Hedden and his colleagues (2008) examined the brain activity of East Asians and European Americans while they underwent an fMRI

They found that Americans had more brain activity when they were told to pay attention to the box around the line than when they paid attention to the line. Why was there greater brain activity in this condition? a. Participants' brains had to work harder to perceive objects in a way that was not their typical way. b. Participants' brains did not have to work very hard to perceive the objects, so they could think about other things, thereby increasing their brain activity. c.
