Interoceptive accuracy — the objective correspondence between an individual's reported experience of internal bodily signals and those signals as measured by external physiological instruments — occupies a contested yet pivotal position in the depth-psychology corpus. The construct is most precisely articulated by Garfinkel and colleagues, whose empirical framework distinguishes accuracy from the related but non-identical concepts of interoceptive sensibility (self-reported propensity to attend to bodily states) and interoceptive awareness (metacognitive insight into one's own accuracy). This tripartite differentiation, widely cited by Khoury, Khalsa, and Herman, has become the primary scaffolding for clinical and experimental research alike. The heartbeat detection or counting task serves as the dominant behavioral operationalization, enabling quantitative comparison of subjective count against electrocardiographic ground truth. The corpus reveals persistent tensions: accuracy and sensibility are not reliably correlated and may dissociate under conditions of addiction, depression, and anxiety, challenging any conflation of felt body-sense with genuine physiological precision. Herman's work on addiction demonstrates that abstinent patients show reduced interoceptive accuracy relative to controls, while cocaine users may paradoxically show heightened sensitivity — a dissociation with profound implications for craving, relapse, and self-regulation. Craig's neurobiological account grounds accuracy in spinothalamic and insular pathways, situating it within a broader homeostatic architecture. The measurement validity of heartbeat-based accuracy scores remains actively disputed.

Interoceptive accuracy or 'the objective accuracy with which a patient can report internal sensations', can be assessed in behavioral tests such as heartbeat detection, and seems to be altered in some psychiatric conditions.
Khoury establishes interoceptive accuracy as an empirically measurable, behaviorally assessed construct distinct from related interoceptive concepts, and documents its alteration across multiple psychiatric diagnoses.

Interoceptive accuracy/sensitivity: The ability to precisely and correctly monitor changes in internal signals, such as heart rate; i.e. the correspondence between objectively measured physiological events and individuals' reported experience of them.
Herman provides the canonical operational definition of interoceptive accuracy as the objective correspondence between physiological events and subjective report, distinguishing it from self-report-based sensibility measures.
Herman, Aleksandra M., Interoception Within the Context of Impulsivity and Addiction, 2023thesis
Accuracy: Reliably discriminating interoceptive signals from noise or competing signals; correct and precise monitoring.
Khoury's glossary formalizes interoceptive accuracy as signal discrimination against noise, anchoring it to the heartbeat detection task and distinguishing it from metacognitive insight and attention quality.
Khoury, Nayla M., Interoception in Psychiatric Disorders: A Review of Randomized, Controlled Trials with Interoception-Based Interventions, 2018thesis
Abstinent patients addicted to alcohol, heroin, nicotine, or synthetic cannabinoids showed lower interoceptive accuracy compared to control subjects, yet higher interoceptive sensitivity was reported in cocaine smokers.
Herman documents a critical empirical dissociation in addiction: interoceptive accuracy is typically reduced in abstinent substance users, while interoceptive sensibility may be paradoxically elevated, undermining any simple conflation of the two constructs.

The act of sensing, interpreting, and integrating information about the state of inner body systems can be related to different elements such as interoceptive attention, detection, discrimination, accuracy, insight, sensibility, and self-report.
Khalsa situates interoceptive accuracy as one distinct facet within a broader multidimensional taxonomy of interoceptive features, emphasizing that these elements only partially overlap and likely reflect distinct neural processes.
Khalsa, Sahib S., Interoception and Mental Health: A Roadmap, 2018thesis
The act of sensing, interpreting, and integrating information about the state of inner body systems can be related to different elements such as interoceptive attention, detection, discrimination, accuracy, insight, sensibility, and self-report.
This parallel passage reinforces Khalsa's taxonomic positioning of accuracy as a distinct and only partially overlapping feature within the full interoceptive construct space.
Khalsa, Sahib S., Interoception and Mental Health: A Roadmap, 2018thesis
Impaired insight (e.g., poor confidence–accuracy correspondence on a task) … Interoceptive investigations in mental health populations might reveal evidence of … distorted physiological sensitivity.
Khalsa distinguishes impaired interoceptive accuracy from related clinical phenomena such as attentional bias and cognitive catastrophizing, positioning accuracy as one of several mechanistically independent targets for psychiatric investigation.

Impaired insight (e.g., poor confidence–accuracy correspondence on a task) … distorted physiological sensitivity (e.g., blunted or heightened magnitude estimation in response to a perturbation).
This passage underscores that interoceptive accuracy failure in psychiatric populations may reflect distinct mechanisms — including confidence–accuracy misalignment and distorted magnitude estimation — that require separate measurement strategies.

All participants performed the heart rate tracking task as an objective physiological performance measure of IA and a computerized version of the Iowa gambling task (IGT) as a validated measure of decision-making.
Sübayet al. operationalize interoceptive accuracy via heartbeat tracking and link it to decision-making capacity in addicted patients, establishing an empirical bridge between bodily signal precision and adaptive behavior.

Decreased IA in patients with addiction may fail to guide effective decision-making.
Sübayet al. argue that reduced interoceptive accuracy functionally impairs somatic guidance of decision-making in addicted individuals, connecting the construct directly to behavioral dysregulation.

Interoceptive accuracy and interoceptive sensibility in individuals with alcohol use disorder — different phenomena with different clinical correlations?
Herman cites research demonstrating that interoceptive accuracy and interoceptive sensibility are empirically dissociable in alcohol use disorder, with distinct clinical profiles and correlates.

Heartbeat awareness can be measured by asking a person to count the number of heartbeats she or he feels in objectively timed intervals of 30, 45, and 60 seconds, and comparing those numbers to real counts obtained from an electrocardiogram.
Craig describes the behavioral protocol that operationalizes interoceptive accuracy as heartbeat counting compared to ECG ground truth, grounding the construct in a specific, reproducible neuroscientific method.

The utility of including measurements such as interoceptive insight (as referred to by Khalsa and colleagues) or metacognitive awareness about interoceptive task performance (as referred to by Garfinkel and colleagues) may be a promising route for future studies.
Khoury argues that future psychiatric research should complement accuracy measures with metacognitive insight assessments, reflecting the construct's embeddedness within a larger interoceptive architecture.

Interoceptive attention tendency, a trait which Farb et al. describe as 'habitually attending to particular interoceptive signals.'
Khoury contextualizes interoceptive accuracy within a broader taxonomy by contrasting it with attention tendency, sensibility, and self-efficacy, illustrating that accuracy is one of several partially independent interoceptive dimensions.

Substance abuse further disrupts the balance between interoception and exteroception … leading to hyperfocus on external stimuli and a decreased ability to perceive internal bodily sensations.
Herman situates interoceptive accuracy deficits within a broader interoceptive–exteroceptive imbalance produced by substance abuse, suggesting that accuracy loss is part of a systemic perceptual reorganization.
