Social Priming: Exploring the Effects of Speaker Race and Ethnicity on Perception of Second Language Accents.

Abstract

Listeners use more than just acoustic information when processing speech. Social information, such as a speaker's perceived race or ethnicity, can also affect the processing of the speech signal, in some cases facilitating perception ("social priming"). We aimed to replicate and extend this line of inquiry, examining effects of multiple social primes (i.e., a Middle Eastern, White, or East Asian face, or a control silhouette image) on the perception of Mandarin Chinese-accented English and Arabic-accented English. By including uncommon priming combinations (e.g., a Middle Eastern prime for a Mandarin accent), we aimed to test the specificity of social primes: For example, can a Middle Eastern face facilitate perception of both Arabic-accented English and Mandarin-accented English? Contrary to our predictions, our results indicated no facilitative social priming effects for either of the second language (L2) accents. Results for our examination of specificity were mixed. Trends in the data indicated that the combination of an East Asian prime with Arabic accent resulted in lower accuracy as compared with a White prime, but the combination of a Middle Eastern prime with a Mandarin accent did not (and may have actually benefited listeners to some degree). We conclude that the specificity of priming effects may depend on listeners' level of familiarity with a given accent and/or racial/ethnic group and that the mixed outcomes in the current work motivate further inquiries to determine whether social priming effects for L2-accented speech may be smaller than previously hypothesized and/or highly dependent on listener experience.
