Participants Wanted: Participants with healthy/correct vision wanted for study of eye dominance
Have you ever wondered how your brain and eyes work together to help you see the way you do at any given moment? We invite you to participate in a research project to address this question. We will measure this with a behavioural task involving simple visual stimuli.
We invite participants to participate in a research project about the neural mechanisms that underlie eye dominance. We are conducting this study to find out whether our preference for visual information from one eye over the other (eye dominance) depends on the relative precision of the eye position signal from the two eyes. This study forms a step in understanding the disease mechanisms in dyslexia. You can only participate in this study if you are healthy, right-handed and have normal or corrected to normal vision.
Eye dominance is the tendency to prefer visual input from one eye to the other. Even though our eyes seem identical, people prefer using one eye of over the other when for instance sighting. This preference can be probed in the lab with the “hole-in-card” method (Mapp et al, 2003). A distant image viewed through the “hole” appears to move if you close and open the dominant eye, alternating between monocular and binocular viewing. The mechanisms behind eye dominance are still unknown. This asymmetry is less frequent in individuals with dyslexia (Le Floch and Ropars, 2017), so understanding the mechanism of eye dominance might give us a more complete picture of this clinical condition.
Our hypothesis is that the brain prefers the eye with the more precise eye position signal.
This study is being conducted as part of a dissertation research in the School of Psychology and Neuroscience, The University of St. Andrews and is supervised by Dr. Daniela Balslev.
