Incorporate short breaks into your learning/studying/reading, and it’s more likely that you’ll retain the material better, even several days later.
However, not just any break will do. In the study cited at the link, the breaks involved “wakeful resting” – nothing too mentally taxing (the experimenters had participants sitting in the dark with eyes closed for ten minutes). In real life I guess you could sit back and relax for ten minutes but more likely you’d be checking email, answering the phone or getting up to walk around, and maybe some of those activities would interfere more with memory consolidation than quiet sedentary relaxation.
The study’s participants had to remember short stories. I’m not sure how long the stories were. Is it good to take breaks only after shorter chunks of material, or is this strategy still effective for bigger chunks? Does overall coherence of the material matter more than length? (e.g. where you’re stopping to take your break: mid-paragraph vs. mid-sentence?) Furthermore, the stories were presented aurally; would that make a difference – hearing the material you’re hoping to retain instead of reading it to yourself?
The participants in the study were elderly adults aging normally, a refreshing change from the usual practice of using college students (undergraduates are easy to recruit; you don’t even have to pay them, just make it mandatory for them to participate in research studies to fulfill some kind of course requirement). However at some point the experiment probably will be replicated with college students to see if all the results are generalizable to younger adults too.
