Don't stop fidgeting.
An emerging body of research suggests that keeping your hands busy with a desk toy can improve cognitive performance and reduce stress, Sue Shellenbarger writes for the Wall Street Journal.
Scientists are studying the ways physical movement and your environment can influence your cognitive functioning in a new field called "embodied cognition."
Frank Wilson, a neurologist and author of a book on the subject, says engaging with the physical world can be a powerful way to boost brain power. "The hand can operate as a director of consciousness—a tool or agent for the mind in achieving a mental state in which people will be able to get the outcome they want," he says.
For instance, in a series of studies published last year in Psychological Science, researchers from Princeton University and the University of California, Los Angeles examined how note-taking styles influenced cognition. According to the studies, students who took lecture notes by hand—rather than on a computer—retained more information and provided better answers to abstract questions.
Another recent study in Psychological Science found that children who often play with blocks have improved scores on tests of spatial reasoning.
Psychologists are now taking their studies outside the classroom to see how common workplace distractions—such as desk toys—can improve mental performance.
