Dyslexic adults can learn from repeated stimulus presentation but have difficulties in excluding external noise.
We examined whether the characteristic impairments of dyslexia are due to a deficit in excluding external noise or a deficit in taking advantage of repeated stimulus presentation. We compared non-impaired adults and adults with poor reading performance on a visual letter detection task that varied t...
