Does PR work?
I think I got an answer to this Question, I just saw the report and I would say that reading speed is actually about the speed information input into the brain and process as well, so for normal reading, information is inputing and PROCESS at a rate of 7 +/-2 bit/ sec(conscious, going through primary visual cortex)), and for PR information is going in AND PROCESS in the brain at a rate of 10 million bit/sec(sub-conscious part),
this already answer the Question. So assuming include the actual activation, for normal reading information is inputing at a rate of 7 +/-2 bit/ sec(conscious, going through primary visual cortex)), but now, for PR, instead of information inputing, there are information Outputting at the same time(40 bit/sec I think), because the brain got the whole book already. So this kind of experiment already invalid, firstly, one is inputing and one is outputting.... secondly, reading speed is actually about the speed information input into the brain and process.
So, if you need to good experiment, you should be finding the part of brain where its show most active, and not how fast you read.
