Cognitive conceptualizations of panic require both the experience of arousal symptoms and their catastrophic interpretation. The tendency to interpret arousal symptoms as threatening is known as anxiety sensitivity AS, but it is unclear if increased vigilance, greater physiological reactivity, or enhanced perception are responsible for reported physiological symptoms. Each of these mechanisms has been empirically supported in clinical, but not nonclinical, populations. The current investigation examined the ability of AS, body vigilance, cardiovascular reactivity, and interoceptive acuity to predict fearful responding to a 35 CO2 inhalation in a nonclinical population.
