Evidence from high-credibility research indicates that profoundly deaf individuals, particularly those born without hearing, typically experience internal thoughts as visual representations, sign language signs, or written words rather than auditory language 2 3. Because they lack access to sound, their cognitive processes are shaped by their preferred communication styles 2. Research suggests that those fluent in sign language often report thinking in signs 8 10, while others may visualize pictures, scenes, or conceptual images 3 7. Brain imaging studies support this, showing that skilled deaf readers use the temporal lobe for visual processing of text rather than the auditory-phonetic regions used by hearing readers 4. While experts caution against over-generalizing all deaf students as purely visual learners in pedagogical contexts 1, the consensus remains that their primary thought processes are purely visual and conceptual 5 6.
