Effective recognition therefore requires not only extracting informative unimodal representations, but also modeling how temporally aligned behavioral evidence interacts across modalities. In this paper, we propose a synchronized visual-facial cross-refinement framework (SVF-CR) with pairwise multimodal evidence fusion for ambivalence and hesitancy recognition. The proposed method first extracts whole-video segment tokens and cropped-face segment tokens using the same temporal partition. The synchronized visual and facial tokens are refined through intra-modal self-attention and bidirectional visual-facial cross-attention, allowing wholevideo context and local facial behavior to mutually refine each other before evidence construction. We then construct segment-level visual-facial evidence using consistency and discrepancy modeling, followed by temporal self-attention and attention pooling. Textual and acoustic features are lightly refined through context self-attention and are fused with the enhanced visual-facial evidence at the final decision stage using pairwise evidence fusion. Experiments on the BAH (Behavioral Ambivalence/Hesitancy) public evaluation split show that the proposed synchronized visual-facial cross-refinement improves public macro-F1 over both global visual-face token fusion and synchronized evidence baselines, achieving a public macro-F1 of 0.7156.

In such settings, a person may not explicitly state uncertainty or reluctance, but may still reveal it through subtle verbal and non-verbal behaviors. Automatically recognizing these states can help interactive systems identify when a user is uncertain, resistant, or not fully committed, and can support more adaptive feedback, decision support, or intervention strategies [3] . Therefore, ambivalence and hesitancy recognition is not merely a binary classification problem, but a step toward understanding complex human intention and readiness for change in natural interactions [4] .  \nAmbivalence and hesitancy are challenging because they are often expressed through weak, indirect, and temporally distributed cues. Unlike conventional emotion categories, these states are not always conveyed by a single clear facial expression or a specific spoken phrase [5, 6] . A participant may verbally provide an answer while showing uncertainty through facial movements, gaze changes, pauses, prosodic variation, or inconsistent non-verbal behavior [3, 7, 8] . In other cases, the verbal content may appear neutral, while facial and visual behavior reveals hesitation. This makes ambivalence and hesitancy recognition highly dependent on the relationship among textual, visual, facial, and acoustic evidence rather than on any single modality alone.  \nA common strategy in affective behavior analysis is to combine multiple modalities, such as text, visual, and audio features [9, 10] . However, simple concatenation of heterogeneous modality features does not necessarily lead to better recognition.
