Self-report / physiology congruence

A cheap objective-ish alternative to detection tasks: instead of asking whether someone can count their heartbeats, ask whether their reported feelings covary with their measured physiology over time. Used as the Study 2 outcome in Oldroyd et al. (2019).

Rationale

Kleckner et al. (2017) report that positive correspondence between subjective and objective arousal is associated with greater activity in the brain’s interoceptive network. The inference drawn: the more congruent a person’s self-reported arousal and their physiology, the better their interoceptive functioning. That inference is the method’s entire warrant, and it is a single study’s worth.

Procedure as implemented

Youth were fitted with a Biopac MP150 and taken through five epochs — a 3-min vanilla baseline (a minimally demanding task that holds alertness steady while equipment calibrates; Jennings et al. 1992), a 2-min talking baseline, 3-min exposure (thinking about a memory of being made angry), regulation (narrating the story to a research assistant), and re-exposure (thinking about it again). After each, participants rated anger, fear, shame, sadness and guilt on 1-7 scales, averaged into a Negative Emotional Responding score. Average SCL was computed per epoch. Both series were standardized within person and correlated across the five epochs.

Interpretive care

The measure is best understood as an index of coherence — signal-to-report correspondence — rather than of accuracy or sensibility. That is a real and under-measured construct, and its main virtue here is applicability to children, where the interoception field’s standard instruments largely fail.

But its central weakness is that it cannot separate feeling from saying. The developmental story it is used to support (social-origins-of-interoception) is that dismissive parenting teaches children not to feel their bodies. An equally consistent reading of the same data is that dismissive parenting teaches children not to admit what they feel — a demand-characteristics/display-rule effect operating entirely at the point of report. Oldroyd et al. gesture at this (“dismissing children may have an interest in downplaying their distress”) without treating it as the alternative explanation it is. Distinguishing the two would need a measure of detection that doesn’t route through self-report.
