I'm a professional programmer, and I also practice math. During both, I constantly talk out loud, even for simple problems. However, when I'm around other people I suppress the talking and I feel like I lose a significant amount of clarity.
My assumption is that speaking out loud provides additional clarity because:
- You're actually speaking, so you have to utilize more parts of your brain, including to physically move your mouth, which would decrease distraction/increase focus
- You're hearing it, again utilizing more parts of your brain since you have to process external auditory signals
Whereas, the auditory simulation (essentially virtual stimulus) that the brain provides during silent thought is... not as intense as the real stimulus (speaking and hearing), thus utilizing less of the brain.
My question is not about whether thinking out loud helps you figure out a problem.
My question is can long-term frequent thinking out loud have negative effects over one's ability to think internally/silently?
And if there are negative long term effects can they be corrected in a short time by shifting your thinking back to a silent process?
