Interoception

Interoception has been defined in many different ways.¹ Cardiac interoceptive accuracy (the accuracy of peoples’ perception of their own heartbeat) has been studied in psychiatric conditions, with some evidence suggesting that this perception is reduced in people with psychosis, but not people with depression or anxiety.¹ The study outlined on the slide suggested that breathing interoceptive accuracy may be impaired in people with anxiety.²
