Alex Mullen is the reigning World Memory Champion. He can memorize an entire shuffled deck of cards in 17 seconds. He can remember hundreds of random words and images. Yet, he still loses his keys on occasion.
Recently, researchers began looking into what makes people like Alex so much better at memorizing these things. But when they studied the brains of memory champions compared to those of the average human, they didn’t find anything different in the brain structure. So they ran a study to see if they could increase an average person’s memory through training. The scientists taught different groups of participants to memorize a random string of words using memory techniques. The group that used a technique called “memory palace” increased their memorizing abilities and managed to sustain their increased memory after the study.
