IDEA (2004) defines Learning Disabilities/Specific Learning Disabilities as a "disorder in 1 or more of the basic psychological processes involved in understanding or in using language, spoken or written, which disorder may manifest itself in the imperfect ability to listen, speak, read, write, spell, or do mathematical calculations." Disorders that are included under the IDEA definition are perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia. The IDEA definition states that the disorders not included result from visual, hearing, or motor disabilities, intellectual delay, emotional disturbance, or disadvantage (Specific Learning Disabilities, 2015).
LD/SLDs can affect individuals in various ways, such as affecting the ability to read, write, speak, spell, do math computations, reason, and additionally affect attention, memory, coordination, social skills, and emotional development (New to LD, 2015).
