“…Those constructs were coded, by independent groups of coders, in multiple naturalistic, carefully scripted, developmentally appropriate contexts that had been designed to elicit a variety of emotions, behaviors, and interactions within the dyad (e.g., parent is busy while child has free time, snack time, parent and child play with toys or complete a craft project, child cleans up toys, parent and child open gifts together). Notably, all of the reported coding systems have been used extensively in our laboratory including the systems for the parent’s and the child’s expressed affect (e.g., Kochanska et al 2007), parent–child MRO (e.g., Kochanska et al 2013), and the parent’s power assertion (e.g., Kochanska et al 2008). Overall, each parent–child dyad was coded in 185 min over the repeated assessments (65, 60, and 60 at 4.5, 5.5, and 6.5 years).…”
