Approximately 80% of reading difficulties among U.S. students and adults are linked to weaknesses in underlying cognitive skills. Many individuals with reading difficulties including those diagnosed with dyslexia experience inefficiencies not only in auditory processing, but also in visual processing, memory, and attention (Bacon & Handley, 2010; Shaywitz; Vidyasagar; Fostick). When these foundational systems are under strain, reading becomes effortful and slow.
