MEET THE SCIENTIST at HU Labor with Martin Rolfs, “Movement in the eye of the beholder. How looking shapes visual perception”
Abstract: The eyes are the Marco Polo of the human body — they travel incessantly across the visual world in front of us, curious for interesting or even insightful information. Tracking someone’s eye movements, therefore, provides insights into their perception and cognition — the eyes are indeed a window to the mind.
That eye movements are necessary for perception to occur in the first place was shown in experiments in the second half of the last century, when scientists showed that preventing eye movements (e.g., through paralysis or by stabilizing an image on the retina) leads to the rapid fading of perception within a fraction of a second.
