Davis Research Studies

kooshbook301wThe Davis Dyslexia Correction program was developed by Ronald Dell Davis from independent experimentation and research, beginning in the early 1980’s. Davis, who was himself severely dyslexic, had discovered a simple mental technique that radically improved his ability to focus on print. Through clinical experience working with dyslexic adults and children, Davis and his colleagues improved and refined the methods over time.

In 1994, after working with more than 1,000 clients, Davis published the first edition of The Gift of Dyslexia, detailing his methods and the theory behind them. Since that time, hundreds of professionals have received advanced training in Davis methods, and licensed Davis Facilitators have collectively worked with more than 20,000 clients.

In the years since, many scholars have studied the implementation and effectiveness of Davis techniques. Below is a summary of various studies which have been published in peer-reviewed research journals, presented as conference papers, or submitted as academic dissertations.
