Repressors—people who unconsciously inhibit their display of emotion—exhibit significant increases in heart rate when they encounter emotion-provoking situations. Nonrepressors have similar physiological responses when they encounter such situations and consciously inhibit their display of emotion. Thus the very act of inhibiting unconsciously, causes a sharp rise in heart rate.
