Severe reading disability, also known as dyslexia, is one of the most common classified learning disabilities (LD) in the US (Fine, Semrud-Clikeman, Keith, Stapleton, & Hynd, 2007). Approximately 5–10% of Americans possess a reading disability (RD), which makes up 80% of LD classifications (Shaywitz, 1998; Shaywitz & Shaywitz, 2003, 2005). In community-based samples, up to 17.5% of participants exhibited a RD. According to the Nations Report Card for reading progress published by the US Department of Education in 2005, more than one-third of American 4th graders performed below the basic reading level expectations (US Department of Education). Thus, issues pertaining to reading have gained serious attention in American education.

What Is Dyslexia?

Lyon, Shaywitz, and Shaywitz ( 2003) state that:

Dyslexia is a specific learning disability that is neurobiological in origin. It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding...
