INTRODUCTIONDuring children's most formative years, many aspects of their growth and development are influenced by the socio‐economic status (SES) of their family (for a review, see Bradley & Corwyn, 2002). These early disparities in neurocognitive development have cascading effects on a range of long‐term developmental outcomes (Hair et al., 2015). Marked disparities are particularly evident in early language acquisition (e.g., Hart & Risley, 1995; Hoff, 2003; 2006; Kuchirko, 2019, but see Sperry et al., 2019). Thus far, effects of SES on language development have focused predominantly on vocabulary acquisition. In the present study, we investigated whether family SES predicts more primitive perceptual processes that precede the development of a vocabulary. Specifically, we examined whether infants’ abilities to detect phonetic contrasts are associated with variation in family SES.Several studies have revealed that effects of SES on language development originate in infancy and are rooted in the nature of child‐caregiver interaction. Although there is variation in the strength of SES effects across studies (e.g., Piot et al., 2022), in general, children from high‐SES families enjoy a more conversation‐rich environment (Fernald & Weisleder, 2015). Children in such environments profit from increased language input and develop larger and more diverse vocabularies (Rowe, 2008). They also build
