1990 年，美國總統布希宣布二十世紀的這最後十年為研究「大腦的十年」（the decade of the brain）；認知神經科學界的巨學葛詹尼加（Michael Gazzaniga）更宣稱二十一世紀為腦研究世紀（the century of the brain），這些宣言無疑地象徵著當前人類最重要的科學課題是-揭開人頓大腦的神秘面紗。由於大腦與人們的聽、說、讀、寫等語言能力與認知行為關係密切。因此，本文試圖從人腦的生理機制的角度來探討聽覺理解困難，來一窺個體內在心理運作歷程之個中奧妙，並闡明其教育上的意義。

　　The U.S. President Bush designated the 1990s as "the Decade of the Brain" ; Michael S. Gazzaniga also declared that the twenty-first century is "the Century of the Brain". There is no doubt that these declarations signify the most important scientific lessons learned from science and also lift the veil of our marvelous brains. Since the brain is related to our language competence (such as listening, speaking, reading and writing abilities) and cognitive behavior of human beings, this article contributes to discover difficulties of listening comprehension within our brains from the viewpoint of the mechanisms of the brain, and tries to understand cognitive process in individuals. In addition, the educational meanings for practitioners are also discussed.
