“…Recent studies have found mixed evidence regarding the associations between dosage of preschool and socioemotional skills. A set of studies, for example, have found that more hours a week in preschool can have adverse effects in a range of socioemotional outcomes that are related to self-regulation (Huston, Bobbitt, & Bentley, 2015;Loeb, Bridges, Bassok, Fuller, & Rumberger, 2007;McCartney et al, 2010;Skibbe, Connor, Morrison, & Jewkes, 2011).
