“…There is a need for experimental work that may more precisely tease apart the mechanisms by which certain classroom processes and regulation-focused interventions may be effective for improving children's learning. Third, effect sizes from this study are small, as is typical of classroom-based research (e.g., Bulotsky-Shearer, Dominguez, & Bell, 2012;Hamre & Pianta, 2005;Reyes, Brackett, Rivers, White, & Salovey, 2012) as well as with studies of specific subsets of children from large representative samples (e.g., Adelson, McCoach, & Gavin, 2012). Fourth, although our measure of cumulative economic risk included the most robust indicators of economic disadvantage (i.e., income below poverty and mothers' education below high school; Crosnoe & Cooper, 2010), research suggests that there are other indicators related to economic risk, such as food insufficiency or household density, that may add meaningfully to our understanding of the impact of cumulative risk on children's outcomes (e.g., Burchinal, Vernon-Feagans, Cox, & Key Family Life Project Investigators, 2008).…”
