How does this memory practice work?

Go ahead and skip around. What I want to talk about is the memory/learning technique they are using.

I don’t want to discuss if it’s real or not, but I believe there is a little more to it than what they showed on tv. For the most part I believe it’s legitimate. He does mention, that it’s not really useful information unless you review it, but I believe it could be a good additional tool to learning.

So my big question is, aside from what they showed in that episode. Besides, just relaxing, allowing yourself to absorb the material, and kind of how to skim the pages. What else do you believe Derren told that man to get him to absorb the material?

I noticed he might have used some mnemonic devices. Also, by using some tests to help build his confidence, opened the man up more to believing in the system.

So what do you think, I missed from the episode? What do you think happened behind the scenes?

Again, this is based off the assumption this works, so no talk about set-ups or scripted events.
