Recent research has suggested that the contribution of individual sociolinguistic variables to the social perception of a speaker is influenced by other available information about the speaker (Campbell-Kibler, 2007; Pharao, Maegaard, Spindler Møller, & Kristiansen, 2014). Here we investigate the impact of listener awareness of regional sociolinguistic variation on sociolinguistic perception. Specifically, we compare how the social meanings attributed to word-internal, preconsonantal /s/ differ based on whether the listeners and speakers use predominantly /s/-weakening Puerto Rican Spanish or predominantly non–/s/-weakening Mexican Spanish. We find that for measures of status, Puerto Rican and Mexican listeners both show a smaller effect of /s/ when rating Puerto Rican as opposed to Mexican speakers. However, we see no effect of speaker nationality on heteronormativity, and Puerto Rican listeners and male Mexican listeners rate strong /s/ as less heteronormative across the board. Mexican female listeners, however, rate strong /s/ as more heteronormative. These results suggest that listeners integrate their own local ideologies with their understanding of regional differences when socially evaluating language variation.
