“…The quality and amount of talk between caregivers and young children has been found to have a significant effect on language use and literacy development (Beals, 2001;Beals et al, 1994;Collins and Michaels, 1980;Davidson and Snow, 1995;DeTemple and Beals, 1991;Dickinson and Tabors, 2001;Dunn and Dunn, 1981;Hart and Risley, 1995;Hoff and Naigles, 2002;Huttenlocher et al, 2002;Dickinson and Tabors, 2001;Weizman and Snow, 2001), and may be related to within-culture differences in language tradition (e.g., Collins and Micheals, 1980;Heath, 1982). For example, Weizman and Snow (2001) found that the number of words in adult talk in adult-child dyads was positively associated with child vocabulary production and that the most sophisticated levels of talk (in terms of the vocabulary used) occurred during shared book reading, which has also been found to be a significant predictor of reading performance (e.g., Hart and Risley, 1995;Sénéchal and LeFevre, 2002).…”
