“…The kappa effect in the auditory mode was investigated in the present study. The kappa effect has been tested more often in the visual mode (Cohen, Hansel, & Sylvester, 1953Collyer, 1977;Miyatani, 1984Miyatani, -1985Sarrazin, Giraudo, Pailhous, & Bootsma, 2004), and even in the tactile mode (Goldreich, 2007;Suto, 1952Suto, , 1955Suto, , 1957. There are researches testing the kappa effect in the auditory mode, but most of them focused on the effects of frequency distance (difference), instead of spatial distance, on the perception of time duration (Cohen, Hansel, & Sylvester, 1954;Jones & Huang, 1982;Shigeno, 1986;Yoblick & Salvendy, 1970).…”
