“…The predictive validity of observational measures has been examined, with work establishing that such temperament indices show meaningful associations with children's psychophysiological systems (Fox, Henderson, Marshall, Nichols, & Ghera, 2005;Mackrell et al, 2014), moral development (Kochanska, Murray, Jacques, Koenig, & Vandegeest, 1996), and quality of parent-child relationships (Kochanska, Aksan, & Carlson, 2005). Observed affective traits (i.e., positive and negative emotionality) in preschoolers have been linked to maternal mood disorders (Durbin, Klein, Hayden, Buckley, & Moerk, 2005;Olino, Klein, Dyson, Rose, & Durbin, 2010), EEG asymmetries (Shankman, Tenke, Bruder, Durbin, Hayden, & Klein, 2005), serotonin transporter gene polymorphisms (Hayden, Dougherty, Maloney, Durbin, Olino, & Nurnberger et al, 2007), and the development of depressotypic cognitions and emerging internalizing symptoms in middle childhood (Dougherty, Klein, Durbin, Hayden, & Olino, 2010;Hayden, Klein, Durbin, & Olino, 2006;. Overall, observational assessments of temperament have demonstrated meaningful associations with both normal and abnormal processes, indicating their utility for developmental psychopathology research (Durbin, 2010).…”
