Answer to Question 1
ANS: C
The cognitive-evaluative system overlies the individual's learned behavior concerning the expe-rience of pain and can modulate perception of pain. The sensory-discriminative system is medi-ated by the somatosensory cortex and is responsible for identifying the presence, character, loca-tion, and intensity of pain. The affective-motivational system determines an individual's condi-tioned avoidance behaviors and emotional responses to pain. The reticular-activating system does not play a role in the perception of pain.
