Hyper-scanning and hyper-pursuit define eye movement biomarkers of anxiety disorders

The authors aim to identify and characterize eye movement profiles that could serve as objective biomarkers for differentiating anxiety disorders from depressive disorders and healthy controls. They found that patients with anxiety exhibited distinct patterns of hyper-scanning and hyper-pursuit during eye movement tasks, which were linked to increased vigilance and prediction mechanisms. These findings suggest that eye-tracking could be a valuable behavioral tool for understanding and distinguishing between affective disorders.
