Studies demonstrating this greater susceptibility of neurobiologically responsive children to both positive and negative aspects of their environments have
implicated a wide variety of stressors and adversities, including paternal depression (67), marital conflict (68, 69), parental psychopathology (70), and overall family distress (71); of positive environmental features, including parental warmth (72) and supportive interventions (73); and of defining biological parameters, including physiological reactivity (e.g., 74, 75), differences in
brain circuitry (76), and gene polymorphisms (77, 78).
