Interoception, conditioning and fear: The panic threesome

The present article aims to illustrate and review evidence on how associative learning involving interoceptive stimuli (interoceptive conditioning) can lead to changes in physiological, emotional, and perceptual outcomes. We first outline a functional perspective on Pavlovian conditioning and provide a general introduction and historical background on interoceptive conditioning as a special instance of Pavlovian conditioning. Next, biological and learning accounts of panic disorder are discussed, followed by an analysis of which stimuli and responses may be most promising to model learning that is relevant to panic disorder. Finally, studies on interoceptive fear conditioning with respiratory stimuli are reviewed and discussed, and future directions are outlined.status: Published onlin
