Just had a word with my son Danny whose deaf, who looked at me as if I was mad and said he "just thinks", presumeably like everyone else.He sees no difference in the way a deaf person thinks and a hearing person. He reads English, Irish and some French and German and he signs but informs me that signing varies extensively amongst the deaf community and that it's far harder to understand sign language if you can't see the person's face whose talking.When say the tone of someone's voice is expressed in a book he says he generalises that to be more like texture of their personality so he has something he can relate to, but to him thought is the same as hearing people and so is language, he just can't "hear" words but he understands their meanings in the same way.Hope this helps, it's a bit garbled.Lol
