Emotional cues and social anxiety resolve ambiguous perception of biological motion
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.
