“…Various models of child temperament propose both reactive traits (e.g., automatic behaviors and unregulated fear) and effortful or active traits (e.g., self-regulation abilities and purposeful attentional focus) as components of developmental paths 11 leading to psychopathology (Derryberry & Rothbart, 1988;1997;Kochanska, Barry, Jimenez, Hollatz, & Woodard, 2009;Lonigan et al, 2004;Muris & Ollendick, 2005;Rothbart, 1989;Rothbart, Ahadi, & Hershey, 1994;Rothbart, Posner, & Hershey, 1995). A study involving a Dutch population-based sample of adolescents found that predispositions toward low effortful control (i.e., tendencies to voluntarily inhibit a dominant response in order to perform a subdominant but more adaptive response) magnified the effect of fearfulness on internalizing problems and the effect of frustration on externalizing problems in adolescents (Oldehinkel, Hartman, Ferdinand, Verhulst, & Ormel, 2007), and effortful control and negative affect were associated with familial loadings for both internalizing and externalizing psychopathology (Ormel et al, 2005). In the next two sections, we describe the regulation liabilities in greater detail from a developmental perspective.…”
