A study on video-generated multiple-choice questions revealed the cross-modal information flow mechanism in visual-linguistic models through layer-by-layer causal interventions. The results showed that visual information is mainly integrated when the model processes candidate answer options, which serve as the main textual basis for final decisions; nouns play a semantic anchoring role in modal enhancement, while verbs are more crucial in processing temporal relationships. The study also found that visual-linguistic models have difficulty reconstructing sequence information between video frames, and this vulnerability may reflect language biases related to specific temporal expressions.

From Vision to Language: Investigating Causal Information Flow in Multimodal Decision-Making
一项针对视频生成多选择题设置的研究，通过逐层因果干预视频文本注意力路径，揭示了视觉 - 语言模型中的跨模态信息流动机制。结果显示，视觉信息主要在模型处理候选答案选项时进行整合，这些选项构成了最终决策的主要文本依据；名词在模态增强中起语义锚定作用，而动词在处理时间关系时更为关键。研究还发现，视觉 - 语言模型难以重建视频帧间的序列信息，这种脆弱性可能反映了与特定时间表达相关的语言偏差。
