions manipulated by conventionality (i.e., conventional vs. unconventional) and speaker (lower-status vs. higher-status). The lower-status conditions elicited significantly more activation of the left inferior frontal gyrus (IFG), bilateral insula, and dorsal medial prefrontal cortex than the higher-status ones, irrespective of conventionality. This suggests that social cues (i.e., speaker social status) trigger computation of honorific agreement via the left IFG. Furthermore, the conventional conditions significantly enhanced activation of the bilateral anterior temporal lobes (ATLs), compared with the unconventional conditions. Finally, the listener's experience with honorific use in the workplace was positively correlated with activation of the left inferior parietal lobule (IPL) during comprehension of conventional honorific utterances. Our findings demonstrate the importance of socio-pragmatic factors in Japanese honorific agreement processing, which involves the ATLs and IPL.

    Extending the paradigm in L1 acquisition, scholars have begun to investigate whether participants’ domain-general ability to represent, encode, and integrate spectral and temporal dimensions of sounds (i.e., auditory processing) could be a potential determinant of the outcomes of post-pubertal L2 speech learning. The current study set out to test the hypothesis that auditory processing makes a UNIQUE contribution to L2 speech acquisition, for 70 Japanese classroom learners of English with different levels of L2 proficiency when biographical backgrounds (length of instruction and immersion) AND memory abilities (working, declarative, and procedural memory) are controlled for. Auditory processing loaded onto modality-general capacities to represent and incorporate anchor stimuli (relative to target stimuli) into long-term memory in an implicit fashion, but dissociated from explicit abilities to remember, associate, and elaborate sensory information. Auditory processing explained a small-to-medium amount of variance in L2 speech learning, even after the other potentially confounding variables were statistically factored out.

    Flow is a highly motivated and affectively positive state in which a person is deeply engaged in an activity and feeling enjoyment from it. In collaborative activities, it would be optimal if all participants were in a state of flow. However, flow states fluctuate amongst individuals due to differences in the dynamics of motivation and cognition. To explore the possibility that inter-brain synchronization can provide a quantitative measure of the convergence and divergence of collective motivational dynamics, we conducted a pilot study to investigate the relationship between inter-brain synchronization and the interpersonal similarity of flow state dynamics during the collaborative learning process. In two English as a Foreign Language (EFL) classes, students were divided into groups of three-four and seated at desks facing each other while conducting a 60-min group work. In both classes, two groups with four members were randomly selected, and their medial prefrontal neural activities were measured simultaneously using wireless functional near-infrared spectroscopy (fNIRS) devices. Later the participants observed their own activities on recorded videos and retrospectively rated their subjective degree of flow state on a seven-point scale for each 2-min period. For the pairs of students whose neural activities were measured, the similarity of their flow experience dynamics was evaluated by the temporal correlation between their flow ratings. Prefrontal inter-brain synchronization of the same student pairs during group work was evaluated using wavelet transform coherence. Statistical analyses revealed that: (1) flow dynamics were significantly more similar for the student pairs within the same group compared to the pairs of students assigned across different groups; (2) prefrontal inter-brain synchronization in the relatively short time scale (9.3–13.9 s) was significantly higher for the within-group pairs than for the cross-group pairs; and (3) the prefrontal inter-brain synchronization at the same short time scale was significantly and positively correlated with the similarity of flow dynamics, even after controlling for the effects of within- vs. cross-group pair types from the two variables. These suggest that inter-brain synchronization can indeed provide a quantitative measure for converging and diverging collective motivational dynamics during collaborative learning, with higher inter-brain synchronization corresponding to a more convergent flow experience.

    Humans learn languages in real-life situations by integrating multiple signals, including linguistic forms, their meanings, and the actions and intentions of speakers. However, little is known about the neural bases underlying the social learning of a second language (L2) in adults. In this study, 36 adults were asked to learn two sets of L2 spoken words through translation versus simulated social interactive videos (social learning). Brain activation during word learning was measured using fMRI. Greater activation was observed in the bilateral superior temporal sulcus, posterior middle temporal gyri, and right inferior parietal lobule during social learning as compared with translation learning. Furthermore, higher activity in the right temporal parietal junction, right hippocampus, and motor areas was observed during the initial stage of social learning, with the more successful performance being at the time of overnight testing. We argue that social learning may strengthen the link from new L2 forms to rich L2 semantic representations wherein memory properties are embodied, multimodal, and richly contextualized.

    For centuries, adults may have relied on pedagogies that promote rote memory for the learning of foreign languages through word associations and grammar rules. This contrasts sharply with child language learning which unfolds in socially interactive contexts. In this paper, we advocate an approach to study the social brain of language by grounding second language learning in social interaction. Evidence has accumulated from research in child language, education, and cognitive science pointing to the efficacy and significance of social learning. Work from several recent L2 studies also suggests positive brain changes along with enhanced behavioral outcomes as a result of social learning. Here we provide a blueprint for the brain network underlying social L2 learning, enabling the integration of neurocognitive bases with social cognition of second language while combining theories of language and memory with practical implications for the learning and teaching of a new language in adulthood.

    Physical synchrony has been suggested to have positive effects on not only concurrent but also subsequent communication, but the underlying neural processes are unclear. Using functional near-infrared spectroscopy (fNIRS) hyperscanning, we tested the effects of preceding physical synchrony on subsequent dyadic teaching-learning communication. Thirty-two pairs of participants performed two experimental sessions. In each session, they underwent a rhythmic arm movement block with synchronous or asynchronous conditions, and then taught/learned unknown words to/from each other according to a given scenario. Neural activities in their medial and left lateral prefrontal cortex (PFC) were measured and inter-brain synchronization (IBS) during the teaching-learning blocks was evaluated. Participants rated their subjective rapport during the teaching-learning blocks, and took a word memory test. The analyses revealed that (1) prior physical synchrony enhanced teacher-learner rapport; (2) prior physical synchrony also enhanced IBS in the lateral PFC; and (3) IBS changes correlated positively with rapport changes. Physical synchrony did however not affect word memory performance. These results suggest that IBS can be useful to measure the effects of social-bonding facilitation activities for educational communication.

    Older children are more successful at producing unfamiliar, non-native speech sounds than younger children during the initial stages of learning. To reveal the neuronal underpinning of the age-related increase in the accuracy of non-native speech production, we examined the developmental changes in activation involved in the production of novel speech sounds using functional magnetic resonance imaging. Healthy right-handed children (aged 6-18 years) were scanned while performing an overt repetition task and a perceptual task involving aurally presented non-native and native syllables. Productions of non-native speech sounds were recorded and evaluated by native speakers. The mouth regions in the bilateral primary sensorimotor areas were activated more significantly during the repetition task relative to the perceptual task. The hemodynamic response in the left inferior frontal gyrus pars opercularis (IFG pOp) specific to non-native speech sound production (defined by prior hypothesis) increased with age. Additionally, the accuracy of non-native speech sound production increased with age. These results provide the first evidence of developmental changes in the neural processes underlying the production of novel speech sounds. Our data further suggest that the recruitment of the left IFG pOp during the production of novel speech sounds was possibly enhanced due to the maturation of the neuronal circuits needed for speech motor planning. This, in turn, would lead to improvement in the ability to immediately imitate non-native speech.

    OBJECTIVE: Although brain structural studies have demonstrated the neural correlates of neuroticism, the outcomes are not easily identified because of the various possible brain regions involved, low statistical power (low number of subjects), and brain structural measures available, such as mean diffusivity (MD), which are more suitable than standard regional measures of grey and white-matter volume (rGMV, rWMV) and fractional anisotropy (FA). We hypothesized that neuroticism neural correlates could be detected by MD and differentially identified using other measures. We aimed to visualize the neural correlates of neuroticism. METHODS: A voxel-by-voxel regression analysis was performed using the MD, rGMV, rWMV, or FA value as the dependent variable and with neuroticism scores based on the NEO-FFI and its confounding factors as independent variables in 1207 (693 men and 514 women; age, 20.7 ± 1.8, 18-27 years), non-clinical students in a cross-sectional study. RESULTS: MD in the cortico- (orbitofrontal cortex, anterior cingulate cortex, and posterior insula) striatal- (caudate and putamen) thalamic loop regions, including the right posterior limb of the internal capsule, were positively associated with neuroticism using the threshold-free cluster enhancement method with a family-wise error-corrected threshold of P < 0.0125 (0.05/4, Bonferroni correction for four types of MRI data [MD, rGMV, rWMV, and FA]) at the whole-brain level. CONCLUSIONS: An increased MD has generally been associated with reduced neural tissues and possibly area function. Accordingly, this finding helps elucidate the mechanism of somatization in neuroticism because the regions related to neuroticism are considered neural correlates of somatoform disorders.

    Guilt, a self-conscious emotion, includes self-focused role taking and also correlates with other-oriented role-taking. Excess guilt proneness might be relevant to obsessive compulsive disorders. The white matter (WM) neural correlates of the degree of guilt have not yet been determined. We hypothesized that the WM structures involved in feelings of guilt are associated with social and moral cognition (inferior parietal lobule [IPL], prefrontal cortex [PFC], and cingulate), and aimed to visualize this using diffusion MRI. We investigated the association between regional WM structures (WM volume, and fractional anisotropy, and mean diffusivity [MD]), and feelings of guilt in 1196 healthy, young students using MRI and the Guilty Feeling Scale, which comprises interpersonal situation (IPS; guilt from hurting friends) and rule-breaking situation (RBS; deontological guilt) scores. The primary novel finding presented here is that MD in the right somatosensory and motor cortices from arm to hand were positively correlated with RBS scores. Further, consistent with our hypothesis, RBS scores were positively correlated with MD in the same regions. These results would be predicted by the Macbeth effect, an obsession with dirt leading to hand-washing rituals resulting from guilt, made famous by the Shakespearian character Lady Macbeth. "What, will these hands ne'er be clean?" William Shakespeare (Shakespeare, 1606) Macbeth.

    Time-compressed speech is an artificial form of rapidly presented speech. Training with time-compressed speech (TCSSL) in a second language leads to adaptation toward TCSSL. Here, we newly investigated the effects of 4 weeks of training with TCSSL on diverse cognitive functions and neural systems using the fractional amplitude of spontaneous low-frequency fluctuations (fALFF), resting-state functional connectivity (RSFC) with the left superior temporal gyrus (STG), fractional anisotropy (FA), and regional gray matter volume (rGMV) of young adults by magnetic resonance imaging. There were no significant differences in change of performance of measures of cognitive functions or second language skills after training with TCSSL compared with that of the active control group. However, compared with the active control group, training with TCSSL was associated with increased fALFF, RSFC, and FA and decreased rGMV involving areas in the left STG. These results lacked evidence of a far transfer effect of time-compressed speech training on a wide range of cognitive functions and second language skills in young adults. However, these results demonstrated effects of time-compressed speech training on gray and white matter structures as well as on resting-state intrinsic activity and connectivity involving the left STG, which plays a key role in listening comprehension.

    General self-efficacy (GSE) is an important factor in education, social participation, and medical treatment. However, the only study that has investigated the direct association between GSE and a neural correlate did not identify specific brain regions, rather only assessed brain structures, and included older adult subjects. GSE is related to motivation, physical activity, learning, the willingness to initiate behaviour and expend effort, and adjustment. Thus, it was hypothesized in the present study that the neural correlates of GSE might be related to changes in the basal ganglia, which is a region related to the abovementioned self-efficacy factors. This study aimed to identify the brain structures associated with GSE in healthy young adults (n = 1204, 691 males and 513 females, age 20.7 ± 1.8 years) using regional grey matter density and volume (rGMD and rGMV), fractional anisotropy (FA) and mean diffusivity (MD) analyses of magnetic resonance imaging (MRI) data. The findings showed that scores on the GSE Scale (GSES) were associated with a lower MD value in regions from the right putamen to the globus pallidum; however, there were no significant association between GSES scores and regional brain structures using the other analyses (rGMD, rGMV, and FA). Thus, the present findings indicated that the lenticular nucleus is a neural correlate of GSE.

    Although the prevalence of chronic fatigue is approximately 20% in healthy individuals, there are no studies of brain structure that elucidate the neural correlates of fatigue outside of clinical subjects. We hypothesized that fatigue without evidence of disease might be related to changes in the basal ganglia and prefrontal cortex and be implicated in fatigue with disease. We aimed to identify the white matter structures of fatigue in young subjects without disease using magnetic resonance imaging (MRI). Healthy young adults (n = 883; 489 males and 394 females) were recruited. As expected, the degrees of fatigue and motivation were associated with larger mean diffusivity (MD) in the right putamen, pallidus and caudate. Furthermore, the degree of physical activity was associated with a larger MD only in the right putamen. Accordingly, motivation was the best candidate for widespread basal ganglia, whereas physical activity might be the best candidate for the putamen. A plausible mechanism of fatigue may involve abnormal function of the motor system, as well as areas of the dopaminergic system in the basal ganglia that are associated with motivation and reward.

    When sounds occur with temporally structured patterns, we can feel a rhythm. To memorize a rhythm, perception of its temporal patterns and organization of them into a hierarchically structured sequence are necessary. On the other hand, rhythm perception can often cause unintentional body movements. Thus, we hypothesized that rhythm information can be manifested in two different ways; temporal and motor representations. The motor representation depends on effectors, such as the finger or foot, whereas the temporal representation is effector-independent. We tested our hypothesis with a working memory paradigm to elucidate neuronal correlates of temporal or motor representation of rhythm and to reveal the neural networks associated with these representations. We measured brain activity by fMRI while participants memorized rhythms and reproduced them by tapping with the right finger, left finger, or foot, or by articulation. The right inferior frontal gyrus and the inferior parietal lobule exhibited significant effector-independent activations during encoding and retrieval of rhythm information, whereas the left inferior parietal lobule and supplementary motor area (SMA) showed effector-dependent activations during retrieval. These results suggest that temporal sequences of rhythm are probably represented in the right fronto-parietal network, whereas motor sequences of rhythm can be represented in the SMA-parietal network.

    One of human-being specific activities, interpreting (oral translation), has been adopted as a popular method to enhance second language acquisition lately. The question, however, how interpreting is executed in human brains, remains largely unknown. In this paper, we present our fMRI (functional Magnetic Resonance Imaging) experimental results to investigate how cerebral cortices are activated when subjects are engaged in interpreting exercises. Twenty-one healthy, right-handed university student subjects participated in this study. We directly compared English to Japanese consecutive interpreting (EJ) to Japanese to English consecutive interpreting (JE) using subtraction method, as well as with sentence reconstruction tasks in Japanese (JJ) and English (EE), and with resting condition (Rest, or baseline). The direct subtraction analysis between EJ and JE left only a limited area: left superior temporal gyrus remained. In JE minus EJ (masked by EJ-Rest: P<0.05image), right and left precentral gyri, left thalamus, left and right superior temporal gyri, and left middle temporal gyrus are left, suggesting that JE recruited more extensive regions in comparison with EJ, despite that all sources of sentence recorded and used as stimuli were constructed to be at the same level of difficulty, either directly taken from MEXT (Ministry of Education, Culture, Sports, Science and Technology) -authorized popular textbooks used in Japanese public junior high schools, or translation of such sources. The conditions EJ, EE, and JJ showed very similar patterns of cortical activation, indicating that the conditions recruited similar brain regions: left and right superior temporal gyri, mainly left middle temporal gyrus,, left inferior frontal gyrus (opercular part and triangular part), left temporal lobe's lateral surface, and mainly left supplementary motor areas. EJ and JE commonly activated Inferior frontal gyri (opercular part and triangular part) and supplementary motor areas in both hemispheres. Kawashima (2004) reports that even a different-activity-related cortical activation serves as a preparatory activity for the individuals' following activity and enhances learning or delays development of dementia in older subjects. From the results, we infer that EE and JJ sentence reconstruction exercises that activated similar regions to those activated in consecutive interpreting might fit the purpose of consecutive interpreting training preparation.

    Processing speed can be considered as one aspect of proficiency of foreign language. In this study, we measured processing speed of English sentence comprehension by Japanese learners, and examined the relationship between their speed and their proficiency level of English. To this end, we used self-paced reading task of English sentences and Minimal English Test (MET) as an English proficiency test. In this paper, we report the preliminary results.

    Childhood is known to be the best time in life to acquire foreign speech sounds. Therefore, it is important for foreign language education to clarify the neural process relating to foreign speech sounds. Healthy right-handed children (aged 6-18 years) participated in this study. Using functional magnetic resonance imaging, we examined their brain activation during an overt repetition and perceptual task with native and non-native syllables. The results showed that brain activation in the left inferior frontal gyrus pars opercularis, which is thought to be involved in motor control for speech production, increased with age. Additionally, accuracy of the pronunciation of non-native syllables improved with age. Those results indicate that improvement in foreign speech pronunciation might reflect maturation of the left inferior frontal gyrus.

    We carried out an fMRI study to investigate whether the same brain regions are involved in processing first and second languages. Twenty-eight right-handed native speakers of Japanese participated in this study. Subjects were instructed to read active and passive sentences in Japanese and English and to judge the plausibility of the sentence. As a result, we found that both similarites and differences between Japanese and English in terms of the regions involved in the processing of passive sentences. These results suggest that the processing of a second language exhibits both similarities and differences as contrasted with that of a first language.

    The goal of the present study was to reveal neural basis for developmental changes in emotion perception with speech in East-Asian languages. We conducted an experiment using functional magnetic resonance to examine how young native Japanese speakers understand Japanese sentence-final particles (SFPs) ‘-ne’ and ‘-yo’, which have been assumed to have functions of empathy and emphasis, respectively. Results indicated that their understanding of the SFPs was associated with the neural activity in the several cortical areas which are known to be responsible for theory of mind (i.e., the ability to infer other’s mental state), attention, and empathy. Further continuous investigations which shed light on the age-related changes will be informative for finding better ways of inter-generational communication in aging society in East Asia.

    This project examined the nature, acquisition and processing of interlanguage competence in terms of grammatical illusions, which have been extensively observed in second language acquisition but have not received enough attention. To this end, we made detailed analyses of grammatical phenomena which seem to give rise to grammatical illusions. Based on the results, we have identified linguistic properties which are potentially difficult for second language learners to acquire and resist instruction. Thus, the acceptability of grammatical illusions can diagnose how second language learners construct and access linguistic representations in real-time. We also explored the extent to which linguistic approaches to second language acquisition provide insights for the language classroom and concluded that they can bridge a gap between theoretical linguistics and English pedagogy.

    Cross-linguistic influence is one factor that facilitates or hinders L2 grammar acquisition. We investigate cross-linguistic influence on the progress of L2 learning using artificial languages with two groups of native Japanese speakers. We created two artificial languages that had different syntactic features but shared the same vocabulary system. We clarified that the left IFG played the crucial role in the cross-linguistic influence. This finding suggested that the cross-linguistic influence due to the grammatical distance between L1 and L2 was explained by the recruitment of brain activation at the left IFG. In addition, it suggested that the cross-linguistic influence occurred proactively, regardless of L2 proficiency, and relied on the opercular part of the left IFG.

    In this study, we investigated Japanese EFL students' learning engagement using the concept of flow as a framework. Findings from both of the subjective and quantitative measurements indicate that (1) contrary to the flow theory, the participants experience increased engagement regardless of the task difficulty or their motivation level by working together, (2) demonstrates the great potential of neural synchrony as a quantitative measurement of group work. This fundamental research will lead to an improved understanding of educational communication and the development of neural synchrony as a practical assessment for learning.

    In this study, it was investigated whether synchrony between the teacher and the students during the warm-up activities and during the language learning tasks of an EFL lesson would occur. It was found that the synchrony was present during the warm-up activities and the language tasks; the synchrony of the warm-up activities before the language learning task did not influence the level of synchrony during the language learning tasks; the synchrony during the warm-up activities was greater than that during the language learning tasks; and a higher degree of brain synchronization occurred when more student body movements were observed in the warm-up activities.

    This fMRI study investigated the neural mechanisms underpinning the process by which second language learners receive feedback on erroneous utterances and modify their original utterances. The sample consisted of 30 healthy, right-handed Japanese undergraduate and graduate students with intermediate proficiency in English. Immediately after describing a picture (self-condition) or hearing the other’s utterance (other-condition), participants received feedback from the native listener and responded to it. Both self and other conditions elicited significant activation in the left inferior frontal gyrus. While the self-task elicited significant activation in the supplementary motor area, the premotor area, and the cerebellum, the other-condition elicited significant activation in the anterior cingulate cortex. Responding to feedback may promote not only linguistic processing but also behavioral adaptation and error monitoring.

    The present study investigated neural mechanisms of acquiring second language (L2) from communicative social contexts, comparing with first-language (L1) translation-based learning. The following three major findings emerged. First, behaviorally, learning from social contexts showed better performance than L1 translation-based learning. Second, learning from social contexts recruited more brain areas associated with language communication. Third, higher proficiency learners recruited the motor, social cognition and memory-related areas including hippocampus during the initial stage of learning from social contexts. These findings suggest an importance of learning from social contexts in L2 acquisition.
