This study investigates four factors (age, sex, SES, and bilingualism) influencing children’s language attitude (LA) development. We examine LAs in monolingual (N = 46) and bilingual (N = 71) children (59–143 months) living in France using a matched guise experiment where the children evaluated normative and non-normative variants of five linguistic constructions in French. Using a mixed-effects model, we show that children’s preferences for normative variants increase with age, and each linguistic construction documented is subject to different attitudinal timeframes. The probabilities of preferring the normative variants are significantly higher for monolingual girls than for bilingual girls. Whilst lower-class and upper-class children’s LAs are similar, low-to-middle-class children’s responses are more random, which may illustrate the potential effects of linguistic insecurity. We discuss how the children’s construction of the sociocognitive representations of linguistic variation could be explained by considering children’s language exposure and experiences of socialisation.
