Research gap at a glance
- Question: Within one anxiety-selected sample, does anxiety predict better cardiac and worse respiratory interoceptive sensitivity, or does the apparent reversal disappear when both channels are measured with comparable psychophysical tasks?
- Why it matters: If the reversal is real, interoception is organ-specific in a strong sense and panic theory, which is about misread breathing, cannot lean on heartbeat data. If it is an artefact of the counting task, a large part of the anxiety-interoception literature reflects how anxious people count rather than what they perceive.
- Theme: Clinical
- Status: open
What the wiki already knows
- Panic patients and analogue panickers detect their heartbeats better than controls, and better cardiac perception predicts worse clinical outcome (Ehlers (1993), Zoellner & Craske (1999)).
- On the Filter Detection Task (FDT), moderately anxious participants were less sensitive to inspiratory loads (3.0 versus 4.0 filters, Z = -2.4, p = 0.01), replicating earlier respiratory findings (Harrison et al. (2021)).
- The counting task has a route by which anxiety raises the score without better perception: in a population that undercounts, expecting a faster rhythm yields a more accurate count; the filter task has no such route (Anxiety sensitivity, Is the heartbeat-counting task a valid measure of cardiac perception?).
- On the respiratory task, anxiety sensitivity attached to confidence ratings rather than to the detection threshold (Anxiety sensitivity).
- Measurement noise attenuates correlations but does not flip their sign, so two real findings of opposite sign would be strong evidence for organ-specificity (Is interoception domain-general or organ-specific?).
What would answer it
- Recruit low-anxiety, high-anxiety and panic disorder participants and administer the Heart Rate Discrimination Task (HRDT), a counting task and the Filter Detection Task (FDT) or Respiratory Resistance Sensitivity Task (RRST) with confidence ratings and the Anxiety Sensitivity Index, then test the anxiety by channel interaction on signal-detection sensitivity, separately from confidence and bias.

The wiki’s panic literature says anxious people read their hearts better, and Harrison et al. (2021) found that anxious people read their breathing worse. Is interoception domain-general or organ-specific? and the study page both hold two readings. Either the channels relate to anxiety with opposite sign, which is a stronger form of decorrelation than a null, or the cardiac direction is an artefact of how the counting task can be gamed by expectation and the respiratory finding is the clean one.
The awkwardness for panic theory is that Cognitive model of panic and Anxiety sensitivity are largely about misread respiratory sensation (air hunger, suffocation alarm) while the supporting evidence is mostly heartbeat tasks. Interoceptive psychopathology notes that the decorrelation finding means those cardiac scores do not speak for the channel the theory is about.
Both Anxiety sensitivity and the domain-generality debate describe the discriminating study as small and unrun: both tasks, one anxious sample. It is cheaper than the perturbation experiment in Does a general interoceptive ability appear when the body is perturbed? and would settle whether the wiki holds a reversal or a broken instrument.
