 note = {本研究課題では、日本語を母語とする英語学習者の音声言語の知覚・認知のプロセスの解明に不可欠な、言語の知覚単位の解明を目的とし、日本語母語話者の言語知覚において、大きな役割を果たしているモーラの実在について調査を行った（Sugai, 2017）。その結果、250 msあたりにモーラの境界が存在する強い可能性が示された。また、発話速度によって音声の知覚単位が変動する可能性を探った結果、発話速度が遅い（モーラ長が長い）と1モーラ、速い（モーラ長が短い）と2モーラが知覚単位となる可能性が示された。しかしこの結果については調査手法によって結果にばらつきが見られるのでさらなる調査を進める必要がある。, In this research project, the aim was to elucidate the perception and cognition process of English learners whose native language is Japanese, and to clarify the perceptual units of language that are essential for this purpose. A study was conducted on the existence of mora, which plays a significant role in the language perception of native Japanese speakers (Sugai, 2017). The results indicated a strong possibility of a mora boundary around 250 ms. Additionally, an investigation was conducted to explore the potential variability of perceptual units in speech due to speaking rate. The results suggested that slower speaking rates (with longer mora duration) may perceive one mora unit, while faster speaking rates (with shorter mora duration) may perceive two mora units. However, as there was variation in the results depending on the research methods employed, further investigation is needed to validate these findings., 研究分野：心理言語学},
