Bilingual studies using alphabetic languages have shown parallel activation of two languages during word recognition. However, little is known about the brain mechanisms of language control during word comprehension with a logogram writing system. We manipulated the types of words (interlingual homographs (IH), cognates, and language-specific words) and the types of participants (Chinese (L1) Japanese (L2) bilinguals vs. Japanese monolinguals). Greater activation was found in the bilateral inferior frontal gyri, supplementary motor area, caudate nucleus and left fusiform gyrus, when the bilinguals processed IH, as compared to cognates. These areas were also commonly activated when the bilinguals processed L2 control words during an Ll lexical decision task. The areas function as the task/decision system that plays a role in cognitive control for resolving response conflict. Furthermore, the anterior cingulate cortex, left thalamus, and left middle temporal gyrus were activated during IH processing, suggesting resolution of the semantic conflict at the stimulus level (i.e., one logographic word having different meanings in the two languages).

Processing speed in a second language (L2) is considered an important characteristic of L2 profi ciencylevel assessment. However, all characteristics of processing speed in L2 learning remain unclear. The currentstudy demonstrates that L2 listening proficiency is more associated with processing speed than L2reading profi ciency. In this study, participants were asked to take an L2 profi ciency test consisting of listeningand reading sections, and to perform an L2 sentence comprehension task that measured the speed ofsentence and word processing in the L2. The result indicates that speed of L2 sentence comprehension correlateswith L2 listening profi ciency level, whereas all other results showed no statistical signifi cance. Thisfi nding supports the assumption that the speed of L2 sentence reading refl ects the speed of the real-timesentence comprehension performance that is required in L2 listening performance.

学習心理学、認知心理学、認知神経科学などの分野において、人間の記憶・学習への促進効果が見られるとされる、Generation effectとTesting effectという現象がある。本論文では、実際の大学英語教育の場において、特に英語能力が低い学習者層に対し、この二つの現象を援用した訓練を半年間週一回の補講において導入し、その効果が見られるか否かを検証した。方法として、補講を行った学習者群に対し、Generation effect/Testing effectに基づいて、通常講義で用いているテキスト内に提示された例文の和文英訳問題を繰り返し解かせる形式とした。本研究の解析では、講義開始前に行った簡易placement testのスコアと定期試験のスコアを項目反応理論により解析した後、補講を行った群（71名）と補講対象にならなかった群の中でplacement testが低かった学習者群（71名）とでスコアの群間比較を行った。その結果、講義前のplacement testから講義後の定期試験のスコアにおいて、補講受講群・非受講統制群ともに有意にスコア上での改善は見られたものの、群間でのスコアの改善度に有意な差は見られなかった。よって、講義自体の英語力向上効果はあったものの、半年間の補講による英語力の改善効果は見られなかった。本結果となった理由はいくつか考えられるが、講義ではe-learningを用いた適切なフィードバックが学習効果を促進させた可能性がある一方、補講では紙面による課題であったため、個別の学生へのフィードバックが機能し切れなかった可能性がある。この結果に基づき、補講の効果を上げる方法を改めて検討していく必要がある。

近年、学科試験を受けない形で大学に入学させる、アドミッションオフィス入学試験（AO入試）方式や推薦入試などによる入学者選抜方式の利用が増加している。主に高校における成績、各種部活動や委員会などの活動実績、志望理由、面接、小論文などにより、入学希望者を多角的に評価し、入学者を選抜する方法である。しかし、中央教育審議会の場などにおいて、これらのAO入試や推薦入試が大学生の基礎学力低下を引き起こしている可能性がある、と危惧する声も上がっている。このような状況に対し、本論文では、中学・高校・大学において必修科目とされている英語科目の成績を指標とし、入学試験の方式により分類した初年次学生の英語に関するテスト結果のうち、初年次前期の講義開始前に行った英語科目のプレースメントテスト、及び初年次前期の英語科目にて全学的に行った共通定期試験のスコアを項目反応理論による解析を通じて、入学試験区分によって実際の大学入学者の学力差が見られるのかを検証した。結果として、プレースメントテスト、定期試験ともに、AO入試の区分の学生のスコア平均は低く、学科試験を課す入試区分の学生のスコア平均が高かった。一方、学校法人内での特待生推薦入試の区分の学生はスコア平均が高く、一般入試やセンター試験など実質的に学科試験がある入学区分と同等の学力を持っていた。特待生推薦入試の区分では、全ての学生が特待生になるわけではないが、特待生の枠での採用が設定されていることから、学費の減免を目的として、優秀な学生が受験してきている可能性が示唆される。以上より、AO入試・推薦入試の区分が全て学力不足である、という短絡的な一般化には至らないことが確認され、特待生枠などの設定により、学科試験が課されずとも学力が高い学生を確保する方法がある可能性が示された。

Listeners often misperceive speech contexts that contain unattested, ill-formed phonological sequences and repair them to create well-formed or close-to-native sequences. However, what guides the misperception and repair processes still has to be studied in depth. In the present study, French adults and typically-developing children were presented aurally with monosyllabic pseudowords and their disyllabic /u/-inserted counterparts, with the well-formedness of the latters' onset clusters being manipulated (e.g., Bbal/ vs. /gmal/). Here, we showed that onset clusters are increasingly misperceived as universal sonority-related markedness increases, i.e., from the most well-formed through to the most ill-formed onset clusters (e.g., /gm/-> /bd ->/b/). A posteriori measurements confirmed that the misidentification is due to a phonological repair during which an illusory epenthetic /e/-like vowel, i.e., a prototypical vowel inserted in French (e.g., /b/), is inserted in order to restore an attested phonological CV syllable structure. But these patterns are not primarily affected by acoustic-phonetic cues or sonority-unrelated cues. Moreover, both sensitivity to universal sonority-related markedness and epenthetic repair were found to be available at an early age in children. These results strengthen the hypothesis that acoustic-phonetic cues and language-specific properties, such as statistical properties for example, are not solely responsible for speech perception.

日本では、大学の基礎教育として英語教育が重視されている。一方で、実証的・客観的に大学英語教育を評価・検討した結果を論文の形として公開している研究者は少ない。本論文では大学における初年次英語教育の効果につき、講義内で行われた習熟度テストによる英語能力の評価に加え、講義内容の評価に関する複数のアンケートによるデータ分析を通じ、より多角的に大学英語教育の効果を検証することを目的とした。その結果、半期での英語教育において着実な教育効果が見られ、さらには学生の英語に対する興味・自信が、より英語教育の効果を高めることが確認された。これらの結果は、一般的なモチベーション理論における知見とも一致するものであった。本論文でのデータはまだ基礎的な段階ではあるが、改めて学習内容への興味や自信が学習効果に影響を及ぼすことが確認されたことにより、大学英語教育において学生に英語学習への興味及び自信を持たせるかという観点を採り入れることがいかに重要であるか、ということを再確認することができた。

PLOS ONE, Volume：9, Number：3, First page：e93109, Mar. 2014, [Reviewed]
It is well known that case marker information and animacy information are incrementally used to comprehend sentences in head-final languages. However, it is still unclear how these two kinds of information are processed when they are in competition in a sentence's surface expression. The current study used sentences conveying the potentiality of some event (henceforth, potential sentences) in the Japanese language with theoretically canonical word order (dative-nominative/animate-inanimate order) and with scrambled word order (nominative-dative/inanimate-animate order). In Japanese, nominative-first case order and animate-inanimate animacy order are preferred to their reversed patterns in simplex sentences. Hence, in these potential sentences, case information and animacy information are in competition. The experiment consisted of a self-paced reading task testing two conditions (that is, canonical and scrambled potential sentences). Forty-five native speakers of Japanese participated. In our results, the canonical potential sentences showed a scrambling cost at the second argument position (the nominative argument). This result indicates that the theoretically scrambled case marker order (nominative-dative) is processed as a mentally canonical case marker order, suggesting that case information is used preferentially over animacy information when the two are in competition. The implications of our findings are discussed with regard to incremental simplex sentence comprehension models for head-final languages.

Introduction: In subject-object-verb (SOV) languages, such as Japanese, sentence processing proceeds incrementally to the late presentation of the head (verb). Japanese case particles play a crucial role in sentence processing; however, little is known about how these particles are processed. In particular, it is still unclear how the functional difference between case particles is represented in the human brain. Methods: In this study, we conducted an fMRI experiment using an event-related design to directly compare brain activity during Japanese case particle processing among the nominative case ga, accusative case o, and dative case ni. Twenty five native Japanese speakers were asked to judge whether the presented character was a particle in a particle judgment task and whether the character ended with a specific vowel in a phonological judgment task, which was used as a control condition. Results: A particle comparison demonstrated that the processing of ni was associated with significantly weaker brain activity than that of ga and o in the left middle frontal gyrus (MFG) and the inferior frontal gyrus (IFG). Significantly greater brain activity associated with ni relative to ga in the right IFG was also observed. Conclusion: These results suggest that the Japanese case particles ga, ni, and o are represented differently in the brain.

Introduction: How human brains acquire second languages (L2) is one of the fundamental questions in neuroscience and language science. However, it is unclear whether the first language (L1) has a cross-linguistic influence on the processing of L2. Methods: Here, we used functional magnetic resonance imaging to compare brain activities during L2 word reading tasks of phonographic Japanese Kana between two groups of learners of the Japanese language as their L2 and who had different orthographic backgrounds of their L1. For Chinese learners, a L1 of the Chinese language (Hanji) and a L2 of the Japanese Kana differed orthographically, whereas for Korean learners, a L1 of Korean Hangul and a L2 of Japanese Kana were similar. Results: Our analysis revealed that, although proficiency and the age of acquisition did not differ between the two groups, Chinese learners showed greater activation of the left middle frontal gyrus than Korean learners during L2 word reading. Conclusion: Our results provide evidence that strongly supported the hypothesis that cross-linguistic variations in orthography between L1 and L2 induce differential brain activation during L2 word reading, which has been proposed previously.

To date, the nature of the phonological deficit in developmental dyslexia is still debated. We concur with possible impairments in the representations of the universal phonological constraints that universally govern how phonemes co-occur as a source of this deficit. We were interested in whether and how dyslexic children have sensitivity to sonority-related markedness constraints. We tested 10 French dyslexic children compared with 20 typically developing chronological age-matched and reading level-matched controls. All were tested with two aurally administered syllable counting tasks that manipulated well-formedness of unattested consonant clusters, as determined by universal phonological sonority-related markedness constraints (onset clusters in Experiment 1; intervocalic clusters in Experiment 2). Surprisingly, dyslexic children's response patterns were similar to those in both control groups; as universal phonological sonority-related markedness increased, dyslexic children increasingly perceptually confused and phonologically repaired clusters with an illusory epenthetic vowel (e.g., /bal/). Although dyslexic children were systematically slower, like both control groups, they were influenced by universal sonority-related markedness constraints and hierarchically ranked constraints specific to French over evident acoustic-phonetic contrasts or sonority-unrelated cues. Our results are counterintuitive but innovative and compete to question an impaired universal phonological grammar because dyslexic children were found to have normal universal phonological constraints and were skilled to restore phonotactically legal syllable structures with a language-specific illusory epenthetic vowel (i.e., /e/4-like vowel). We discuss them regarding active phonological decoding and recoding processes within the framework of the optimality theory. (C) 2012 Elsevier Inc. All rights reserved.

The processing of grammatical and semantic relationships is important in sentence comprehension. Although previous studies have demonstrated brain activities during grammatical and semantic processing in declarative sentences, functional MRI (fMRI) evidence related to these processes in wh-questions is largely unavailable. In Japanese wh-questions, a wh-phrase is grammatically associated with the closest particle, and a sentential subject is semantically associated with the verb. These features in Japanese wh-questions enable us to make grammatical or semantic anomalies without adding other words or morphemes in the violation paradigm. According to this advantage of Japanese wh-questions, this fMRI study investigated the brain activities in Japanese native speakers during grammatical and semantic processing of wh-questions to judge whether or not presented sentences were natural Japanese sentences (naturalness decision task). Three types of wh-questions were presented: correct, grammatically anomalous, and semantically anomalous conditions. This study yielded three main findings. First, activity in the left inferior parietal lobule was greater during processing of grammatically anomalous than correct or semantically anomalous wh-questions. Second, activity in the left inferior frontal gyrus was greater during processing of semantically anomalous than correct or grammatically anomalous wh-questions. Finally, significant correlations were identified between activities in the left inferior parietal lobule and the left inferior frontal gyms during grammatically anomalous and semantically anomalous wh-questions. These findings suggest that the left inferior parietal and inferior frontal regions have differential contributions to the processing of grammatical and semantic relationships in wh-question sentences, and that the interaction between these regions could be essential in the comprehension of wh-questions by combining the grammatical process with the semantic process.

Background: Frustrating situations are encountered daily, and it is necessary to respond in an adaptive fashion. A psychological definition states that adaptive social behaviors are "self-performing" and "contain a solution." The present study investigated the neural correlates of adaptive social responses to frustrating situations by assessing the dimension of causal attribution. Based on attribution theory, internal causality refers to one's aptitudes that cause natural responses in real-life situations, whereas external causality refers to environmental factors, such as experimental conditions, causing such responses. To investigate the issue, we developed a novel approach that assesses causal attribution under experimental conditions. During fMRI scanning, subjects were required to engage in virtual frustrating situations and play the role of protagonists by verbalizing social responses, which were socially adaptive or non-adaptive. After fMRI scanning, the subjects reported their causal attribution index of the psychological reaction to the experimental condition. We performed a correlation analysis between the causal attribution index and brain activity. We hypothesized that the brain region whose activation would have a positive and negative correlation with the self-reported index of the causal attributions would be regarded as neural correlates of internal and external causal attribution of social responses, respectively.
Results: We found a significant negative correlation between external causal attribution and neural responses in the right anterior temporal lobe for adaptive social behaviors.
Conclusion: This region is involved in the integration of emotional and social information. These results suggest that, particularly in adaptive social behavior, the social demands of frustrating situations, which involve external causality, may be integrated by a neural response in the right anterior temporal lobe.

Recently, sentence comprehension in languages other than European languages has been investigated from a cross-linguistic perspective. In this paper, we examine whether and how animacy-related semantic information is used for real-time sentence comprehension in a SOV word order language (i.e., Japanese). Twenty-three Japanese native speakers participated in this study. They read semantically reversible and non-reversible sentences with canonical word order, and those with scrambled word order. In our results, the second argument position in reversible sentences took longer to read than that in non-reversible sentences, indicating that animacy information is used in second argument processing. In contrast, for the predicate position, there was no difference in reading times, suggesting that animacy information is NOT used in the predicate position. These results are discussed using the sentence comprehension models of an SOV word order language.

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.

In sentence comprehension research, the case system, which is one of the subsystems of the language processing system, has been assumed to play a crucial role in signifying relationships in sentences between noun phrases (NPs) and other elements, such as verbs, prepositions, nouns, and tense. However, so far, less attention has been paid to the question of how cases are processed in our brain. To this end, the current study used fMRI and scanned the brain activity of 15 native English speakers during an English-case processing task. The results showed that, while the processing of all cases activates the left inferior frontal gyrus and posterior part of the middle temporal gyrus, genitive case processing activates these two regions more than nominative and accusative case processing. Since the effect of the difference in behavioral performance among these three cases is excluded from brain activation data, the observed different brain activations would be due to the different processing patterns among the cases, indicating that cases are processed differently in our brains. The different brain activations between genitive case processing and nominative/accusative case processing may be due to the difference in structural complexity between them.

In order to clarify the relationship among grammatical knowledge, processing components, and neural substrates in sentence comprehension, we used functional magnetic resonance imaging to investigate how brain activation is affected by two types of scrambling (short scrambling and middle scrambling) in ditransitive sentences in Japanese. Short scrambling and middle scrambling enhanced activation in the anterior and posterior left inferior frontal gyrus respectively. This finding accords with the view that the anterior left inferior frontal gyrus is involved in the automatic processing that establishes a dependency relation between a verb and its arguments, and the posterior left inferior frontal gyrus supports this kind of processing through its role in verbal working memory. This result is more congruent with a process-based approach to neural bases for sentence processing, which searches for neurological correlates of psycholinguistically defined processing components, than with a grammar-based approach, which probes neural networks with the assumption that major grammatical operations are neurologically individuated. © Koizumi et al.

While a clear variability of canonical word order across languages has been found, such a finding is not reflected in recent neuroimaging studies of language processing. Languages having a canonical word order of Subject-Object-Verb (SOV) in a sentence make up approximately 43% of world languages, while languages having a Subject-Verb-Object (SVO) word order make up approximately 37%. Sufficient attention has not been given to this typological difference in neuroimaging studies. In this article, we review neuroimaging studies of sentence processing to examine whether the typological difference of canonical word order in a sentence is represented in brain activation results or not. As a result of this literature survey, an effect from the difference in canonical word order was found to exist between SVO and SOV languages for brain activation during sentence comprehension. This effect was found mainly in the left inferior and middle frontal gyri, precentral gyrus, supplemental motor area, inferior and middle temporal gyri, temporal pole, hippocampus, and cerebellum. These results imply that a difference in canonical word order causes a different sentence processing pattern, as well as a different load in the working memory process. © Hashimoto et al.

Adults seem to have greater difficulties than children in acquiring a second language (L2) because of the alleged "window of opportunity" around puberty. Postpuberty Japanese participants learned a new English rule with simplex sentences during one month of instruction, and then they were tested on "uninstructed complex sentences" as well as "instructed simplex sentences." The behavioral data show that they can acquire more knowledge than is instructed, suggesting the interweaving of nature (universal principles of grammar, UG) and nurture (instruction) in L2 acquisition. The comparison in the "uninstructed complex sentences" between post-instruction and pre-instruction using functional magnetic resonance imaging reveals a significant activation in Broca's area. Thus, this study provides new insight into Broca's area, where nature and nurture cooperate to produce L2 learners' rich linguistic knowledge. It also shows neural plasticity of adult L2 acquisition, arguing against a critical period hypothesis, at least in the domain of UG.

Sci. Sports Exerc., Vol. 43, No. 10, pp. 1857-1862, 2011. Introduction: Rugby is one of the most tactically complex sports. Rugby coaching theory suggests that rugby players need to possess various cognitive abilities. A previous study claimed that rugby players have high visuospatial awareness, which is induced by a strategy described as taking a "bird's eye view." Methods: To examine if there were differential cortical networks related to visuospatial processing tasks among top-level rugby players and control novices, we compared brain activities during a visuospatial processing task between 20 male top-level rugby players (Top) and 20 control novice males (Novice) using functional magnetic resonance imaging (fMRI). To avoid the effect of differential behavioral performances on brain activation, we recruited novices whose visuospatial ability was expected to match that of the rugby players. We adopted a 3-D mental rotation task during fMRI scanning as a visuospatial processing task. Results: Significantly greater activations from baseline were observed for the Top group than for the Novice group in the right superior parietal lobe and lateral occipital cortex. Significantly greater deactivations from baseline were observed for the Top group than for the Novice group in the right medial prefrontal cortex. Conclusions: The discrepancy between psychobehavioral outputs and the fMRI results suggested the existence of a cognitive strategy among top-level rugby players that differs from that among control novices. The greater activation of the right superior parietal lobe and lateral occipital cortex in top-level rugby players suggested a strategy involving visuospatial cognitive processing with respect to the bird's eye view. In addition, the right medial prefrontal cortex is known to be a part of the default mode networks, suggesting an additional cognitive load for the Top group when using the bird's-eye-view strategy. This further supported the existence of a specific cognitive strategy among top-level rugby players.

This study used functional magnetic resonance imaging (fMRI) to identify differences in the neural processes underlying direct and semidirect interviews. We examined brain activation patterns while 20 native speakers of Japanese participated in direct and semidirect interviews in both Japanese (first language [L1]) and English (second language [L2]). Significantly greater activation was observed in the regions involved in social communication (the medial prefrontal cortex and the bilateral posterior superior temporal sulci) during the direct interview conducted in the L2 than during the semidirect interview conducted in the L2. In contrast, both the direct and semidirect interviews conducted in the L1 produced similar increases in activation in the same brain areas as those observed during the L2 direct interview. These findings suggest that the direct interview may have elicited L2 communicative ability to a greater degree than the semidirect interview. Furthermore, during the L2 direct interview, activity in the right superior temporal region, which is involved in the processing of paralinguistic features (e. g., prosody and intonation), was positively correlated with increased L2 oral proficiency. Based on our findings, we conclude that the L2 direct interview may elicit more balanced and varied aspects of communicative ability than the L2 semidirect interview.

Brain changes morphologically and functionally as one grows. However, it is unclear how the change of functional brain activation during sentence comprehension occurs on development. We measured functional brain images during sentence comprehension tasks of 114 juveniles from six to eighteen years old (62 girls and 52 boys) by using functional magnetic resonance imaging (fMRI). We found that the brain activation of several right hemispheric brain regions negatively correlates with age for only boys. Also, the developmental change occurs linearly.

Working memory is the limited capacity storage system involved in the maintenance and manipulation of information over short periods of time. Individual capacity of working memory is associated with the integrity of white matter in the frontoparietal regions. It is unknown to what extent the integrity of white matter underlying the working memory system is plastic. Using voxel-based analysis (VBA) of fractional anisotropy (FA) measures of fiber tracts, we investigated the effect of working memory training on structural connectivity in an interventional study. The amount of working memory training correlated with increased FA in the white matter regions adjacent to the intraparietal sulcus and the anterior part of the body of the corpus callosum after training. These results showed training-induced plasticity in regions that are thought to be critical in working memory. As changes in myelination lead to FA changes in diffusion tensor imaging, a possible mechanism for the observed FA change is increased myelination after training. Observed structural changes may underlie previously reported improvement of working memory capacity, improvement of other cognitive functions, and altered functional activity following working memory training.

Successful sentence comprehension requires not only syntactic and lexico-semantic processing, but also the processing of peripheral linguistic phenomena. However, less research attention has been focused on the latter. In order to examine whether the processing of linguistic empathy is psycho- and neuro-physiological in the human brain, we compared behavioral and brain activity data during the processing of an Ageru sentence with those of processing a Kureru sentence in Japanese, which are different from each other in terms of the processing of linguistic empathy. While we found no statistical difference in behavioral data between the two conditions but a statistically much greater activation in the left premotor area for the processing of the Kureru sentence than for the processing of the Ageru sentence. However, taken together with previous findings, Our functional magnetic resonance imaging results suggest that the left premotor activation reflects not the processing of linguistic empathy per se, but rather the attentional shifting process of linguistic empathy in Kureru sentence comprehension.

Neuroimaging studies of second language (L2) comprehension have reported that the low L2 proficiency of non-proficient learners is associated with greater brain activation in several regions due to the increased deployment of resources to process a not-so-familiar language. However, until now, no attention has been paid to the possibility that the non-proficiency of such learners can actually lead to insufficient use of brain regions where the first language (L1) speakers show increased brain activation. Here, our fMRI study found that the left middle temporal gyrus was less active during the L2 lexical decision of non-proficient Chinese learners of Japanese as L2 than during the L1 lexical decision of native Japanese speakers. Our results indicate that the difficulty experienced by non-proficient L2 learners in L2 lexical decision is due to their less active use of the left middle temporal gyrus, which is, contrastively, used actively by L1 speakers in their L1 lexical decision. These results in turn suggest that left middle temporal activation reflects whether or not the lexical information of L2 words is formed appropriately as part of the L2 mental lexicon.

The present study aims to confirm the cortical correlates of scrambling effects, a free word order phenomenon that has been observed in a variety of cross-linguistic investigations but whose mechanism still remains unclarified. Many syntax-oriented hypotheses on scrambling have been provided to develop the structural basis of the free word order permutation in Japanese, leading to the most recent phrasal architecture, in which the object noun phrase of a transitive sentence "moves" to a higher position than the subject to form an asymmetric structure including antecedent-gap relationships. Such a configurational structure formed by scrambling operation predicts that the scrambled sentences have a more complex structure than canonical sentences, and that the former requires a greater burden on cognitive processes in related areas within the brain. Based on this general assumption, we employed an experimental method of whole-sentence presentation of Japanese transitive sentences, for both canonical transitive sentences (Subject-Object-Verb) and their scrambled counterparts (Object-Subject-Verb). The result showed more activation at the left inferior frontal gyrus (IFG) and the left dorsal prefrontal cortex (DPFC) during the comprehension of scrambled sentences than that of canonical sentences. This indicates, in accordance with previous findings on scrambling from neurolinguistic perspectives, that the scrambling in Japanese is indeed one of the grammatical operations and that the parsing strategy for the asymmetric antecedent-gap relationship demands an additional cognitive activation in the brain.

In order to comprehend a sentence, we need several sub-processes. For example, it is necessary to store phonological information tentatively to recognize a word from phonological input. Similarly, it is also necessary to store lexico-semantic information of words to compute a sentence-structure from these words. In this paper, we discuss how sub-processes for sentence comprehension interact with each other based on effective connectivity data of fMRI.

Electromagnetic source imaging techniques are usually limited by their low spatial resolution, even though these techniques have high temporal resolution. Our heuristic analysis shows that the spatial ambiguity of electromagnetic source localization arises from interference from other sources. In this paper, we suggest a new inverse solution based on the principle of spatial filtering to effectively suppress the interference from other sources, especially from the far sources. By means of this approach, functional MRI information can also be effectively integrated into the inverse solution to further improve spatial accuracy of source localization. Most importantly, the results of source localization by this approach are not significantly biased by incompatible fMRI information. Our simulations and experimental results using electroencephalography based on a realistic head model show that the Backus-Gilbert resolution spread function-con strained and functional MRI-guided spatial filtering suggested in this paper provide high spatial accuracy and resolution of source localization, even in the presence of multiple simultaneously active sources.

In this paper, we propose that functional brain imaging data can be applied to the assessment of language proficiency in foreign language learning. Functional brain imaging techniques can visualize how the human brain works during a cognitive task. Hence, by using such functional brain imaging data, we can assess whether a learner can properly comprehend a foreign language. Furthermore, such a database may enable us to apply the assessment of whether a new language education method has effective or not.

To examine whether the human beings are endowed with a specific neural substrate for sentence processing separable from working memory system, we compared brain activities for sentence processing with those for a manipulation process of stored information in working memory. Twenty right-handed Japanese native speakers performed reordering tasks with both sentence processing and manipulation process conditions. Based on our main finding that there was no significant difference in brain activation between these two processes, we concluded that it is the working memory system itself that engages sentence processing in the human brain.

The goal of this study was to examine the effect of the linguistic distance between a first language (L1) and a second language (L2) on neural activity during second language relative to first language processing. We compared different L1-L2 pairs in which different linguistic features characterize linguistic distance. Chinese and Korean native speakers were instructed to perform sentence comprehension tasks in two L2s (English and Japanese) and their respective L1s. Activation while understanding English sentences relative to understanding sentences in L1 was greater for the Korean group than the Chinese group in the left inferior frontal gyrus, bilateral posterior superior temporal gyri, and right cerebellum. Activation while understanding Japanese sentences relative to understanding sentences in L1 was greater for the Chinese group than the Korean group in the anterior portion of the left superior temporal gyrus. The results demonstrated that the location of the L2-L1 processing-induced cortical activation varies between different L1-L2 pairs.

We used functional magnetic resonance imaging (fMRI) to investigate whether activation in Broca's area is greater during the processing of passive versus active sentences in the brains of healthy subjects. Twenty Japanese native speakers performed a visual sentence comprehension task in which they were asked to read a visually presented sentence and to identify the agent or the patient in the sentence by pressing a button. We found that the processing of passive sentences elicited no greater activation than that of active sentences in Broca's area. However, passive sentences elicited greater activation than active sentences in the left frontal operculum and the inferior parietal lobule. Thus, our neuroimaging results suggest that deficits in the comprehension of passive sentences in Japanese aphasics are induced not by lesions to Broca's area, but to the left frontal operculum and/or the inferior parietal lobule.

A numeral quantifier in Japanese consists of a numeral and a classifier that agrees with the type of entity being counted. In this study we investigated, using event-related potentials, brain activities associated with the integration of a numeral classifier and a noun that denotes an entity⁄entities being counted.
Based on previous studies, we considered two hypotheses. If semantic processes are crucially involved in the integration of a noun and a numeral classifier, like selectional restriction between a verb and its object, N400 would be found when subjects read incorrect pairs of a noun and a numeral classifier. On the other hand, if the integration of a noun and a numeral classifier is morpho-syntactic in nature, parallel to gender agreement in European languages, then LAN would be elicited.
Results of our experiment showed that mismatch of a noun and a numeral classifier evoked N400. This suggests that a numeral classifier in Japanese semantically selects a noun denoting a certain type of entity.

In this study, we investigated two aspects of verb processing: first, whether verbs are processed differently from nouns; and second, how verbal morphology is processed. For this purpose, we used functional magnetic resonance imaging to compare three types of lexical processing in Japanese: the processing of nouns, unmarked active verbs, and inflected passive verbs. Twenty-eight healthy subjects were shown a lexical item and asked to judge whether the presented item was a legal word. Although all three conditions activated the bilateral inferior frontal, occipital, the left middle, and inferior temporal cortices, we found differences in the degree of activation for each condition. Verbs elicited greater activation in the left middle temporal gyrus than nouns, and inflected verbs showed greater activation in the left inferior frontal gyrus than unmarked verbs. This study demonstrates that although verbs are basically processed in the same cortical network as nouns, nouns and verbs elicit different degrees of activation due to the cognitive demands involved in lexical semantic processing. Furthermore, this study also shows that the left inferior frontal cortex is related to the processing of verbal inflectional morphology.

The question of whether the bilingual brain processes a first and second language (L1 and L2, respectively) differently is a central issue in many psycholinguistic and neurolinguistic studies. This study used functional magnetic resonance imaging (fMRI) to investigate whether late bilinguals process structurally complex sentences in L1 and L2 in different cortical networks. For this purpose, we directIN compared brain activity during the processing of active and passive sentences in both L1 and L2. We asked 36 healthy subjects to judge whether or not a presented sentence was semantically plausible. Both L1 and L2 activated the left hemispheric language-related regions such as the left inferior frontal, superior/middle temporal, and parietal cortices. However, we found different activation patterns between L1 and L2 in the processing of passive sentences. Passive sentences elicited greater activation than their active counterparts in the left pars triangularis, the premotor area, and the superior parietal lobule in Japanese, but not in English. Furthermore, there was a significant interaction between sentence type (active versus passive) and language (Japanese versus English) in the left pars orbitalis. The results of this study indicate that late bilinguals use similar cortical regions to comprehend both L1 and L2. However, when late bilinguals are presented with structurally complex sentences, the involvement of these regions differs between L1 and L2. These results suggest that, in addition to age of L2 acquisition and L2 proficiency, differences in grammatical construction affect cortical representation during the comprehension of L1 and L2.

Numeral classifiers (e.g. -hiki, -hon) are the suffixes used with numbers, which we usually use to count certain objects. The nouns choose what type of specific numeral classifiers should associate with them. The purpose of this study is to reveal, by using ERPs, what kind of brain activities are taking place when Japanese native speakers integrate nouns and numeral classifiers. Results of our experiment showed that mismatch of a noun and a numeral classifier evoked N400. This suggests that semantic processes are crucially involved in the integration of nouns and numeral classifiers in Japa...

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 ...

The purpose of this study was to clarify the relationship among foreign language proficiency level, language processing indices, and brain activity. This study revealed that there is no strong relationship between proficiency level and processing speed, but the processing speed of the foreign sentence comprehension correlates with that of the first language sentence comprehension. Regarding the relationship between foreign sentence comprehension speed can be estimated by the brain activity data.

The aim of current study was to clarify correct wrong linguistic information especially slip of tongue and re-comprehend it smoothly. Correction of wrong information is thought to be an essential function during communication. In this study, psychological and fMRI experiments were conducted to reveal the correct function. These results indicates that correction and short-term memory or working memory mutually works during real-time language processing.

The current research analyzed the relationship between L2 proficiency and the speed of vocabulary processing. An MEG date has still being analyzed and the results indicate that advanced learners are faster at lexical processing than beginners, and that beginners utilize broader areas of the brain in semantic processing. In addition, an effect of extensive reading on vocabulary processing and on reading speed has been researched, and it was found that extensive reading enhances not only reading proficiency but also listening proficiency.

We have established a method to build up a corpus (treebank) which has sufficient information to automatically obtain semantic representations with syntactic annotations from diverse linguistic texts in Modern Japanese. Following the method we have established, we have annotated more than 10,000 sentences. In particular, we have solved problems concerning syntactic annotation, i.e., collocations which function as single P's, collocations functioning as modal auxiliaries, and null elements.

This study examined whether second language (L2) speech proficiency measures might have corresponding biological bases. The participants were 55 Japanese university students with Japanese as first language (L1) and English as L2. They described pictures, using L1 and L2 (in different sessions), while fMRI brain scans were taken. The results indicate that L2 speech production requires more brain resources compared to L1 speech production. Preliminary data analyses also provide evidence that L2 proficiency indices are linked to variations in brain activity. Complexity in L2 speech (production of more elaborate utterances) was related to activation in the left hemisphere around Broca's area, while lack of fluency (high use of filled pauses in speech) and use of unfamiliar words in the L2 were both linked to some activation in the anterior part of Wernicke's area. These findings could help in the development of more efficacious instructional strategies for promoting L2 speech acquisition.

We have developed a syntactico-semantic system that is capable of analyzing the majority of basic japanese sentences, using Scope Control Theory, a semantic framework that gives an account of how sentences are formed based on the interpretability of sentences. We have built up a protoyype of Japanese Treebank in order to evaluate the obtained results. Furthermore, we hacve proposed a neuro-cognitive sentence processing model which fits in with the data obtained from neuro-image experiments.

The current research tried to answer the question whether beginners understand English words through Japanese and whether they will be able to process English words directly in English as their level increase. Experiments were conducted in order to observe the process of L2 vocabulary processing in our brain with MEG (magnetoencephalography). The results indicate that advanced learners are faster at lexical processing than beginners, and that beginners utilize broader areas of the brain in semantic processing.

To understand the nature of Japanese language processing, this research project based on neuroimaging techniques examined lexical, morphological, sentential, and pragmatic aspects of the language. The Japanese language processing was also examined by contrasting the performance of native speakers with that of non-native speakers. These fMRI studies were able to demonstrate that some aspects of the Japanese language processing is unique、while some others are universal in nature. In addition, we conducted basic neurological studies in which we proposed a new methodology for simultaneous recording of EEG and fMRI and provided a new insight for better understanding of EEG source localization.
