Ambiguity was divided into semantic and affective ambiguity, and their effects on the aesthetic evaluation of haiku were examined for Japanese and German speakers. 450 Japanese and 373 German speakers evaluated 36 haiku for 10 items. The results showed that as semantic ambiguity increased, the aesthetic evaluation of haiku decreased. As a measure of affective ambiguity, we focused on awe and nostalgia, which encompass both positive and negative emotions, and the more they felt these emotions, the higher the aesthetic evaluation. These tendencies were greater for German speakers than Japanese. The reasons for the effects of two kinds of ambiguity on aesthetic evaluation of haiku and the cultural differences will be discussed.

芸術の創作において，知覚や感覚運動処理などの身体に基づく要素を利用することの重要性は，様々な先行研究により指摘されている。本研究では，言語芸術の一領域である俳句において，その創作に関わる知覚のうち，言葉の響きに対する知覚が活性化した状態で創作を行うことの効果について検討する。具体的には，日常的な俳句創作経験を有しない大学生・大学院生を対象としたオンライン創作実験を行い，実験で作られた俳句とその創作プロセスをそれぞれ分析する。
