Perceptions of ambiguous biological motion are modulated by different individual cognitive abilities (such as inhibition and empathy) and emotional states (such as anxiety). This study explored facing-the-viewer bias (FTV) in perceiving ambiguous directions of biological motion, and investigated whether task-irrelevant simultaneous face emotional cues in the background and the individual social anxiety traits could affect FTV. We found that facial motion cues as background affect sociobiologically relevant scenarios, including biological motion, but not non-biological situations (conveyed through random dot motion). Individuals with high anxiety traits demonstrated a more dominant FTV bias than individuals with low anxiety traits. Ensemble coding-like processing of task-irrelevant multiple emotional cues could magnify the facing-the-viewer bias than did in the single emotional cue. Overall, those findings suggest a correlation between high-level emotional processing and high-level motion perception (subjective to attentional control) contributes to facing-the-viewer bias.
对模糊生物运动的感知会受到不同个体认知能力（如抑制和共情）和情绪状态（如焦虑）的调节。本研究探讨了在感知生物运动的模糊方向时的面向观察者偏差（FTV），并调查了背景中与任务无关的同时出现的面部情绪线索以及个体社交焦虑特质是否会影响FTV。我们发现，作为背景的面部运动线索会影响社会生物学相关场景，包括生物运动，但不会影响非生物场景（通过随机点运动传达）。高焦虑特质的个体比低焦虑特质的个体表现出更显著的FTV偏差。与任务无关的多个情绪线索的整体编码样处理比单个情绪线索更能放大面向观察者偏差。总体而言，这些发现表明，高级情绪处理与高级运动感知（受注意力控制影响）之间的相关性导致了面向观察者偏差。
