A group of 20 did five separate exercises – including memory, language, comprehension and listening tests – on two separate occasions, 12 days apart. Before the first session there was no preparation, but before the second participants each did a 10-minute meditation exercise. The study found that after the second session delegates showed an average improvement of 12.5% in completing the tasks.
The largest individual improvement across all the tasks was 21%, while the smallest individual improvement was 2%. Reverend Matsuyama, a Zen Buddhist priest, who conducted the meditation session, said: “It is a simple principle; if your tea cup is already filled, there is no point in pouring more tea in it".
