Eysenck Predicted That Individuals High on Extraversion Would Experience Lower

Eysenck predicted that individuals high on extraversion would experience lower cortical arousal in response to environmental stimuli. What pattern of results did Kehoe et al. find when looking at the fMRI activity of those high in extraversion?

A) Activity in the cerebellum was lower than those low in extraversion, whereas activity in the insula was higher than those low in extraversion.
B) Activity in the cerebellum and in the insula was higher than those low in extraversion.
C) Activity in the cerebellum was lower than those low in extraversion, whereas activity in the insula was lower than those low in extraversion.
D) There were no differences in activity of the cerebellum and insula among those high and low in extraversion.
