Sound change in the lab: Exposure-induced vocalic chain shifts
Original language description
Previous research on perceptual adaptation in vowels has attested generalization of retuning across vowelheight counterparts. Our study tested for a labinduced chain shift. In a lexical decision task, we exposed U.S. English participants to words with either raised or lowered tokens of /i/, along with unmanipulated back vowels but no other front vowels. In subsequent categorization of the members of a [i]~[ɪ]~[ɛ] continuum, we found a difference between the raised- and lowered-/i/ participants in the location of the /i/-/ɪ/ boundary (replicating perceptual adaptation in vowels) as well as the /ɪ/-/ɛ/ boundary. Thus, the exposure-induced shift of /i/-/ɪ/ triggered a similar shift for the unexposed /ɪ/-/ɛ/ contrast, pointing to adaptation at the level of the vocalic system rather than the level of perceptual cues or low-evel auditory compensation.
