 It has been shown that children whose parents received more education and have higher SES have larger vocabularies and learn new words more quickly during early childhood while children with less educated parents and lower SES have a smaller vocabulary and a slower growth in their vocabulary skills (Arriaga, Fenson, Cronan & Pethick, 1998; Hart & Risley, 1995; Hoff, Laursen & Tardif, 2002; Hoff-Ginsberg, 1991; Lawrence & Shipley, 1996; Ninio, 1980).This correlation is due to the fact that more educated parents use more lexises when speaking to their children as opposed to parents who are less educated (Hart & Risley, 1995; Hoff, 2003 a; Huttenlocher, Vasilyeva, Waterfall, Vevea & Hedges, in press).Hoff's 2003 analysis supports this correlation and shows that the mean length of utterance and vocabulary of mothers who talk to their children is related to their SES status and thus child vocabulary development.
