Marjoe has been under a lot of stress lately. His doctor recommended a biofeedback specialist who uses equipment to measure Marjoe’s blood pressure, heart rate, and muscle tension. Marjoe asked the specialist how the machines worked. How would the

specialist answer Marjoe’s question?

A) “This equipment electronically stimulates your heart, muscles, and other organs; by energizing them to become more active, your body will get used to your elevated levels of stress.”
B) “This equipment applies a brief electric shock to your organs whenever their activity passes above a certain threshold; that punishment will eventually train you to lower your physiological activity.”
C) “This equipment can measure when your muscles tense or your blood pressure elevates; this information can prompt you to practice steps to relax.”
D) “This equipment simply measures your current levels of physiological responding; after we unhook you from the machines, I’ll teach you some exercises that form the basis of biofeedback.”

C) “This equipment can measure when your muscles tense or your blood pressure elevates; this information can prompt you to practice steps to relax.”
