How risk-taking changes a teenager's brain | Kashfia Rahman
Understanding Teen Risk-Taking Behavior
The Paradox of Teenagers
- Have you ever tried to understand a teenager? It's exhausting, right? Some teens excel academically and engage in community service, yet they also partake in dangerous behaviors like eating Tide Pods and binge drinking.
Curiosity About Risk-Taking
- At 16, the speaker observed peers engaging in risky behavior despite prior education on safety (e.g., DARE class). This contradiction sparked curiosity about why teens take such risks.
Scientific Exploration of the Teenage Brain
- Neuroscientists have found that the teenage brain is still maturing, which contributes to poor decision-making and increased risk-taking. The question arises: Why are teens more vulnerable than children?
Habituation as a Psychological Process
- The speaker's research was based on "habituation," where repeated exposure to behaviors can dull emotional responses. This concept led to investigating if it applies to teen risk-taking behaviors.
Research Challenges and Innovations
- Conducting research posed challenges due to limited resources at the speaker's high school in South Dakota. Despite these obstacles, creativity allowed for innovative methodologies, including transforming a library into a lab.
Methodology of the Study
- The study involved 86 students aged 13 to 18 completing a computerized decision-making simulation while wearing EEG headsets to measure emotional responses over multiple exposures. This aimed to assess habituation effects on risk-taking behavior.

The Impact of Brain Development on Risk-Taking
- Teenagers often lose their natural fear and caution instincts due to brain development, leading to increased thrill-seeking behaviors.
- Consequences include a lack of self-control in decision-making, greater risk-taking, and harmful choices; this is influenced by both brain development and habituation to risks.
- Habituation can physically alter a teen's brain, exacerbating risk-taking behavior. This combination creates a "perfect storm" for dangerous actions among teens.
Insights for Parents and Teens
- Research findings emphasize that teens are not merely defying authority; they struggle with habituation to risks which dulls their protective instincts against danger.
- There is a call for policies that create safer environments while also educating about the psychological impacts of repeated risky behaviors.
Personal Journey and Recognition
- The speaker presented research at the Intel International Science and Engineering Fair (ISEF), gaining valuable feedback from experts in neuroscience and psychology.
