Does maturation help with reading?

The amount of required reading increases each year for children in school. A proficient reader can usually handle those increases. But for people who are spectrally sensitive, the obstacle to efficient reading is always them. It doesn't change. Their skills, the length of time they can read, and their efficiency do not improve as they mature. No matter how much they try to work on their reading, they can't improve. (Helen Irlen)
