Angela Stewart · Accepted Answer

Final Answer : C, Explanation :  Eysenck proposed that introverts have a higher baseline level of cortical arousal than extraverts due to differences in their reticular activation system (RAS), which controls arousal and attention. Specifically, introverts have a higher level of sensitivity to external stimuli due to a more easily aroused RAS, which causes them to feel overwhelmed by excessive stimulation and seek out low-stimulus environments to reduce the arousal level. In contrast, extraverts have a relatively lower baseline level of arousal in their RAS, which causes them to seek out high-stimulus environments to increase their arousal level above the optimal threshold.

Eysenck suggested that the _____ of extraverts and introverts differs with respect to the baseline level of arousal.

A) somatosensory cortex
B) thalamus
C) reticular activation system
D) occipital lobe
