Dyslexia, ADHD and Eye-Tracking 2 Using Eye-Tracking we want to see, if there are differences in the visual patterns between children suffering from Dyslexia and/ or ADHD (Attention- deficit/hyperactivity disorder and normal children.

Our questions:

How can we use Eye-Tracking to discover visual patterns in children

What stimuli could be interesting (reading, pictures etc.)
