Several companies sell practice tests to massage therapists and massage-school graduates, with the promise that the tests will help them pass licensure tests like the Massage & Bodywork Licensing Examination and the National Certification Exam for Therapeutic Massage & Bodywork.

Now, researchers from Kent State University say practice tests really do improve memory.

“Although most people assume that tests are a way to evaluate learning, a wealth of research has shown that testing can actually improve learning,” according to two researchers from Kent State University, in a university press release.

“Taking practice tests, particularly ones that involve attempting to recall something from memory, can drastically increase the likelihood that you’ll be able to remember that information again later,” said Dr. Katherine Rawson, associate professor in Kent State’s Department of Psychology.

“Why Testing Improves Memory: Mediator Effectiveness Hypothesis,” is running in the Oct. 15, 2010, issue of the journal Science.
