Delineating physiologic defensive reactivity in the domain of self-report: phenotypic and etiologic structure of dispositional fear.

Psychological medicine - 1 Jun 2012

Kramer M D, Patrick C J, Krueger R F, Gasperi M

Abstract excerpt

BACKGROUND: Individual differences in fear and fearlessness have been investigated at their extremes in relation to markedly different forms of psychopathology--anxiety disorders and psychopathy, respectively. A documented neural substrate of fear-related traits and disorders is defensive reactivity as reflected in aversive startle potentiation (ASP). METHOD: The current study extended prior work by...
