Infrequent panickers demonstrate superior interoceptive accuracy, accurately perceiving their heartbeats. This enhanced perception is linked to higher self-reported anxiety, not physiological arousal.

Area of Science:

  • Psychology
  • Psychophysiology
  • Anxiety Disorders

Background:

  • Psychophysiological models suggest panic involves heightened attention to physical sensations.
  • Interoception, the awareness of internal bodily cues, is central to these models.
  • Understanding interoceptive accuracy in panic is crucial for treatment development.

Purpose of the Study:

  • To investigate the relationship between physiological arousal, subjective anxiety, and interoceptive accuracy.
  • To compare interoceptive accuracy in infrequent panickers versus nonanxious individuals.
  • To examine the influence of caffeine and safety information on interoception.

Main Methods:

  • A mental heartbeat tracking paradigm assessed interoceptive accuracy.
  • Participants included infrequent panickers and nonanxious controls.

  • Caffeine ingestion with varying safety information was administered.

    • Main Results:

    • Infrequent panickers exhibited significantly higher interoceptive accuracy than nonanxious participants.
    • Physiological arousal changes did not correlate with heartbeat perception accuracy.
    • Increased self-reported anxiety levels were associated with superior interoceptive performance.

    Conclusions:

    • Interoceptive accuracy may be heightened in individuals prone to panic.
    • Subjective anxiety, rather than physiological arousal, appears linked to better interoception in this context.
    • Findings challenge some assumptions of psychophysiological panic models and highlight the role of anxiety.
