Dyslexia

Dyslexia affects reading at the single word level, reading fluency and rate, and spelling.  In turn, these weaknesses cause difficulties with reading comprehension and written expression.  According to the research, the major cognitive correlates of dyslexia include weaknesses in one or more of the following abilities: phonological awareness, orthographic awareness, memory, rapid naming, and perceptual speed.  Other abilities that do not require reading, such as general intelligence, reasoning, oral language, mathematics, and knowledge, are often unimpaired.  In other words, the reading and spelling difficulties are often unexpected in relation to the person's other abilities.  (WJIV Dyslexia Report Guide)
