Something About the Way You Speak: A Meta-analysis on Children's Linguistic-based Social Preferences.

There is growing interest in the role of linguistic cues (accents, dialects, language) in driving children's social preferences. This meta-analysis integrated 131 effect sizes involving 2,680 infants and children from 2 days old to 11 years. Overall, children prefer native-accent, native-dialect, and native-language speakers over non-native counterparts (d = 0.57). Meta-regression highlighted that bilinguals (d = 0.93) do not exhibit less native-speaker preference compared to monolinguals (d = 0.62). Children displayed stronger preferences based on accent (d = 1.04) than dialect (d = 0.44) and language (d = 0.39). Children's cultural background, exposure to non-native speech, age, and preference measure were not significant moderators. The data are discussed in light of several theoretical explanations for when and why children show linguistic-based social preferences.
