In the article, it urges to reader to notice what things you remember and how. So, as you do when you have nothing to lose, I tested it out.
First, I analysed what things I remember most. In general, my memory is good, and I can remember things quite easily - if I'm paying attention. So there is:
One - be sure you give your full attention.
Next, I noticed that I remember things most when I see a picture or what I read/hear makes me imagine things in my head. To this day, I can recall outfits that my friends wore on nights out five years ago, because I have them pictured in my head from all the photos I took back then. I also remember what our design Tutor was telling my friend in tutorials a couple months ago because I visualized what he said, even though it did not concern my work at all. And yet, when tried to study, I couldn't remember a sentence I had read only a moment earlier. In the other two successful occasions, I noticed, there was visualization.
Two - Visualize
These two points I tried my best to incorporate in my studying, of which I had an exam today, might I say. I remembered things MUCH better than usual, even more so considering the time frame.
The method I employed was the following:
I had a program of 12 Lectures with around 3 Architectural manifestos each, almost all by different Architects. As I moved from manifesto to manifesto, I pictured in my head a building/plot for each manifesto, with the architect/s who wrote it by the entrance. As I read along, I pictured things that corresponded to what I was reading. The weirder and more memorable it is, the better.
At the end, I drew a map of what became a couple of roads with all the manifesto buildings within it. I remembered each and every manifesto, and could recall most of what I read, especially those I had time to go over in depth for a second time. The key in my case was strong visual connections.
So if you want a good memory, think about it, what makes you remember?
