… I do find “sub vocalization” to limit my speed of calculation. When I write “sub vocalization” I mean the concious saying of the number as if you were actually using your throat and tongue AS OPPOSED TO looking at an MRI that may very well show the same areas lighting up. Subvocalizing the extra syllables is often quite a bit slower than the actual calculation.
When reading “fiction”, no requirement for retention or consideration (suspension of disbelief), it seems a lot faster and more pleasant not to chew on the words in my experience. This isn’t the technique of speed reading in any sense but I do find not reading as if the text was spoken word an entirely different experience.
When reading math I tend to chew on anything I can get my teeth on until it’s nice and mushy but I am trying to understand rather than memorize.
I have never had any success with the technique called “speed reading” but I have found techniques such as skimming for note taking is quite helpful.
My understanding of text memorization from reading and watching videos suggests to me that there is a significant amount of linking, visualization, localization, backchaining necessary for quick successful memorization. It would suprise me if subvocalization would be on the critical path of that process. It may even be necessary to the memorization process but I haven’t practiced enough to form an opinion. Someone should ask someone like Ron White his opinions on subvocalization as he seems to have put a fair amount of effort into the skill of text memorization.
… So while the techique that is pandered as speed reading may be pretty much useless there are grains of salt within it that appear useful in some discrete instances. I suppose that is why people are willing to accept it as true. Good lies are often constructed in this manner.
It is the grains of salt that I am mostly interested in. The magic eye scanning, hundred percent retention with full comprehension without actual mental effort part can go on the pile with the “you can change your body type” and “anyone can look like arnie scharzenburger if they just try hard enough”.
