Eye Movements: Voluntary or reflex-controlled movements of the eye.

Eye Tracking in Cognitive Experiments

JoVE 5421

Eye tracking as the name suggests involves tracking of eye-movements. It is a non-invasive, sensitive tool that quantifies and measures eye-movements to describe an individuals' cognitive state. An eye-movement between two fixation points is called a saccade, which is one of the fastest motor movements in our body. By observing the profiles of these eye movements, scientists can better…
