According to Eysenck, who would have the LEAST reactive reticular activating system?
A) Grace, who likes to read
B) Tucker, who likes to fish
C) Lily, who likes to talk
D) Ben, who likes to surf
Answer: D
Rationale: Hans Eysenck proposed that arousal states of the brain are the basis of extraversion and that the reactivity of the limbic system (the emotional circuits), reticular activating system, and cortex are correlated with extraversion. People who have decreased reactivity in these brain regions are basically "underaroused." As a consequence, they seek out novel social and emotional stimulation. Introverts, by comparison, have higher reactivity within these brain regions and, therefore, seek less stimulation than do extraverts.
