Training the Brain
People who can accomplish unbelievable tasks, such as memorizing thousands of random numbers in under an hour, state that they just have normal brains. Some memory superstars compete in Olympic-like World Memory Championships. These mental athletes, or MAs for short, can memorize names of dozens of strangers in a few minutes or any poem handed them. Ed Cooke, a 24-year-old MA, explains they see themselves as participants rescuing the long-lost art of memory training. These techniques existed not to recall useless information, but to cut into the brain basic text and ideas.
A study in the journal Nature examined eight people who finished near the top of the World Memory Championships. The scientists examined whether their brains were fundamentally different from everyone else's or whether they were simply making better use of memorizing abilities we all possess. They put the MAs and control subjects into brain scanners and had them memorize numbers and photographs. The result surprised everyone. The brains of the MAs and those of the control subjects were indistinguishable. On every test, the MAs scored in the normal range. However, when the scientists examined what part of the brain was used during a memory activity, they found the MAs relied more heavily on areas in the brain involved in spatial memory.
MAs offer an explanation: anything can be fixed upon our memories and kept in order by constructing a building in the imagination and filling it with pictures of what needs to be recalled. Dating back to the fifth century, the building is called a memory palace. Even as late as the fourteenth century, when there were copies of any text, scholars needed to remember what was read to them. Reading to remember requires a different technique than speed reading. If something is made memorable, it has to be repeated. Until relatively recently, people read only a few books intensively (细致地) again and again, usually aloud. Today we read extensively, usually only once and without continuous focus.
So the great difference is the ability to create impressive pictures in mind and to do it quickly. Using memory palaces, MAs create memorized pictures. For example, recombine the pictures to form unforgettable scenes such as the ways through a town. One competitor used his own body parts to help him memorize a 57,000-word dictionary.
Anyone who wishes to train the mind needs first to create fantastical palaces in the imagination. Then they should cut each building into cubbyholes for memories. In a short amount of time, they will notice improvement with remembering things. To keep the skill sharp, MAs deliberately empty their palaces after competitions, so they can reuse them and they recommend that beginners do the same.
