I feel it in my finger: Measurement device affects cardiac interoceptive accuracy
Open accessAbstract
In recent years, measures of cardiac interoceptive accuracy have been heavily scrutinised. The focus has been on potentially confounding physiological and psychological factors; little research has examined whether the device used to record objective heartbeats may influence cardiac interoceptive accuracy. The present studies assessed whether the device employed influences heartbeat counting (HCT) accuracy and the location from which heartbeats are perceived. In Study One, participants completed the HCT using a hard-clip finger pulse oximeter, electrocardiogram (ECG) and a smartphone application. In Study Two, an ECG, hard-clip and soft-clip oximeter were compared. Moderate-strong correlations were observed across devices, however, mean HCT accuracy and confidence varied as a function of device. Increased sensation in the finger when using a hard-clip pulse oximeter was related to increased accuracy relative to ECG. Results suggest that the device employed can influence HCT performance, and argue against comparing, or combining, scores obtained using different devices.

Metacognitive awareness of one's own accuracy (interoceptive insight) appears to be weakly associated with objective accuracy in the cardiac domain, although discrepancies across objective cardiac tasks have been observed.
“Metacognitive awareness of one’s own accuracy (also termed interoceptive insight) also appears to be weakly associated with objective accuracy in the cardiac domain, although again discrepancies across the objective cardiac tasks have been observed (Forkmann et al., 2016; Garfinkel et al., 2015; Murphy, Brewer, et al., 2019).”

The Study Two correlation table (presented under Discussion; page unavailable) shows mixed associations between insight and cardiac accuracy: several are nonsignificant, but the ECG insight–ECG accuracy correlation is .597. The paper compares measurement devices used for heartbeat counting, not discrepancies across distinct objective cardiac tasks. Thus it supports a variable relationship, but not the full generalization attributed to it. (LLM, conf=0.83)
Experimental — accuracy not yet measuredSelf-reported interoceptive accuracy measures (questionnaires and confidence ratings) appear to correlate with each other as well as with objective measures of interoceptive accuracy, although the cardiac perception task used appears to affect results.

Experimental — accuracy not yet measuredObjective accuracy in perceiving internal states, when explicitly aiming to do so, is distinct from attention towards interoceptive signals.
“we have recently proposed that one’s objective accuracy in perceiving internal states, when explicitly aiming to do so, is distinct from one’s attention towards interoceptive signals (Murphy et al., 2020; Murphy, Catmur, et al., 2019; Murphy, Brewer, et al., 2019).”

The Introduction discusses measures of cardiac interoceptive accuracy, and the Discussion reports how measurement devices affect accuracy. Neither section addresses whether accuracy when deliberately perceiving internal states is distinct from attention to interoceptive signals; searches for that distinction found no passage in our copy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
