The smallest physiological changes
In our psychophysiology lab, we measure objective, physiological changes which may occur in mental disorders.
Via eye tracking, we can record pupil size and gaze direction (Fig. above); via electromyography (EMG), we measure tension in the muscle surrounding the eye.

Participants perform simple tasks, during which their physiological responses to loud noises, mild electric shocks and other stimuli are recorded.
Eye tracking is conducted with a high-speed camera providing information on gaze direction and pupil size.
We use electromyography (EMG) to measure tension in the muscle around the eye and the acoustic startle reflex.
Moreover, we use electrodes to measure the skin conductance response on the palm of the hand.
