LLM emotion vectors capture only the computational functional structure of valenced self-assessment, not the organismic grounding (existential stake) that Level 4 theories require

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Functional emotion vectors provide the strongest current evidence for Level 2 information integration, self-modelling, and metacognition indicators in LLMsclaim0.842
  Interprets the Sofroniew et al. findings within the Level 2 indicator table.
• We hypothesize that persistently active emotional state representations exist in LLMs but may be missed by standard probing methods.hypothesis0.802
  Open hypothesis from the Anthropic paper that motivates this work
• Are LLM emotion states encoded only selectively in token positions where they are operative, or in a more complex non-linear manner?question0.793
  Question raised by Anthropic and partially addressed by this paper's persistence evidence
• Emotion features in LLMs are genuinely more persistent than variance-matched random features, indicating stateful emotional encoding beyond autoregressive dynamicsclaim0.786
  Central interpretive claim of the paper supported by multiple convergent analyses
• Emotion geometry in LLM activationsconcept0.786
  Emotion emerges early, peaks in middle layers, sharpens with scale, and persists across tokens in LLM activations per Zhang & Zhong 2025
• Anthropic Interpretability Team: 171 emotion vectors causally influence behavior; performing vs having functional emotion representation are measurably differentfinding0.784
  Cited as activation-level support for the performing care vs having care distinction the battery detects behaviorally
• When LLMs produce experience claims under self-reference, is this sophisticated simulation or genuine self-representation, and how would we tell the difference?question0.780
  The core interpretive question the paper narrows but cannot definitively answer
• In intermediate regimes of scale or layer depth, LLMs may linearly represent features at intermediate levels of abstraction such as 'accurate factual recall' or 'close association' rather than abstract truthclaim0.779
