DeYoung and Colleagues (2010) Were Able to Identify Brain Regions

Multiple Choice

DeYoung and colleagues (2010) were able to identify brain regions correlated with variations in Big Five traits. Your textbook authors note that one reason one must exercise caution when interpreting these results is that "the brains' various regions are enormously interconnected." What did they mean by this?

A) The connectivity makes it difficult to figure out whether variations in brain volume caused variations in traits or vice-versa.
B) The connectivity suggests that studying the brain, even with an MRI, will always lead one to draw false conclusions about traits.
C) The connectivity makes focusing on more than one brain area problematic because only one brain area is ever active during a given complex task.
D) The connectivity makes focusing on one brain area problematic because several brain areas are active during a given complex task.
