The functional aspect of consciousness (access consciousness) and its impact on language acquisition and linguistic/nonlinguistic behavior

In second language acquisition in particular, the role of consciousness during acquisition and the use of acquired knowledge is a central issue, and much research has thus far been conducted (on conscious and unconscious learning and knowledge). My research attempts to answer the following questions: What factors trigger consciousness in learning and knowledge? How is conscious and unconscious learning related to conscious and unconscious knowledge? To what extent is unconscious language acquisition and processing possible in second language acquisition? How does the acquisition of a first language differ from the acquisition of a second language because of the function of consciousness?

Phenomenal aspects of consciousness and human cognition observed through language

I have been exploring the phenomenal aspects of consciousness, or how people subjectively view the world, using methods of experimental psychology or psycholinguistics. In particular, I am interested in how language and consciousness are related and whether (and to what extent) consciousness and perception differ due to differences in language systems. My research is based on the cognitive linguistic perspective of how people mentally represent meanings and abstract concepts, the cognitive science research of embodied or grounded cognition that proposes modal representations, mental simulations, bodily states, and situated action underlying cognition, and linguistic relativism and thinking-for-speaking research on how language affects individual cognition and linguistic/nonlinguistic behavior. Through these studies, I seek to shed light on the structure of mental representations in human cognition and explore the universality and cultural diversity of mind and language.

Cognitive philosophical investigation on language and consciousness and ontological discussions of psychological entities

Based on the results of the fundamental research described above, I have attempted to explore the question, “What does it mean to learn a language?” using philosophical frameworks. In addition to the goal of understanding human cognition in general, this research not only involves judgments about the value of language education but also how to scientifically explore invisible objects in psychology and linguistics.

意識の機能的側面（アクセス意識）とその言語習得・行動への影響

特に第二言語習得においては、習得時および習得された知識が使用される時点における「意識」の役割が研究分野において中心的な問題として取り扱われ、これまで多くの研究が蓄積されています（意識的・無意識的学習および知識の研究）。その学習・知識にかかわる意識はどのような要因に惹起されるのか、意識的・無意識的学習と意識的・無意識的知識がどのようにかかわるのか、第二言語習得において無意識的な言語の習得・処理はどの程度可能・必要なのか、また意識の機能に起因して第一言語の習得と第二言語の習得はどのように異なるのか———これらの問いに答えるような理論を模索しています。

言語を通して覗く意識の現象的側面（現象的意識）

人が主観的に世界をどのように見ているかという意識の現象的側面を、心理言語学的手法で探究しています。特に、言語と意識内容がどのようにかかわるか、言語体系の異なりに起因して意識内容、認識が（どの程度）異なるのかということに興味を持っています。人が意味や抽象的な概念をどのように心的に表象しているかという言語学的観点からの研究、我々の認知的な情報処理や我々のもつ概念がどのように基盤化（grounded）されているのかという「身体化された認知（embodied cognition）」および「基盤化された認知（grounded cognition）」の認知科学的研究、言語が個人の認知や行動に（どのように）影響するかという「言語相対論」やThinking-for-speakingの研究を通して、人間認知における心的表象の構造に光を当て、心とことばにおける普遍性と文化的多様性を探ろうとしています。

言語と意識に関わる認知哲学的思索およびそれに基づく心的実在物の存在論的議論

上述の基礎的研究の結果を踏まえ、「言語を学ぶとはどういうことか」という問いを哲学的な枠組みを用いて探究したいと考えています。この研究内容は、人間認知一般を理解するという目的以外に、言語教育の価値に対する判断や、目に見えない対象をどのように研究していくか（心やことばを扱う際に対象となるものはたいてい目に見えません）という科学哲学的な問いにも関わります。
