大模型有情绪吗？研究发现其内部存在情绪表征，但缺乏生物情绪的动态机制。
Do Large Language Models Have Emotions?
- 通过分析模型内部表示，发现情绪概念有稳定编码
- 情绪表征不随情境变化，与人脑神经活动模式不符
- 未实现注意力、决策速度等多系统动态重组，不满足生物情绪特征
大语言模型是否有情绪？最近来自Anthropic的研究报告称，在Claude Sonnet 4.5中发现了情绪概念的内部表征，认为该模型具有‘功能性情绪’。我们基于生物系统中情绪的实际功能对这一结论进行评估。情绪的核心作用在于：对情境进行上下文敏感的解读，以及根据解读结果在多个系统间重新组织处理流程。该研究部分支持了第一项功能，但模型中一致且离散的情绪表征与人类情绪在神经层面具有可变性的发现相矛盾。对于第二项功能，证据不充分：尽管情绪表征影响输出，但并未引发注意力、决策速度和动机状态的动态重组，而这正是生物情绪的关键特征。最后，我们提出实现真正情绪所需的技术路径。
原文摘要 · Abstract (English)
Do LLMs have emotions? A recent paper from Anthropic reports finding internal representations of emotion concepts in Claude Sonnet 4.5, concluding that the LLM has 'functional emotions.' We evaluate this claim against what is known about how emotions actually function in biological systems. We argue that emotions serve two core functions: the context-sensitive interpretation of situations, and the reorganization of processing across multiple systems in response to those interpretations. The Anthropic findings offer partial support for the first function, though the consistent, discrete emotional representations identified in Claude sit uneasily with affective neuroscience findings that human emotion is characterized by variable rather than uniform neural signatures. On the second function, the evidence is mixed: Claude's representations modulate output without producing the dynamic reorganization of attention, decision speed, and motivational state that defines emotion in biological systems. We close by proposing what it would take for an LLM to have emotions.
