Abigail Marshall, a founding member of the Davis Dyslexia Association International, lists the following problems that a dyslexic person might have. She cautions, however, that there is no single pattern of difficulty that affects all dyslexic persons.
She might see some letters as backwards or upside down.
He might see text appearing to jump around on a page.
She might not be able to tell the difference between letters that look similar in shape such as o,e,c.
He might not be able to tell the difference between letters that have similar shape but different orientation, such as b and p, d and q.
The letters might look all jumbled up and out of order.
The letters and words might look all bunched together.
The letters of some words might appear completely backwards, such as the word was looking like saw.
The letters and words might look okay, but the dyslexic person might get a severe headache or feel sick to her stomach every time she tries to read.
He might see the letters okay, but not be able to sound out words—that is, not able to connect the letters to the sounds they make and understand them.
She might be able to connect the letters and sound out words, but not recognize words she has seen before, no matter how many times she has seen them—each time she would have to start fresh.
He might be able to read the words okay but not be able to make sense of or remember what he reads, so that he finds herself coming back to read the same passage over and over again.
It is important to understand that when a dyslexic person sees letters or words reversed or mixed up, there is usually nothing wrong with her eyes. The problem is in the way the mind interprets what the eyes see—like an optical illusion, except this mismatch between what illusion and reality happens with ordinary print on a page.
