How to Make Memories Stick

How to Make Memories Stick

Rather than repeat something over and over in an effort to memorize it long-term, it is better to relate the new information to something meaningful, according to a new study at Baycrest Health Sciences.

For example, if a new acquaintance introduces himself as Fred, instead of silently repeating his name to make it stick, you could purposefully associate him with your favorite childhood cartoon character: Fred Flintstone. Most likely you won’t forget it later.

While previous research has shown the benefits of repetition to create short-term memories, the new findings suggest that using the word’s meaning will help “transfer” memories from the short-term to the long-term, says Dr. Jed Meltzer, lead author and neurorehabilitation scientist at Baycrest’s Rotman Research Institute.

This finding is consistent with the strategies used by the world’s top memory champions, who create stories rich with meaning to remember random information, such as the order of a deck of cards.

“When we are learning new information, our brain has two different ways to remember the material for a short period of time, either by mentally rehearsing the sounds of the words or thinking about the meaning of the words,” says Meltzer.

“Both strategies create good short-term memory, but focusing on the meaning is more effective for retaining the information later on. Here’s a case where working harder does not mean better.”

During the study, the researchers were able to pinpoint the different parts of the brain involved in creating the two types of short-term memories.

“This finding shows that there are multiple brain mechanisms supporting short-term memory, whether it’s remembering information based on sound or meaning,” says Meltzer, who is also a psychology professor at the University of Toronto.

“When people have brain damage from stroke or dementia, one of the mechanisms may be disrupted. People could learn to compensate for this by relying on an alternate method to form short-term memories.”

For example, people who have trouble remembering things could carry a pad and rehearse the information until they have a chance to write it down, he adds.

For the study, the researchers recorded the brain waves of 25 healthy adults as they listened to sentences and word lists. Participants were asked to hold the information in their short-term memory over several seconds, and then recite it back, while their brain waves were recorded.

Participants were then taken to a testing room to see if they could recall the information they had heard earlier. Through the brain scans, researchers identified brain activity related to memorizing through sound and meaning.

Next, Meltzer plans to use these findings to explore targeted brain stimulation that could boost the short-term memory of stroke patients.

The findings are published in the journal NeuroImage.
