I've been wondering how a person would be affected if brain activity that is normally done automatically and unconsciously in a normal human being has to be done consciously by him, or vice versa.
For example, I have seen videos of mathematical savants where they describe their mental mathematical calculation process to be unconscious rather than conscious. They would say things like, "I see many colorful shapes and colors, then suddenly I know the answer to the equation." Whereas for the average person, calculating math mentally is a conscious activity.
What difference does it make if a thought is processed consciously or unconsciously? Would the brain scan look different?
Also, I'd like to read more on this topic, but don't know how to go about searching on the internet because I don't know what the topic is called. Would be very helpful if you could suggest readings or topics I can search for. Thank you!
