He now regrets not pursuing this line of work at that time.Īfter a long hiatus, Roediger dived back into the world of mnemonics. “Here without much effort, without much practice, we show recall is much better using simple techniques in a standard laboratory setting,” he said. Participants using the link method doubled that, and those using the lociĪnd peg methods did even better, Roediger reported in a 1980 issue of the Journal of Experimental Psychology: Human Learning and Memory. Controls using no mnemonic recalled about five words in order. He gave study participants three lists of words to memorize in order using one of the main three mnemonic techniques. Roediger first studied the power of mnemonics several decades ago. All these mnemonic techniques rely on the power of mental imagery or visualization, the ability to imagine objects in spaces, which provides a powerful boost to remembering. In the spirit of Ricci’s memory palaces, users of the journey method envision a physical path they can’t forget - such as the walk through their houses - and place items they want to remember in spots along it. The most popular mnemonic device is the “journey” or “loci” method.

Another is the “peg” method, which establishes a series of mental pegs to “hang” a memory on. One is the “link” method, which strings together a series of images that remind users of a topic. Roediger discussed three conventional favorites among mnemonic techniques. In the 16th century, the Jesuit priest Matteo Ricci famously created the so-called “memory palace” - a physical space he could roam in his mind to retrieve information based on the spatial retrieval cues. Later, Romans trained bright slaves, known as graeculi, or Little Greeks, to memorize things for them. Mnemonic techniques go back to the days when ancient Greeks had to memorize lengthy speeches, said Roediger. Dellis, the reigning three-time US Memory Champion, helped him demonstrate to the crowd just how spectacular those feats are. Louis, has pivoted some research attention to the spectacular feats of extreme memorizers. Roediger, APS Past President and a psychological scientist at Washington University in St. Roediger and Dellis had spent the past hour revealing the secrets of mnemonic memory as part of the Bring the Family Address at the 2014 APS Annual Convention. He was going to recite the digits - all 100 - back to the audience, in order.Ī crowd never sat so silent in anticipation. After Roediger announced the 100th digit, Dellis leaned back and asked for a moment to let it all sink in. Dellis hunched over, his hands pressed over his eyes, his face a bit red with intensity. A few feet to his left, memory athlete Nelson Dellis sat in a chair absorbing each one. Roediger, III, spoke random digits at a rate of one every 2 seconds.
