A higher-order theory of emotional consciousness

Open access
LeDoux, Joseph E., Brown, Richard·2017·Proceedings of the National Academy of Sciences

Abstract

Emotional states of consciousness, or what are typically called emotional feelings, are traditionally viewed as being innately programmed in subcortical areas of the brain, and are often treated as different from cognitive states of consciousness, such as those related to the perception of external stimuli. We argue that conscious experiences, regardless of their content, arise from one system in the brain. In this view, what differs in emotional and nonemotional states are the kinds of inputs that are processed by a general cortical network of cognition, a network essential for conscious experiences. Although subcortical circuits are not directly responsible for conscious feelings, they provide nonconscious inputs that coalesce with other kinds of neural signals in the cognitive assembly of conscious emotional experiences. In building the case for this proposal, we defend a modified version of what is known as the higher-order theory of consciousness.

Written from the paper’s full text.

TL;DR

The paper proposes a higher-order account of emotional consciousness, arguing that feelings are not produced by dedicated subcortical emotion circuits but by the same cortical cognitive networks that support other conscious experiences. Subcortical defensive survival circuits, such as amygdala-centered circuits, supply nonconscious inputs that shape but do not constitute emotional feelings.

Key findings

  • Conscious emotional experiences, including fear, are proposed to arise from higher-order representations in a cortical general network of cognition involving lateral and medial prefrontal, posterior parietal, and insular cortex; subcortical circuits are not directly responsible for feelings.
  • The theory modifies higher-order thought into HOROR and self-HOROR: a nonconscious higher-order representation is re-represented, and when self-information is included, an autonoetic, self-aware emotional experience results. The authors argue that self-involvement is necessary for emotion.
  • Evidence cited includes weak correlations between fear feelings and behavioral/physiological threat responses; subliminal threat studies showing amygdala activation and bodily responses without reported fear; blindsight patients showing threat responses without fear; and amygdala damage disrupting threat responses but not fear experience.
  • The paper notes that English has over three dozen words for fear-related experiences, and proposes that emotion schemas and language shape emotional experience. It also claims emotions cannot be unconscious and that one cannot be mistaken about which emotion one is feeling.

Methods

  • Theoretical/conceptual paper: develops and defends a modified higher-order theory of consciousness and extends it to emotion, using fear as the primary illustrative case.
  • Synthesizes prior philosophy, cognitive science, and neuroscience findings on consciousness, amygdala function, defensive survival circuits, memory, self, and emotion; no new experimental data, sample, or statistical analysis are reported.
  • Main analysis is argumentative: contrasts first-order versus higher-order theories, reviews evidence for nonconscious threat processing, and derives predictions, such as that damage to first-order subcortical circuits should mute but not eliminate fear.

Limitations

  • The authors state that their conclusions may not apply equally to all emotions and that fear is used as a starting point; they also state that whether fear experiences differ quantitatively or qualitatively when amygdala inputs are absent is unknown.
  • The paper is theoretical and relies on interpretation of existing evidence; it does not directly test HOTEC or self-HOROR, and the text acknowledges that consciousness in animals cannot be measured directly.
  • The text makes evident that the account depends on contested claims about nonconscious working memory and introspection, and that the evidence for subcortical phenomenal feelings is considered unconvincing by the authors rather than definitively settled.

    Lessons from fear provide general principles that can at least be used as a starting point for theorizing about many emotions.

    “Although our conclusions may not apply equally well to all emotions, we maintain that the lessons from fear provide general principles that can at least be used as a starting point for theorizing about many emotions.”

    It is possible to have the experience as of seeing something without it being there to be seen, as in hallucinations or dreams.

    The subcortical representations proposed by Panksepp and Damasio occur in humans and other mammals.

    “The subcortical representations proposed by Pankesepp and Damasio clearly occur in humans and other mammals.”
  • The authors state this as an assumption.

    Nonconscious HORs exist.

    “HOROR thus depends on the existence of nonconscious HORs.”

    The amygdala has direct connections with the GNC.

    “In addition, the amygdala has direct connections with the sensory cortex, allowing bottom-up attentional control over sensory processing and memory retrieval, and also has direct connections with the GNC.”

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.

A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
