As a result of higher cortical arousal levels, introverts: group of answer choices have higher pain thresholds than extraverts. react less strongly than extraverts to sensory stimulation. need, and actively seek, excitement and stimulation. exhibit greater sensitivity to low-level stimuli than extraverts.

Exhibit greater sensitivity to low-level stimuli than extroverts

Explanation:

It is proven through research that introverts have higher sensitivity to low-level stimuli than extroverts. This is because introverts have higher cortical arousal levels. On the other hand, the extroverts are found to have lower cortical arousal levels and this results in need for external excitement and stimulation. Also, introverts have lower pain thresholds than extroverts and react strongly to sensory stimulation. Hence, the only correct option provided here is that introverts exhibit greater sensitivity to low-level stimuli than extroverts.
