I am troubled by the conclusion drawn in this article. The report says that college-educated adults do better on memory tests, displaying pronounced frontal brain activity, than do their less-educated peers. Might it not be just as reasonable to hypothesize that those who are able to “recruit the frontal brain into a memory system” do better in school and are, therefore, more likely to extend their educations?
