“…ER involves monitoring one's emotional state and employing strategies to modify emotional experiences, typically in pursuit of a goal (Denham, 2006;Harrington et al, 2020). Children in preschool are beginning to regulate their emotions with less outside help (Holodynski & Friedlmeier, 2005), and studies have suggested that ER ability is associated with engagement in pretend play (e.g., Lindsey & Colwell, 2013). Despite these links, few causal conclusions can be drawn due to mixed results in intervention studies: some target ER-adjacent skills or provide immediate results that fade (Blair et al, 2018), and some benefit children only in specific, non-generalizable contexts (Moore & Russ, 2008).…”
