In three artificial language experiments, we explored the rate at which adults learned associations between linguistic variation and speaker characteristics. Within each of the experiments, we observed that listeners sociolinguistic learning occurred, regardless of whether the speaker characteristic is social (race and sex/gender) or nonsocial (hat wearing), or whether they heard a phonological or morphological variant. However, we found that listener's initial expectations of what social properties were predictive of linguistic variation differed, impacting overall performance. First, participants were much more likely to assume that a phonological variant was predicted by a social property than a nonsocial property (Experiment 1). Most interestingly, participants were more likely to privilege speaker race than sex/gender, but only in the case of a phonological variant (Experiments 2 and 3). The same effect was found in both White and Black participants, though White participants were more likely to correctly articulate which speaker characteristic explained the variation, suggesting that sociolinguistic learning hinges on real-world experiences with language and social diversity.
Public Significance StatementSociolinguistic associations are formed when listeners link specific speech properties (e.g., accents and suffix use) with a specific speaker property (e.g., race and sex/gender), which in turn can influence their expectations of how a new person will speak. The present study suggests that some sociolinguistic associations may be learned more easily than others. To be more precise, listeners expect that speaker race is important to how speakers pronounce words, at least when compared to the social property sex/gender. Furthermore, the background and experiences of the listener may influence how they learn sociolinguistic associations. That is, the listener's own race or their experience with race may affect how quickly they form an association between a speaker's race and how they pronounce words. The results of this study highlight the importance of listeners' previous experiences with diversity on their future interactions with new speakers.
