As a student, in the run up to exams, I used to enjoy going out walking in the hills on my own. This approach to exam preparation probably surprised my fellow students. While other walkers that I came across probably thought I was mad because, in an age before mobile phones, they would see me talking to myself; because, as I walked, I was reciting material that I needed to learn for the next exam. This technique worked for me but I have hesitated to recommend such behaviour to my students. Now, I’ve discovered that psychologists have found that cognitive performance is improved in young adults while walking at a comfortable, relaxed speed. This is probably connected to the neurogenesis that I wrote about in my post entitled ‘Gone walking’ on April 19th, 2017.
So, as the examination season is underway in many universities, I thought I should pass on my rather eccentric approach to exam revision. No doubt, I’ll discover that I wasn’t so eccentric after all but none of us dared share such an unconventional approach to exam preparation.
For many students this is examination season and the temptation to study twenty-four hours a day is high. However, recently reported research has implied that an extra three to four hours of sleep over as little as two days can restore memories. This implies that a good strategy for exam preparation is to reduce revision in the 48 hours before an exam and sleep instead.
Researchers report that sleep helps the brain to reinforce connections between brain cells, which encode important memories, and to remove connections associated with useless information. Of course from an exam preparation perspective, this does imply that you need to have been studying during the course and hence have memories to reinforce. If you haven’t then stop reading this blog and carry on revising – if necessary, all night!
For the older folks amongst my readers who sometimes feel they are suffering from early onset Alzheimer’s, having an early night or a late morning lie-in might really restore memories.
