Question

The question states that hippocampus volume in one area is associated with higher levels of neuroticism, and previous studies found the same association with stress and depression. Thus, it is likely that the volume in this area is reduced in individuals with higher levels of neuroticism. Additionally, the question states that the mid-cingulate cortex is believed to be associated with pain sensitivity, and was smaller in individuals with higher levels of neuroticism. Therefore, the best choice is B, reduced volume in the hippocampus and mid-cingulate cortex for individuals with higher levels of neuroticism.
