A comprehensive review of these strategies using an affective neuroscience approach indicates three distinct general routes to resilience (Fig. 1A): 1) down-regulating the negative (e.g., exposure, cognitive reappraisal) by reducing distress-related responses of the amygdala, hypothalamic-pituitary-adrenal axis, and autonomic nervous system; 2) up-regulating the positive (e.g., optimism, social connectedness) by activating mesostriatal reward pathways, which in turn can buffer the effects of stress; and 3) transcending the self (e.g., mindfulness, religious engagement) by reducing activation in the default mode network, a network associated with self-reflection, mind-wandering, and rumination. Some strategies (e.g., social support) can boost resilience via more than one pathway. Under- or over-stimulation of a pathway can result in vulnerability, such as over- stimulation of the reward pathway through substance abuse. This tripartite model of resilience-building is testable, accounts for a large body of data on adult resilience, and makes new predictions with implications for practice.
