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). 


 

 Quando se desenvolve um trabalho de Natação para Adultos por um tempo relativamente longo, um aspecto que nos chama a atenção é a ampla gama de motivos pelos quais uma pessoa de 30, 40, 50 e até bem mais anos resolve aprender a nadar, numa fase de vida em que muitos estão procurando “desacelerar”.

Não que eu tenha feito uma pesquisa formal sobre esse tema. Infelizmente não tive essa oportunidade, pois estou convencido de que ela resultaria em um belo trabalho. Mas de qualquer forma, acho que vale a pena alguns comentários à esse respeito, já que muito de nossas atitudes em aula devem estar consonantes com os motivos que levaram nossos alunos a procurar nossos serviços.

416nTPsDcOL. SL300 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.

Combining memoir with a clear explanation of what makes cancer cells thrive and what inhibits them, and describing both conventional and alternative ways to slow and prevent cancer, Anticancer is revolutionary in its clarity. It is a moving story of a doctor's inner and outer search for healing; radical in its discussion of the environment, lifestyle, and trauma; and inspiring and cautionary in its certainty that cancer cells lie dormant in all of us - and we all must care for the "terrain" in which they exist.

Mineral Ipes Brancos 28 set 2012Em uma conferência, ao explicar para a platéia a forma de controlar o estresse, o palestrante levantou um copo com água e perguntou:

-"Qual o peso deste copo d'água? " As respostas variaram de 250g a 700g.

O palestrante, então, disse:- "O peso real não importa. Isso depende de por quanto tempo você segurar o copo levantado. Se o copo for mantido levantado durante um minuto, isso não é um problema. Se eu o mantenho levantado por uma hora, vou acabar com dor no braço. Mas se eu ficar segurando um dia inteiro, provavelmente eu vou ter cãibras dolorosas e vocês terão de chamar uma ambulância."
