“…Some researchers have looked for frequency effects in children’s learning of letter names by examining the frequency with which letters occur in books, or specifically in books that are designed for children. Such effects are small and in some cases not statistically significant among 3- to 5-year-old learners of the Latin alphabet (Ecalle, 2004 for French; Evans et al, 2006; Treiman & Kessler 2004; Treiman et al, 2006, 2007; Turnbull, Bowles, Skibbe, Justice, & Wiggins, in press for English). However, the effects appear to increase with age (Bouchière, Ponce, & Foulin, 2010 for French), and a study of Israeli 5- and 6-year-olds found statistically significant frequency effects in letter naming (Treiman et al, 2007).…”
