Meditation has been shown by research to be very useful at improving mood and concentration. Now some new research by Fadel Zeidan and colleagues (published in Consciousness & Cognition, April 2nd) has shown that only a few days training in a meditation technique called "mindfulness" is enough to signifcantly improve cognitive ability.
Particularly of note were the differing results on a "computer adaptive n-back task," where participants would have to correctly remember if a stimulus had been shown two steps earlier in a sequence. If the participant got the answer right, the computer would react by increasing the speed of the subsequent stimulus, further increasing the difficulty of the task. The meditation-trained group averaged aproximately 10 consecutive correct answers, while the listening group averaged approximately one.
