Techniques include moving the focus of attention around the body and observing sensations that arise-the so-called 'body scan'. A secular practice, it is said to help people recoginse and overcome negative thoughts.

Some participants went through a brief mindfulness mediation training program, for 25 minutes for three consecutive days, the individuals were given breathing exercises to help them monitor their breath and pay attention to their present moment experiences. A second group of participants completed a matched three-day cognitive training program in which they were asked to critically analyze poetry in an effort to enhance problem-solving skills.Following the final training activity, all participants were asked to complete stressful speech and mathemnatical tasks in front of stern-faced evaluators. Each individual reported their stress levels in response to stressful speech and mathematical performance stress tasks, and provided saliva samples for measurement of cortisol, commonly referred to as the stress hormone. The participants who received the brief mindfulness mediation training reported reduced stress perceptions to the speech and mathematical tasks, indicating that the mindfulness mediation fostered psychological stress resilience.
