“…The association between various measures of self-regulation and academic achievement is generally robust (see a meta-analysis of concurrent studies by Allan et al, 2014, and a review by Clements et al, 2016; see Appendix 1 for a summary research literature included hereinafter). Behavioral self-regulation has predicted children's math (e.g., Blair & Razza, 2007;Blair, Ursache, Greenberg, Vernon-Feagans, & Family Life Project Investigators, 2015;Brock, Rimm-Kaufman, Nathanson, & Grimm, 2009;Clark, Pritchard, & Woodward, 2010;McClelland et al, 2007;Ponitz, McClelland, Matthews, & Morrison, 2009;Schmitt, Geldhof, Purpura, Duncan, & McClelland, 2017) and reading skills (e.g., Becker, McClelland, Loprinzi, & Trost, 2014;Bohlmann, Maier, & Palacios, 2015;Fuhs, Nesbitt, Farran, & Dong, 2014;Lonigan, Allan, & Phillips, 2017;McClelland et al, 2007;Schmitt et al, 2017), concurrently as well as across time. However, some studies, particularly longitudinal studies, have obtained null or less robust findings (e.g., Brock et al, 2009;Clark et al, 2010;Connor et al, 2016;Duncan et al, 2007;Liew, Chen, & Hughes, 2010).…”
