Most of my earlier examples of the benefits of walking while studying involved treadmills and learning a foreign language. A Stanford student named Govind writes:
I found I was able to memorize GRE words very effectively while walking [compared to sitting]. It not only made the process much more enjoyable, but since I walked outside (around Oxford [England]), I also was able to associate words with physical cues. The difference between propitiate and propitious is now inextricably linked to Cowley. (I am now a memory palace convert.)
At Berkeley, I once assigned my intro psych students to do self-experiments. One of them measured how many French words she could study before falling asleep. She tried three body positions: sitting at a desk, lying on her side on her bed, lying on her stomach on her bed. She also tried three audio environments: silence, classical music, heavy metal. Best combination: lying on stomach, heavy metal. Worst combination: sitting at desk, silence. This amused me, but I now see that the real lesson of her experiment is that she didn’t try walking. It shows how little-known the walking-helps-memorize idea is, even though the effect is easy to notice, as Govind’s story shows.
