Outline of Final Research Achievements

The aim of this research project was to examine connections between linguistic and perceptual features. We conducted online and offline studies. In this research, we found the following results. First, memory performances of linguistic features could be linked to perceptual and emotional evaluations to perceptual stimuli associated with the linguistic features. Second, results showed that recognition and retrieval speeds to an associative condition of a word and picture were faster than those to an associative condition of a word and definition in a second language. Third, vowels and consonants in linguistic features affect perceptual and emotional imageries from the linguistic features.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は，言語情報と連合した感覚情報の評価が言語情報の記憶成績と関連することや，言語情報と指示対象を連合学習する際に，言語情報と字義的定義の連合学習よりも，言語情報と指示対象となる感覚情報の連合学習の方が，言語情報から指示対象を思い出すスピードが速いこと，などを明らかにしたことによって，言語心理学における大きな理論の一つである二重符号化理論の発展に貢献できた点にある。本研究の社会的意義は，教科書や視聴覚教材を用いた教育だけでなく，視聴覚以外の感覚刺激も積極的に取り入れた体験的教育の重要性を示唆している点にある。
