With those who experience deafness, however, they are still capable of learning language, despite not being able to hear it externally. They're still capable of reading words, and understanding their meaning. This means, that as long as their auditory cortex, within the temporal lobe, and frontal lobe of the cerebrum(responsible for speech.) are not malformed, or suffer from any other obstructions, it is likely that their inability to hear external sounds would not change the processes of these two portions of the brain, which manifest an inner monologue.

As for those who do not have an inner monologue, they typically have a more developed sense of spatial intelligence. And often see words they're reading, as opposed to say them internally to themselves. The same with other instances of internalized thought, they often see pictures, as opposed to hearing themselves talking. This may also similarly be a case for those who are deaf. As opposed to the above.

You've answered the question of the thought processes of deaf people but my main question was on people that are born deaf and blind. Those people surely can't think in pictures, they have never heard language or read a book, they haven't seen sign language. There is no language there as they can't take that information in.
