Which psychologist posited that dyslexia resulted from a difference in brain function rather than damage?

The idea that dyslexia arises from a difference in brain function rather than damage is notably associated with Dr. Samuel Orton. He was a pioneering figure in the study of reading disabilities and specifically dyslexia. Orton's research in the early to mid-20th century focused on understanding how certain neurological variations affect reading abilities. He proposed that dyslexia is a learning disability stemming from atypical brain development and function, rather than as a result of brain damage or injury. His work laid the groundwork for recognizing that dyslexia is related to difficulties in processing linguistic sounds and symbols, contributing significantly to the understanding of the condition.

This viewpoint marked a shift away from earlier perspectives that may have emphasized more structural or physical causes of learning disabilities. Today, Orton's theories continue to influence educational practices and interventions for individuals with dyslexia, reinforcing the notion that with the right support, students can learn differently and succeed in literacy despite their challenges.
