Adolescents assigned to a mindfulness meditation program appeared to have improvements in memory in a recent study.
“These results are consistent with a growing body of research in adults that has found mindfulness meditation to be a helpful tool for enhancing working memory capacity,” said Kristen E. Jastrowski Mano of the psychology department at the University of Cincinnati, who coauthored the new study.
The researchers randomly divided 198 public middle school students into three groups: mindfulness meditation, hatha yoga or a waitlist. Most students were female, ages 12 to 15, and from low-income households that qualified for reduced-cost lunch.
Before the study began and after it ended, the students completed computer-based memory assessments and reported their stress and anxiety levels via questionnaires.
The meditation and yoga groups met for 45 minutes twice a week, for four weeks. In addition, students logged their home practice in journals that were collected each week.
Two trained mindfulness instructors led the meditation group in breathing techniques, formal meditation and discussion using written scripts with instructions on sitting posture, breathing and wandering thoughts.
Students were encouraged to take CDs with meditation audio recordings and use them for 15 to 30 minutes daily at home.
The yoga sessions were structured similarly, with trained instructors focusing on breathing, yoga poses and discussion. The kids in this group were also encouraged to practice at home daily using a DVD with yoga lessons.
Memory scores increased in the mindfulness meditation group by the end of the study, while they did not change in the yoga or waitlist groups, the authors reported in the Journal of Adolescent Health.
