“…Rather, some letter names and letter sounds are easier and hence learned before others (e.g., Justice, Pence, Bowles, & Wiggins, 2006; McBride-Chang, 1999; Petscher & Kim, 2011; Phillips, Piasta, Anthony, & Lonigan, 2012; Treiman & Kessler, 2003), indicating that specific letter-name and letter-sound knowledge varies in acquisition. For example, children learn the name and sound for the letter B earlier and more easily than for the letter F (Treiman & Kessler), and children learn the first letter of their names before other letters (Phillips et al, 2012; Treiman & Broderick, 1998).…”
