Attributed to the Greek poet Simonedes of the 5th century, the method of Loci or the 'memory palace' has become popular in modern fiction through novels such as Hannibal, and T.V series like Sherlock Holmes. The method is unbelievably potent compared to traditional rote memorisation, and with a little work upfront, will allow you to perform almost unimaginable feats of the mind.
How Does It Work?
The basic premise behind the method of Loci is that our short-term memory is near useless, and is on average only able to hold 7 numbers for a short amount of time. Where humans' short-term memory falters, our spatial memory more than makes up for!
Imagine an Item in Your House...
It can be anything. A wallet, your favourite pen, a DVD of a movie you love. Whatever it is, I bet that you have a pretty good idea of where to find it. This is because the area of our brain that deals with spatial memory is far more capable than our short-term memory.
How Can I Use This?
Simple. Take whatever it is that you want to remember, and in your mind physically walk around a space that you are familiar with. The order of the route needs to be obvious, so I would recommend deciding on a system before you begin, such as walking clockwise around a room before moving on to the next one. Once you've decided on your route, pick 5-10 locations on the journey that stand out to you. It could be a table, or your T.V., just make sure it's an obvious location and not just a random spot in the room.
Place Your Items!
Now you have your route, imagine yourself walking on this journey. At each location on the way you see a different item that you would like to remember (let's say a shopping list). At the first location, you imagine eggs have been smashed all over it, creating a huge mess! At the second location, someone has spilled gallons of milk; it's leaking through the floorboards! You complete this process for the entirety of your list, and when you want to recall this information you just retrace your steps in your mind and you will remember your items.
You might be wondering how to apply this to a deck of cards. This is where the PAO or Person, Action, Object system come into play.
