A study published in the journal Memory suggests that
Saying words out loud can help you to remember them.
Canadian researcher, Colin MacLeod, a psychology professor at the University of Waterloo discovered this study and coined it: “production effect”. Speaking something out loud results in variations of the production effect on memory. Typing something out, mouthing it, or writing it down also helps, but just not as much as speaking it loudly.
MacLeod first identified the production effect in 2010, His team tested four ways of remembering by asking students to read a list of words silently, read them out loud, listen to someone else read them and listen to a recording of their own voice repeating the words. Then the students were asked to look at a long list of words and remember which ones they’d already seen.
“Silent was the worst,” MacLeod says. “It’s a little better to hear someone else’s voice. It’s better still to hear your own voice, but it’s best to produce [the word] yourself and both hear your own voice and move your own mouth.”
Another way that vocalization improves memory is in short term memory in everyday life, such as “I turned off the stove”; saying it out loud will help you remember that and wont affect you as you leave the house wondering if your house will burn down or not.
So, lesson of the day today is repeat out loud to better your memory!
