“…We excluded print exposure studies that reported no child outcomes or outcomes other than comprehension and technical reading and spelling skills, such as science tests or social ability tasks (e.g., Bråten et al, 1999; Burgess, 2005; Castles, Datta, Gayan, & Olson, 1999; Chomsky, 1972; Curry, Parrila, Stephenson, Kirby, & Catterson, 2004; Korat & Schiff, 2005; Lee & Krashen, 1996; Long & Prat, 2002; Mar, Oatley, Hirsh, dela Paz, & Peterson, 2006; Pavonetti, Brimmer, & Cipielewski, 2002–2003; Radloff, 2008; Stainthorp & Hughes, 2000), studies in which the checklist and the outcome measures were not administered within the same school year (e.g., Harlaar et al, 2007; Hood, Conlon, & Andrews, 2008; Shatil & Share, 2003; Stainthorp, 1997), and studies in which the participants were too old to meet our inclusion criteria (e.g., Lee, Krashen, & Tse, 1997; Stone, Fisher, & Eliot, 1999; West et al, 1993). Studies were also excluded when the respondents were teachers (e.g., McCutchen et al, 2002), kindergarten children (e.g., Bulat, 2005), or the parents of school-aged children (e.g., McGrath et al, 2007).…”
