Some studies have called into question the role of developing spoken language skills in relation to developing reading skills. One study in particular demonstrated that while individuals who became deaf before developing spoken language did show a decreased ability to differentiate between the phonological properties of a language, they showed equal capability of recognizing and understanding the orthographic properties of what they were reading. In fact, compared to their hearing counterparts, the deaf individuals showed an increased rate of written word processing skills as they increased in age. Altogether, this research provided evidence contrary to the belief that spoken skills are critical to the development of reading skills, and further proposes that educational approaches should include a stronger focus on building awareness of written language forms separate from the related aural aspects.
