📝 摘要(中文)
近年来,多模态大语言模型(MLLMs)在情感理解中逐渐融入可解释的推理机制。然而,基于可观察情感线索的推理往往导致情感理解停留在表层的线索-标签关联,产生了“聪明汉斯效应”。当情感线索隐含、跨模态冲突、语言误导或被冗余细节遮蔽时,这种捷径变得不可靠。与此相对,人类情感的形成不仅依赖于可观察线索,还包括个体对周围事件的解读与评估。受情感评估理论启发,本文将多模态情感理解视为从感知到认知评估的过程,并提出了一个数据集、一个模型和一个基准以支持这一新范式。CogEmo-40K是一个大规模的指令调优数据集,通过感知到评估的流程构建,旨在引导基于证据的推理。CogEmo-MoE是一个紧凑的稀疏MLLM,采用交错的MoE模块进行特定评估的适应,能够在显著较小的规模下实现有效的评估推理。CogEmo-Bench引入了评估证据质量评分(AEQS),评估六个互补的评估维度下的认知-情感理解,解决了传统情感度量的局限性。实验结果表明,该范式不仅引领了CogEmo-Bench,还展现出强大的跨领域泛化能力。

📄 摘要(原文)
Recent multimodal large language models (MLLMs) increasingly incorporate explainable reasoning for emotion understanding. However, reasoning based mainly on observable affective cues can reduce emotion understanding to superficial cue-label associations, giving rise to the Clever Hans effect. Such shortcuts become unreliable when affective cues are implicit, conflicting across modalities, linguistically misleading, or obscured by redundant details. In contrast, human emotions are shaped by how individuals interpret and evaluate surrounding events beyond observable cues. Inspired by appraisal theories of emotion, we formulate multimodal emotion understanding as a progression from perception to cognitive appraisal, and introduce a dataset, a model, and a benchmark to support this novel paradigm. CogEmo-40K is a large-scale instruction-tuning dataset constructed through a perception-to-appraisal pipeline to elicit evidence-grounded reasoning across six cognitive appraisal dimensions underlying emotion. CogEmo-MoE is a compact sparse MLLM that introduces interleaved MoE blocks for appraisal-specific adaptation, enabling effective appraisal reasoning at a substantially smaller scale than typical emotion MLLMs. CogEmo-Bench introduces an Appraisal Evidence Quality Score (AEQS) to assess cognitive-affective understanding across six complementary appraisal dimensions, addressing the limitation of conventional emotion metrics that evaluate what emotion is predicted but not why it arises. Extensive experiments show that our paradigm not only leads CogEmo-Bench, but also exhibits strong cross-domain generalization. Our findings suggest that perception-to-appraisal reasoning can move beyond surface-level cue-label associations toward more reliable multimodal emotion understanding and closer cognitive alignment between MLLMs and humans.
