People classified as “novelty-seekers” or “high-sensation seekers,” are more likely to use drugs and gamble than their personality opposites, “low-sensation seekers.”1 Novelty-seekers have physiologically different brains than cautious people, says Dr. Carl Schwartz of Harvard. Thrill-seeking, such as bungee jumping, may be a way to activate the reward system to overcome a lower base-line of natural stimulation from a sluggish Limbic “reward” system, he says.2
Thrill-seekers also have correspondingly higher electrical responses in their brains as visual or acoustic stimuli increase, whereas low-sensation seekers show less brain activity as the intensity of the stimulus increases. This too may be because high-sensation seekers have a lower base line of brain arousal and need persistent stimulation to compensate.3
