@thatrelatablestudent: EXPLANATION: A 2013 study led by Ruth Propper and published in PLoS ONE found that clenching the right hand can aid in memory formation and clenching the left hand can improve memory recall. The research suggests that these movements activate specific brain regions linked to memory processing, based on the theory of hemispheric encoding retrieval asymmetry, which associates the left and right hemispheres of the brain with different memory-related functions! https://medicalxpress.com/news/2013-04-clenching-memories-left-recall-words.html https://www.eurekalert.org/news-releases/493449) https://sg.news.yahoo.com/clenching-hands-fists-boost-memory-study-080511318.html https://www.thenakedscientists.com/articles/science-news/hand-clench-improves-memory
