A new study published in the PLOS ONE journal suggests that clenching the hands can improve a person’s memory.
U.S. psychologists said that clenching the right hand may help in forming stronger memories, while clenching the left hand may help in remembering those memories later on.
The scientists from Montclair State University in New Jersey studied 50 right-handed participants, who were divided into five groups and given a list of words to memorize.
The first group clenched the right hand for 90 seconds before memorizing and before trying to remember the words. The second group did the same, but with the left hand. The third and fourth groups clenched one hand before memorizing and clenched the other hand before recollecting. The last group, on the other hand, did not clench their hands at all.
The researchers found that the participants who clenched their right hand before memorizing and clenched their left hand before recollecting performed the best among the groups.
These results align with previous studies showing that clenching the right hand activates the left side of the brain. The left part of the brain is responsible for encoding memories. Clenching the left hand, in contrast, triggers the right side of the brain, which is responsible for retrieving memories.
However, scientists need more work to confirm the new claims, said Professor Neil Burgess of University College London. He suggests that the scientists should conduct further investigation using a larger sample. He also recommends using brain scanning technology to confirm and validate the claims.
