The protective effects of mindfulness training

February, 2010

Mindfulness Training had a positive effect on both working memory capacity and mood in a group of Marine reservists during the high-stress pre-deployment interval.

Mindfulness Training had a positive effect on both working memory capacity and mood in a group of Marine reservists during the high-stress pre-deployment interval. While those who weren’t given the 8-week MT program, as well as those who spent little time engaging in mindfulness exercises, showed greater negative mood and decreased working memory capacity over the eight weeks, those who recorded high practice time showed increased capacity and decreased negative mood. A civilian control group showed no change in working memory capacity over the period. The program, called Mindfulness-based Mind Fitness Training (MMFT™), blended mindfulness skills training with concrete applications for the operational environment and information and skills about stress, trauma and resilience in the body. The researchers suggest that mindfulness training may help anyone who must maintain peak performance in the face of extremely stressful circumstances.

Visual perception heightened by meditation training

July, 2010

Another study confirms the effects of meditation training on visual perception.

Another study showing the cognitive benefits of meditation has revealed benefits to perception and attention. The study involved 30 participants attending a three-month meditation retreat, during which they attended group sessions twice a day and engaging in individual practice for about six hours a day. The meditation practice involved sustained selective attention on a chosen stimulus (e.g., the participant’s breath). By midway through the retreat, meditators had become better at making fine visual distinctions, and better able to sustain attention during the half-hour test, compared to matched controls. Those who continued practicing meditation after the retreat still showed improvements in perception when they were retested about five months later.

Brief meditative exercise helps cognition

April, 2010

Great news for those who crave the benefits of meditation but find the thought a bit intimidating! Adding to evidence that long-term mindfulness meditation practice promotes executive functioning and the ability to sustain attention, a small study has found cognitive benefits from as little as four sessions of 20 minutes.

Great news for those who crave the benefits of meditation but find the thought a bit intimidating! While a number of studies have demonstrated that long-term mindfulness meditation practice promotes executive functioning and the ability to sustain attention, now a small study involving 49 students has found that as little as four sessions of 20 minutes produced a significant improvement in critical cognitive skills, compared to those who spent an equal amount of time listening to Tolkien's The Hobbit being read aloud. Both groups showed similar improved levels of mood, but only the meditation group improved their cognitive scores. While this group improved on all cognitive tasks, they did dramatically better when under stressful conditions, such as provided by increasingly challenging time-constraints, and particularly in the areas of attention and vigilance. Mindfulness training, as given here, focuses on breathing, letting go one’s thoughts, releasing sensory events that distract. It should be noted that no one is suggesting four days training produces a permanent effect! But it is encouraging to think that benefits might be achieved so quickly. The training also reduced fatigue and anxiety.
