Make fists during and after an important meeting (discreetly, of course) and you may come away with more details afterwards – but only if you made a fist with your right hand during the meeting and the left after it, that is.
According to a study by Montclair State University in the US, participants who clenched the fingers of their right hand into a fist prior to memorising a list of words and then the left during recollection performed the best. They were compared to groups who did not make fists at all or did so in a different sequence.
Researchers claim that making a fist activates specific brain regions that are associated with episodic memory formation. For instance, the right hand activates the brain’s left hemisphere for pre-encoding, which helps form a stronger memory of an event or action. The left activates the brain’s right hemisphere for pre-recall, which supports better recollection.
