As people suggest methods for our children with CVI to learn to read, I wondered what does the brain need to do in order to learn to read? I found a local researcher, Maryanne Wolf of Tufts University who wrote extensively about the neuroscience of reading in her book Proust and the Squid.
As it turns out, the brain needs to do quite a lot. It certainly requires a high degree of sustained visual attention, which can be problematic for many of our children with CVI.
Reading requires the whole brain including the occipital lobes, parietal, frontal and temporal lobes. The brain needs activation in both hemispheres and needs the “language areas” of the brain to be engaged and active. There are steps to reading function from decoding to understanding what is read. This reading “thing” is quite complex which is no surprise given how complex the brain is!
When we apply reading methods for our students with CVI, we need to apply methods to the child not decide that all methods work for everyone. We need to be diagnostic. What is working? Why is it working and under what conditions? Is it working at all? What can we do to improve this complex process that includes learning to use vision and to build reading skills?
No one of us serving students with CVI can know everything. We can certainly educate ourselves but will not be experts in everything. We must seek out and collaborate effectively with experts. In this case of reading, we need to partner with reading specialists as we apply any techniques for learning to read.
One size will not fit all because every brain is different and learns differently.
