Eye Tracking

Eye tracking is a noninvasive method in psychology and neuroscience research that measures eye movements to understand how people process information. A device uses infrared light to capture the reflection off the eye, which then determines where the eye is looking and for how long, and how attention changes in response to stimuli. The camera also tracks pupil dilation and blinks. Eye tracking can provide insights into cognitive processes like attention, perception, and decision-making — and helps researchers understand how people react to stimuli.
