著者らによる手話対話解析や手話シャドーイング実験結果から，手話母語者は静の意味を手話のわた りの部分で認識していると予測している.本報告では，手話母語者の語彙認知構造の解明を目的とし，実験用の手話文を作成し，認知実験を行った.実験の結果，正文における2語日の出わたり区間におけるターゲット語の正答率が44％と高かった.わたりでのターゲット語の正答率は，2語目の出わたり区間と，ターゲット語である3語目の入りわたり区間で合計83％となり，手話母語者はターゲット語前のわたり区間で語を認知していることが多いことを確認した．%Authors presumed that the native signer is recognizing the sign meaning in the part of transition of sign from the sign language dialogue analysis and the sign shadowing experiment result. In this report, we aimed to clarify native signer's sign acknowledgment structure, the sign language example sentence was made, and the recognition experiment of the sign was done. As a result of the experiment, the correct answer rate of the target word between out-transition intervals of the second sign in the grammatical sentence was high with 44%. The correct answer rate of the target sign in transition became 83% between out-transition of the second sign and in-transition of the third sign. Therefore, it was confirmed that the native signer often recognized sign in the transition before the target sign.
