“…The validity of addressing only the number of words poor children hear in the preschool years as the cause of their inadequate school achievement has been questioned by anthropologists, linguists, and educators (e.g., Avineri & Johnson, 2015;Blum, 2015;Johnson, 2015). Critics charge that the Word Gap ignores the culturally defined contexts in which language is learned and used, and they take issue with the assumption that maternal vocabulary spoken directly to the child is the only speech that matters for language learning (Avineri & Johnson, 2015;Miller & Sperry, 2012;Zentella, 2015). They note that the practice of talking to the child in dyadic interaction is socioculturally defined (Brown & Gaskins, 2014;Duranti, Ochs, & Schieffelin, 2012;Miller, Cho, & Bracey, 2005), does not exist in many cultures (Brown & Gaskins, 2014;Duranti et al, 2012;Rogoff, 2003), and is not necessary for language learning (Akhtar & Gernsbacher, 2007).…”
