  • Prediction of Second Language Proficiency Based on Electroencephalographic Signals Measured While Listening to Natural Speech.

    　View Summary

    This study had two goals: to clarify the relationship between electroencephalographic (EEG) features estimated while non-native speakers listened to a second language (L2) and their proficiency in L2 determined by a conventional paper test and to provide a predictive model for L2 proficiency based on EEG features. We measured EEG signals from 205 native Japanese speakers, who varied widely in English proficiency while they listened to natural speech in English. Following the EEG measurement, they completed a conventional English listening test for Japanese speakers. We estimated multivariate temporal response functions separately for word class, speech rate, word position, and parts of speech. We found significant negative correlations between listening score and 17 EEG features, which included peak latency of early components (corresponding to N1 and P2) for both open and closed class words and peak latency and amplitude of a late component (corresponding to N400) for open class words. On the basis of the EEG features, we generated a predictive model for Japanese speakers' English listening proficiency. The correlation coefficient between the true and predicted listening scores was 0.51. Our results suggest that L2 or foreign language ability can be assessed using neural signatures measured while listening to natural speech, without the need of a conventional paper test.

  • Children's Learning of a Semantics-Free Artificial Grammar with Center Embedding

    Shiro Ojima, Kazuo Okanoya

    BIOLINGUISTICS   14   21 - 48  2020  [Refereed]

    　View Summary

    Whether non-human animals have an ability to learn and process center embedding, a core property of human language syntax, is still debated. Artificial-grammar learning (AGL) has been used to compare humans and animals in the learning of center embedding. However, up until now, human participants have only included adults, and data on children, who are the key players of natural language acquisition, are lacking. We created a novel game-like experimental paradigm combining the go/no-go procedure often used in animal research with the stepwise learning methods found effective in human adults' center-embedding learning. Here we report that some children succeeded in learning a semantics-free artificial grammar with center embedding (A(2)B(2) grammar) in the auditory modality. Although their success rate was lower than adults', the successful children looked as efficient learners as adults. Where children struggled, their memory capacity seemed to have limited their AGL performance.

    　View Summary

    This study investigated the effects of the onset age of English learning and the total amount of English learing on the English-speaking ability of native Japanese speakers. Japanese-speaking children attending elementary school or junior high school who had high English proficiency took part. Linguistic analyses of their English-speaking data suggested their superiority to Japanese university students in fluency and the amount of speech produced. The key to their high speaking performance seemed to be both the early onset of learning and the massive amount of exposure to English at home obtained through learning materials.

    　View Summary

    The question why languages in the world have their own grammar has been addressed among researchers on historical changes in language and biological evolution of human being. The present study approaches this problem from the cognitive neuroscience perspective. This approach aims to answer the question how the mechanisms for real-time language processing comes to be integrated into the functions of human brain. As a result of this study, we revealed the characteristics of phonological, syntactic, semantic, and pragmatic processing of language through a series of experiment measuring brain activities during language comprehension or production. Furthermore, we conducted a study on building a computational model of language learning and examined its validity in light of experimental data. The result showed that models that incorporate direction of the rules are more effective than previous models without such consideration.

    　View Summary

    A miniature artificial language typically consists of a small set of grammatical rules and vocabulary items. One advantage of using an artificial language is that learners can acquire it in a much shorter time compared to a natural human language. This research aimed to study humans’ language learning abilities using an artificial language learning paradigm. In particular, we focused on the learnability of so-called center embedding, one of the core characteristics of human language. Our research suggests that an artificial language equipped with center embedding is difficult for human adults to acquire, requiring a number of conditions to be met. It has also been suggested that human children’s acquisition of this type of artificial language is more likely to fail and is slower compared to adults.

  • 早期英語学習の認知脳科学的研究：　研究基盤形成と発展を目指して

    2023  

    　View Summary

    本課題の研究代表者は2023年4月に早稲田大学に着任したため、まずは本予算を用いて研究環境の整備を実施した。これと同時に、2023年度は研究代表者を務める科研費基盤B課題「早期英語学習の認知脳科学的研究」の最終年度であったため、次の科研費申請に向けた研究基盤の形成を目指した。この課題では、早期英語学習の認知脳科学的研究における国内最高の研究拠点の形成、および、研究成果の発信による教育や子育てへの社会的貢献を目指しており、これまでの科研費研究期間の中で多くのデータが取得できている。この科研費課題を補完する形で23年度は脳機能計測や言語・心理学的実験による追加データの取得および取得済データの分析、成果の発表を行った。このプロセスの中で、本学において長く研究を行っていくために十分な実験環境の構築（脳波計測に必要な施設の移設など）や、脳機能計測を実施できる研究アシスタントの新たな育成なども行った。研究成果については、国内の主要な言語学の学会における特別公開シンポジウムで社会に向けて広く発信し（YouTubeで公開）、大きな反響を得た。また、バイリンガル研究会の基調講演や海外の学会での発表なども行った。本研究課題においては特にインターナショナルスクールに通う児童からの言語データ・脳機能データを多く取得できたが、これらの分析については、来年度以降に持ち越しとなる。来年度に向けて既に新たな科研費および特定課題研究が採択されており、今年度よりもさらに規模を大きくして研究を進めていきたい。
