What are the long term effects of reading and talking out loud and while you can't hear the actual sound?
Reading aloud increases your memory retention via the the production effect. But that increase in retention is based upon a self referential auditory input. If you remove that characteristic it will not yield the same results.
This makes me wonder if cutting yourself off from that auditory input while still saying the words out loud has any negative impact on memory retention or any other aspects of the brain.
Are you disassociating the way your brain makes a connection between the spoken speech and the expected auditory input you would normally associate to it? Would making this a continual process have detrimental long term effects on your brain creating a mild form of auditory processing disorder?
Or would it yield positive results in the respect that you would be training your brain in such a manner to essentially "think harder" during this process, thereby increasing memory retention?
