If you’re a parent of a teenager and you’ve ever wondered why your kid behaves so recklessly, the winner of the Intel International Science Fair, and former Harvard student, Kashfia Rahman, may have the answer to your question. During her junior year of highschool she initiated a research on this very topic and the results were actually not what you may think. The premise behind her research was why individuals between the ages of 13 and 18 are more prone to risk-taking than adults and children, and if the continued exposure to risky activities could actually modify how riskiness is perceived by the brain. This process is called habituation, literally “getting used to”. She started by buying a portable EEG headset in order to record her peers, who had to wear said headset while sitting down in one of the many cubicles that their high school's library had to offer, doing a computerized decision making simulation. This was done to measure their risk taking behavior in comparison to the ones in the real world. The testing was done 12 times over a 3 day period, to ensure fair exposure to the activities. The subjects selected for the experiments were 86 students all of various ages, but always between the ages of 13 and 18. A control panel in the EEG also recorded and measured their variation in emotional responses as they took the test; responses such as: attention, interest, excitement, frustration, guilt, stress level and relaxation. The data actually confirmed the initial claim: habituation can in fact alter the brain’s perception of risk, causing reactions opposite of what would be considered “normal”, and even making the brain itself crave these feelings. We then can’t blame the teen who unconsciously searches for the “thrill” or the “rush”, because the origin of recklessness can be found in a combination of the “immaturity” of the developing brain and the environment the individual is exposed to. It can be speculated that an individual who is not familiar with this type of behavior won’t exert it as much as an individual who, for example, grew up around said environment would.
