According to the study's press release:
"Participants were exposed to a variety of sights, sounds, and tactile sensations. They were then asked to listen to pure tones through headphones, look at various shades of red squares, and feel low-intensity vibrations by gripping an aluminum bar. Each set of tones, squares, and vibrations was separated by time delays ranging from one to 32 seconds.
Although student's memory declined across the board, when time delays grew longer, the decline was much greater for sounds and began as early as four to eight seconds after being exposed to them.
In a second experiment, the researchers tested participants' memory using stimuli they might encounter on an everyday basis. Participants listened to audio of dogs barking, watched silent videos of a basketball game, and touched and held objects blocked from view, such as a coffee mug. The researchers found that between an hour and a week later, students were worse at remembering the sounds they had heard, but their memory for visual scenes and tactile objects was about the same."
Our minds are wired to excel at visual and tactile memory, but not auditory memory. On a practical level, this is good to keep in mind when you are trying to commit something to memory, or help others do the same.
When you are teaching somebody, try reinforcing the concepts with a visual aid. If you want to remember something, try creating an image of it. You can do this on paper, or in your mind's eye.
Encoding information as symbolic visuals in your imagination is a common technique used by memory competition participants. Joshua Foer, author of Moonwalking with Einstein, describes how in his popular TED talk.
By understanding and navigating our minds' strengths and weaknesses, we are better equipped to fulfill our goals. When it comes to memory, most people can achieve seemingly superhuman feats by leveraging the extraordinary strengths of the human brain.
