Researchers at the University of California at Davis found that participating in meditation actively improves our attention. As part of the study, two different participant groups went on a three-month meditation retreat. In addition to meditative training, participants also performed tasks like sitting at a computer and watching a series of lines appear on the screen. Participants were instructed to click the mouse when they saw a shorter line appear. The study found that as the retreat wore on, participants were able to better distinguish the difference between the longer and shorter lines, showing an improvement in attention. For some participants, their attention continued improving nearly six months after the retreat had ended.
