Key findings

• Introduces an expanded taxonomy of interoceptive processes (awareness, coherence, attention tendency, sensitivity, accuracy, sensibility, regulation) to replace loose, conflated use of ‘interoceptive sensitivity.’
• Proposes the ‘simulation map’ — a layered, relatively stable ‘as-if’ neural representation of body state, closer to interoceptive awareness than raw current sensation — as the operative construct linking predictive coding to the contemplative ‘subtle body.’
• Elaborates Seth’s predictive coding model of interoception into a dual-route regulatory framework: active inference (reduce prediction error by acting to change sensation to match priors) vs. perceptual inference (reduce prediction error by updating priors to match sensation).
• Maps modern psychological emotion-regulation strategies (suppression, distraction, reappraisal) onto active inference, and contemplative strategies (acceptance, equanimity, observation) onto perceptual inference — while explicitly flagging that classifying acceptance as a ‘bottom-up perceptual’ rather than ‘top-down cognitive’ strategy may be controversial.
• Extends Seth et al.’s (2011) presence/agency framework: presence (felt connection to the moment) can arise via perceptual inference, not only active inference as originally proposed; agency is tied specifically to overt active inference and carries risks of maladaptive reinforcement (e.g., anxious avoidance).
• Reviews seven mechanisms by which mindfulness/contemplative training may reshape interoceptive processing: enhanced sensitivity (domain-specific, not domain-general), enhanced non-reactivity (precision weighting/decentering), enhanced regulation, enhanced insight, enhanced presence and agency, increased positive experience, and embodied (autonomic/postural) effects.
• Surveys clinical applications and explicit cautions: sexual-trauma recovery (MABT), chronic pain (interoceptive exposure vs. distraction), substance use disorder, and anorexia nervosa (where bringing awareness to the body can initially worsen maladaptive behavior without skillful, trauma-informed guidance).

Limitations

• Theoretical/integrative paper, not a primary empirical study; many claims are framed as testable hypotheses awaiting evidence (see its own ‘Future Research Directions’ list).
• Acknowledges mindfulness does not reliably increase objective interoceptive accuracy (heartbeat detection) despite meditators’ self-perception, complicating simple ‘training improves interoception’ narratives.
• The mapping of Asian contemplative ‘subtle body’/energy-flow concepts onto the simulation map is explicitly presented as unresolved, not settled.

An integrative theory paper written by a working group convened at the Mind and Life Institute (April 2013) to unify neuroscience, clinical psychology, and contemplative-studies perspectives on Interoception. It takes Seth’s (2013) Predictive coding model of interoceptive inference as its scientific spine and builds outward toward mechanisms of contemplative practice and clinical application — making it the applied/clinical counterpart to Seth’s more purely theoretical piece.

The simulation map

Farb et al. introduce the Simulation map: a layered “as-if” representation of body state (cf. Damasio), continuously constructed from the integration of current sensory afferents and prior expectations. Critically, the simulation map — not raw current sensation — is proposed as the construct closest to interoceptive awareness. Only a subset of its layers is consciously accessible (the “phenomenal map” is a subset of the broader simulation map). This is offered as the scientific counterpart to the contemplative Subtle body construct (channels, chi/prāṇa, energy centers), with the relationship between the two explicitly flagged as unresolved.

Active vs. perceptual inference

The paper’s central theoretical move is splitting prediction-error minimization (already present in Seth’s framework) into two named, contrasted regulatory routes — see Active inference and Perceptual inference (interoceptive):

• Active inference: weight priors over sensation; act (behaviorally or autonomically) to make sensation match expectation.
• Perceptual inference: weight sensation over priors; update expectation to match sensation.

Modern psychological emotion regulation (suppression, distraction, reappraisal) is mapped onto active inference; contemplative strategies (acceptance, equanimity, non-interfering observation) onto perceptual inference. The authors explicitly note this classification of acceptance as “bottom-up” rather than “top-down cognitive” may be controversial — see contemplative training increase objective interoceptive accuracy? and the broader inferential? debate for related territory. Their working (untested) hypothesis: because bodies show more variance than people expect, contemplative practice broadens (de-precisifies) priors rather than sharpening them.

Presence and agency, extended

Building on Seth, Suzuki & Critchley (2011), presence and agency are recast as Presence and agency. Where Seth et al. attributed presence only to active-inference-based error minimization, Farb et al. argue presence is also reachable via perceptual inference (“effortless presence”) — broadening priors so fewer sensations register as prediction error. Agency remains tied to overt active inference and is clinically double-edged: in anxiety, agency achieved through avoidance is reinforcing but prevents disconfirmation of the feared outcome, entrenching the disorder.

Interoceptive taxonomy

Following Garfinkel & Critchley (2013) and anticipating Garfinkel et al. (2015), the paper proposes a Interoceptive taxonomy (Farb et al. Box 1) of seven partially dissociable constructs (awareness, coherence, attention tendency, sensitivity, accuracy, sensibility, regulation), arguing that collapsing them under one “interoceptive sensitivity” label produces spurious inferences — e.g., meditators’ strong interoceptive attention does not predict superior heartbeat-detection accuracy (Khalsa et al. 2008; Parkin et al. 2013). See Interoceptive sensitivity for the pre-existing wiki treatment this updates.

Mechanisms of mindfulness and clinical applications

Seven proposed mechanisms of contemplative training are reviewed (enhanced sensitivity, non-reactivity, regulation, insight, presence/agency, positive experience, embodied effects), alongside concrete clinical vignettes — sexual-trauma recovery, chronic pain, substance use, and a sharp caution around anorexia nervosa, where interoceptive attention can increase maladaptive behavior absent skillful, trauma-informed support.
