Dyslexia
Dyslexia is a very broad term defining a learning disability that impairs a person's fluency or comprehension accuracy in being able to read, and which can manifest itself as a difficulty with phonological awareness, phonological decoding, orthographic coding, auditory short-term memory, or rapid...

Orton's interest in learning disabilities stemmed from his early work as a pathologist in Massachusetts

, where he worked with adult patients with brain damage. This led him to study why some children with apparently intact neurological functioning have language disabilities. In 1919, Orton was hired as the founding director of the State Psychopathic Hospital in Iowa City, Iowa, and chairman of the Department of Psychiatry at the University of Iowa College of Medicine. In 1925, Orton set up a 2-week mobile clinic in Greene County, Iowa to evaluate students referred by teachers because they "were retarded or failing in their school work." Orton found that 14 of the students who were referred primarily because they had great difficulty in learning to read, in fact had near-average, average, or above-average IQ scores.

Orton's study of reading difficulties in children led him to hypothesize that these individuals have failed to establish appropriate cerebral organization to support the association of visual words with their spoken forms.. He termed this difficulty strephosymbolia
Strephosymbolia
Strephosymbolia was first coined in 1925 by Samuel Orton as being an answer to the implications the term word blindness makes. Specifically this new word was created to make a distinction between itself and word-blindness, but no reasons are given for what these distinctions arise from, or what...

, meaning "twisted symbols". This term stemmed from Orton’s observation that many of the children he worked with tended to reverse letters or transpose their order. Orton also reported that some of his research subjects could read more easily if they held pages up to a mirror, and a few were rapid mirror writers.

Working in the 1920’s, Orton did not have access to modern brain scanning equipment,
but he knew from his work with brain damaged adults that injuries to the left
hemisphere produced symptoms similar to those he observed in children. Many of the children Orton studied were also ambidextrous or had mixed handedness. This led Orton to theorize that the children's reading problems stemmed from the failure of the left hemisphere to become dominant over the right. Some of Orton's theories about brain structure and organization would later be confirmed by modern brain researchers, such as Dr. Albert Galaburda, who compared the brains of deceased dyslexic and non-dyslexic adults in the late 1970s.

Dr. Orton’s key contribution to the field of education was the concept of “multisensory” teaching–integrating kinesthetic (movement-based) and tactile (sensory-based) learning
strategies with teaching of visual and auditory concepts. Dr. Orton wanted a way to teach reading that would integrate right and left brain functions. He was influenced by the work of fellow psychiatrist Grace Fernald

, who had developed a kinesthetic approach involving writing in the air and tracing words in large written or scripted format, while simultaneously saying the names and sounds of the letters.

Later, Orton began working with psychologist Anna Gillingham, who introduced a systematic and orderly approach of categorizing and teaching a set of 70 phonograms, single
letters and letter pairs representing the 44 discrete sounds (or phonemes) found in
English. In the years since Dr. Orton's death in 1948, his name has come to be strongly associated with the Orton-Gillingham

teaching method, which remains the basis of the most prevalent form of remediation and tutoring for children with dyslexia, or dyslexia-like symptoms, such as reading disabilities.
