Study Notes
Overview
- Adolescence is the transition from childhood to adulthood, marked by physical, mental, and emotional development into a responsible adult.
- Key tasks include building relationships, forming an identity, developing future goals, enhancing independence and self-confidence, and building social skills.
Risk-Taking Behaviors
- Adolescents commonly engage in risk-taking for excitement, evident in statistics linking risky behavior to health risks.
- 62% of deaths in Germany among 15-20 year olds are due to traumatic injuries like traffic accidents, violence, and self-harm.
- These fatalities are often linked to drunk driving, not wearing seatbelts, carrying weapons, substance abuse, and unprotected sex.
Gender Differences in Risk-Taking
- Risky behaviors are common among boys and girls, with roughly equal smoking rates recently.
- Qualitative differences persist, with boys smoking more cigarettes and "harder" tobacco.
- Boys prefer beer and liquor, consume more alcohol, use illegal drugs more, and are more accident-prone while girls are more likely to have unhealthy eating habits.
Methodology
- A review of neurobiological insights into adolescent behavior was performed.
- Relevant publications were located via searches in German library catalogs and the PubMed database.
