The free-energy self: a predictive coding account of self-recognition

Open access
Apps, Matthew A.J., Tsakiris, Manos·2014·Neuroscience & Biobehavioral Reviews

Abstract

Recognising and representing one’s self as distinct from others is a fundamental component of self-awareness. However, current theories of self-recognition are not embedded within global theories of cortical function and therefore fail to provide a compelling explanation of how the self is processed. We present a theoretical account of the neural and computational basis of self-recognition that is embedded within the free-energy account of cortical function. In this account one’s body is processed in a Bayesian manner as the most likely to be “me”. Such probabilistic representation arises through the integration of information from hierarchically organised unimodal systems in higher-level multimodal areas. This information takes the form of bottom-up “surprise” signals from unimodal sensory systems that are explained away by top-down processes that minimise the level of surprise across the brain. We present evidence that this theoretical perspective may account for the findings of psychological and neuroimaging investigations into self-recognition and particularly evidence that representations of the self are malleable, rather than fixed as previous accounts of self-recognition might suggest.

TL;DR

The paper proposes that self-recognition can be explained within the free-energy principle and predictive coding: one’s body is represented probabilistically as the most likely cause of congruent multisensory input, and self-representations are updated when prediction errors occur. It reviews psychological and neuroimaging evidence, especially multisensory illusions, to argue that self-recognition is malleable and not tied to a dedicated self-specific circuit.

Key findings

  • Self-recognition is framed as Bayesian inference: one’s own body, face, and voice are processed as probabilistically the most likely to be “me” because they best explain congruent multisensory signals; high-level multimodal empirical priors explain away unimodal prediction errors.
  • Three multisensory illusions—the rubber hand illusion, the enfacement illusion, and the rubber voice illusion—are used to show that self-representations are plastic: synchronous stimulation can increase the probability that another’s hand, face, or voice is “me” and decrease the probability that one’s actual body part is “self.”
  • Contextual and cultural priors modulate self-other recognition: self-related primes, masked primes, culture (Western vs. East Asian), social hierarchy, and religious/atheist differences can alter self-bias.
  • Anatomical predictions include: no unimodal area is exclusively engaged by self-stimuli; self-recognition engages multimodal regions such as TPJ, AI, IPS, and IFG; and predictable self-stimuli suppress activity (e.g., self-touch reduces SI activity; viewing one’s own face during touch reduces somatosensory cortex and IFG activity).

Methods

  • Theoretical/conceptual review, not an empirical study; no participants, sample, or new data are reported.
  • Integrates the free-energy principle and predictive coding with prior psychological and neuroimaging findings on self-recognition, including self-face, self-voice, self-body, and multisensory illusion studies.
  • Main analysis is narrative synthesis and generation of testable predictions; no formal meta-analysis or statistical modeling is reported.

Limitations

  • The paper states there is little direct evidence that predictions and prediction errors related to self-stimuli are processed anywhere in the brain, and that to the authors’ knowledge no paper has tested whether self-stimuli conform to predictive coding.
  • The paper states the theory is hard to falsify with standard neuroscientific methods because 3T fMRI BOLD signal likely reflects both prediction and prediction-error neurons, which are found in separate cortical layers but cannot be resolved; it also notes no direct test of whether the self is probabilistic and little functional evidence for multimodal integration.
  • Evident from the text: as a theoretical review, it relies on existing evidence and does not provide new empirical tests; some supporting evidence is described as consistent with, rather than direct tests of, the account.

  • The paper relies on this without support.

    There has not yet been a direct test of whether the likelihood of stimuli being accepted as part of one’s body is probabilistic, whether one’s own body is represented probabilistically as self and not deterministically, and whether recognition and ownership of others’ body parts are acquired during illusions in a manner that conforms to the predictive coding account.

    “there has yet not been a direct test of whether the likelihood of stimuli being accepted as a part of one’s body is probabilistic in nature, whether one’s own body is represented probabilistically as “self” and not deterministically, and whether recognition and ownership of others’ body parts are acquired during illusions in a manner that conforms to our predictive coding account of plasticity in”

  • Minimization of prediction errors, such as those induced by multisensory conflicts during the RHI, will update posterior probabilities and, over time, can induce changes in self-related priors.

    “This is compatible with PC inasmuch as minimization of prediction errors -such as those induced by multisensory conflicts during the RHI -will update the posterior probabilities and, over time, can induce changes in self-related priors [22].”

    From Interoceptive inference, emotion, and the embodied self (2013) · cites this paper as [22]

  • Predictive Coding as a unifying theory of brain function provides a plausible framework for understanding the cognitive basis of self-recognition.

    “However, a recent interest in Predictive Coding as a unifying theory of brain function has provided a plausible framework for understanding the cognitive basis of self-recognition [55].”
  • The self is a multimodal, hierarchical construct containing both low-level, bodily representations as well as higher level attitudes and beliefs.

    “The self is a multimodal, hierarchical construct containing both low-level, bodily representations as well as higher level attitudes and beliefs.”
  • On the predictive coding account, one's body is processed in a probabilistic manner as the most likely to be 'me', given prior knowledge about our bodies and incoming sensory information.

    “On this account, one's body is processed in a probabilistic manner as the most likely to be”
  • On a predictive coding account, these different levels of representation continuously interact, as prediction errors, when left unexplained at one level, need to be processed and eliminated at a higher level of the hierarchy.

    “On a predictive coding account, these different levels of representation continuously interact [55,56], as prediction errors, when left unexplained at one level ,need to be processed and eliminated at a higher level of the hierarchy.”

Each contradiction between two passages listed here was confirmed by an independent check.

  • Four brain regions described as three

    Minor

    The functional-anatomy discussion names the TPJ, AI, IPS and IFG-four regions-but immediately refers to them as "the three regions."

  • Face explanation both declines and increases in likelihood

    Minor

    In the binocular-rivalry example, the paper says prediction errors reduce the likelihood that the input is a face, then says they update the alternative face model so that its likelihood increases. Both statements concern the face explanation for the same sensory input.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

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.
