When Dr. David Servan-Schreiber was diagnosed with brain cancer, it changed his life. Confronting what medicine knows about illness, the little known workings of the body's natural cancer-fighting capacities, and his own will to live, Servan-Schreiber found himself on a journey from disease and relapse into scientific exploration, and finally to health.
Em uma conferência, ao explicar para a platéia a forma de controlar o estresse, o palestrante levantou um copo com água e perguntou:
Our vision is to create a commercially sustainable, social enterprise that achieves its growth and targets whilst operating within values based on community development and cohesion.

The Science Behind Lumosity: Color Match
How flexible is your brain? Give it a 5 second test: quickly identify the color of each of the above words (don't read them). Say the colors out loud.
How accurate were you? How long did it take? This task, called the Stroop Test, is more challenging than it first appears. It’s much harder to identify a color when it’s different from the word than it is to identify when the two match. This challenging test highlights the importance of selective attention—a skill that you can improve.

Brief history of the Stroop Test
In 1935, John Ridley Stroop became the first to publish in English on the current version of this cognitive task. Developed as part of his dissertation at George Peabody College, his task became the basis for the Stroop Test, which remains a widely used neuropsychological assessment to this day.
How your brain processes the Stroop Test
The Stroop Test challenges selective attention, or your ability to carefully choose which stimuli to focus on—and which to ignore. The mental flexibility required to switch between multiple stimuli is essential: without good selective attention, it’s easy to make errors (such as reading a word instead of saying its color).
