“…The purpose of this study was to investigate differences among subjective evaluations of Japanese vowels. Many researchers have examined Japanese sound symbolism in terms of word evaluation, word comprehension and word learning (e.g., Hamano, 1986;Hamano, 1998;Imai et al, 2008;Shinohara and Kawahara, 2010;Osaka, 2011;Imai and Kita, 2014;Asano et al, 2015;Hoshi et al, 2019;Kawahara, 2020;Motoki et al, 2020;Kambara and Umemura, 2021), while many other researchers have also examined sound symbolism in other languages, especially in European languages (e.g., Sapir, 1929;Newman, 1933;Klink, 2000;Perfors, 2004;Yorkston and Menon, 2004;Myers-Schultz et al, 2013;Wu et al, 2013;Adelman et al, 2018;Aryani and Jacobs, 2018;Aryani et al, 2018a;Ariyani et al, 2018b;Aryani et al, 2019). One of the reasons why sound symbolism researchers have focused on Japanese is the large number of sound-symbolic words in Japanese (Hamano, 1986;Hamano, 1998;Imai and Kita, 2014).…”
