Investigating the link between eye movements and dyslexia

We are exploring whether differences in time perception could cause the visual symptoms associated with dyslexia.

Fixational eye movements are involuntary, microscopic eye movements that are essential to maintain steady fixation on a single point. These movements are necessary particularly for tasks that require stable perception such as reading or viewing fine details, which is where people with dyslexia typically present abnormalities.

The purpose of this study is to investigate a potential cause of reading difficulties by examining the relationship between time perception and the microscopic eye movements that aid in maintaining focus while reading.

What does the study involve?

The study will include reading ability tests, an IQ test, and two game-like psychophysical tests. In one, participants will be asked to identify which of two stimuli appeared first, based on a short time difference. In the other task, participants will decide whether a middle bar is misaligned more toward the left or right bar. For more information please view the participants information sheet.
