Abstract
|
|
|
|
The current study explores whether speaker variability in the fronted articulations of Seoul Korean affricates can beexplained by cognitive differences measured by individual autistic traits. The goal was to explore Yu’s (2010; 2013) proposalthat individual differences in cognitive style can be an important factor in speakers’ use of sound variants. The spectral peakfrequencies (SPF) of affricates relative to those of fricatives, reported in Kong et al. (2014), were used to acousticallyrepresent the relative degree of anterior place of constriction. When these individual SPFs were related to the scores ofAutistic-Spectrum Quotients (Baron-Cohen et al., 2001), a correlation was found for the male speakers, but not for the femalespeakers, such that speakers of more anterior affricate productions scored low in AQs. Discussion is made with respect tohow these findings are in line with Yu’s proposal.
