BrainMATTERS SPRING|SUMMER 2021 9 To test memory accuracy in this study, the researchers created an immersive, scientifically controlled event for their participants: a 30-minute, audio-guided tour of art and other items displayed at Baycrest. Two days later, participants were asked to tell the researchers everything they could remember about the tour. The responses were recorded and then verified against the facts. Using standardized, verifiable events to test memory is an innovative approach, as scientists typically use artificial laboratory stimuli, such as random word lists, rather than real-life experiences. Alternatively, they may test participants' memory for personal past experiences, which cannot be verified. The results showed that participants' accuracy was high in both cases, though, as expected, the number of details they remembered decreased with age and time. At best, they recalled about 25 per cent of their art tour. Generally speaking, this means that we can be reassured that our memories remain accurate, even if details fade with time and age. While forgetting details is normal across all ages, there are things you can do to strengthen your memory recall today and for the future. Spaced repetition: We all know repetition improves memorization. To make repetition more effective, wait a few seconds before repeating the item you want to memorize, then wait a few seconds longer. Increasing the intervals between repetitions helps to firmly establish the memory. Retrieval practice: Practising retrieving information from your memory is even more effective than studying that information again. After you learn something, try to remember it. Then take a break and repeat. Organization: We remember information better when we mentally organize it. Try organizing your grocery list into different categories. For example, group apples, pears and oranges together in one category and garbage bags and all-purpose cleaner in another. Context matching: It's easier to retrieve information from your memory when you're in a similar context (for example, a similar place or even mood) to the one in which you learned that information. If you want to be able to remember something in a specific location, try studying or rehearsing it there. If you want something to be more memorable overall, study or rehearse it in many different contexts. Visualization: When you hear verbal information, try visualizing it in your mind — we remember information much better when we experience it with multiple senses. Research at Baycrest's Rotman Research Institute (RRI) advances our understanding of the complexity of the human brain. With a primary focus on aging and brain health, RRI scientists and other researchers across the Baycrest campus promote effective care and improved quality of life for older adults, helping them enjoy all that life has to offer as they age.
