Jonah and Eli are having a conversation about how the brain works. Jonah maintains that the brain must be much more active when a person is focused and attending to a problem, while Eli points out that the brain operates with the same activity no matter how focused a person is. Who is right?
a. ?Neither is right, because the brain exhibits about 5% more activity when a person is focused compared to when they are unfocused.
b. ?Jonah is right, as the brain shows between an 80 and 85% increase in activity when a person is focused compared to when they are unfocused.
c. ?Eli is right, because the brain activity level does not change at all when a person’s focus level changes.
d. ?Neither is right, because the brain actually exhibits 10 to 15% lessactivity when a person is focused compared to when they are unfocused.
