Question

Quizplus · Accepted Answer

Recent research in personality neuroscience has found a relationship between certain personality traits and the volume of various brain structures. For example, people with higher levels of extraversion tend to have larger volumes in the medial orbitofrontal cortex, whereas those with higher levels of neuroticism tend to have smaller volumes in the anterior cingulate cortex.

Answer: C 
 There is some evidence that certain personality traits, such as openness to experience, may be associated with greater connectivity between the left and right cerebral hemispheres. This suggests that there may be neural mechanisms underlying some aspects of personality that involve the integration of information processing across different brain regions.

Answer: D 
 While there is some evidence that certain neurotransmitter systems may be related to personality traits, the ratio of agonist to antagonist neurotransmitters in an individual's neural system is unlikely to be a useful predictor of personality. The relationship between neurotransmitter activity and personality is likely to be far more complex and multifaceted than can be captured by a simple ratio.
