“…Most estimates suggest that children aged 5-6 years have a working vocabulary of approximately 2500-5000 words (Beck & McKeown, 1991) and during early school years children learn about 3000 words per year roughly 8 words per day (Baumann & Kameenui, 1991;Beck & McKeown, 1991;Graves, 1986). Estimates suggest that only ~10% of words acquired in a year are learned through direct instruction by adults, with the majority of words learned incidentally through more implicit means, including conversation, television, and, in particular, story exposure (Aktar, 2004;Alloway, Williams, Jones, & Cochrane, 2013;Elley, 1989;Biemiller, 2003;Nagy & Herman, 1987). Indeed, the most commonly observed effect of early story exposure during the preschool (Hamilton, 2014;Justice, Meier & Walpole, 2005;Senechal & Cornell, 1993;Waisk & Bond, 2001;Walsh & Blewitt, 2006) and primary school years (Dickinson, 1984;Elley, 1989;Nagy, Anderson, & Herman, 1987;Penno, Wilkinson & Moore, 2002;Robbins & Ehri, 1994).…”
