This paper uses webcam eye-tracking to measure decision difficulty in binary choice tasks, finding that harder choices involve more eye dwells and longer final dwells.

This paper shows that touch-devices can sensitively capture decision-difficulty through mouse-tracking and touchscreen interactions across different devices.

The paper shows that human movement trajectories reflect predicted target probabilities based on dynamic visual stimuli, indicating rapid integration of predictions and reaction time estimates.

The paper shows that theta oscillations, not alpha, predict brightness perception of flickering stimuli, with higher inter-trial phase coherence in theta linked to better brightness discrimination.
