TEXTO PARA AS QUESTÕES DE 40 A 42
You know the exit is somewhere along this stretch of highway, but
you have never taken it before and do not want to miss it. As you
carefully scan the side of the road for the exit sign, numerous
distractions intrude on your visual field: billboards, a snazzy convertible,
a cell phone buzzing on the dashboard. How does your brain focus on the
task at hand?
To answer this question, neuroscientists generally study the way
the brain strengthens its response to what you are looking for – jolting
itself with an especially large electrical pulse when you see it. Another
mental trick may be just as important, according to a study published in April
in the Journal of Neuroscience: the brain deliberately weakens its
reaction to everything else so that the target seems more important in
comparison.
Such research may eventually help scientists understand what is happening in the brains of people with
attention problems, such as attention�deficit/hyperactivity disorder. And in a world increasingly permeated by
distractions – a major contributor to traffic accidents – any insights into how the brain pays attention should get ours.

Segundo estudo publicado no Journal of Neuroscience, mencionado no texto,
A)
nossa buca pela realização de tarefas diversas aumenta o número de pulsações elétricas produzidas pelo
cérebro.
B) os neurocientistas estão estudando como, sem grande esforço, conseguimos focalizar uma coisa de cada vez.
C) as pulsações elétricas produzidas pelo cérebro são intensas e constantes.
D) nosso cérebro reduz sua reação a estímulos que são menos relevantes para a tarefa a ser realizada,
mantendo o foco.
E) o tipo de resposta que nosso cérebro fornece frente a novas tarefas ainda é uma questão a ser
respondida pelos pesquisadores.

O Texto afirma em “Another mental trick may Be just as important, according to a study published in April in the
Journal of Neuroscience: the brain deliberately weakens its reaction to everything else so that the target seems more
important in comparison” que nosso cérebro enfraquece sua reação à qualquer coisa diferente do nosso foco, a fim
de que, a atividade em questão, se torne mais importante em comparação a tudo que poderia nos roubar a atenção.
