Moral Decision-Making & Sleep + Adolescent Brain & Risk-Taking (The Mind Explained / General Context)

• How do new cognitive capabilities influence moral decision-making?

• Formal operational thought allows teens to think abstractly about ideals, values, and hypothetical scenarios, helping them build an internal moral compass rather than just following external rules.

• Why is sleep important for adolescent development, and what factors affect it?

• Importance: Teens need 8 to 10 hours of sleep for physical and cognitive recovery; lack of sleep is linked to mental health issues and poor performance.

• Influencing Factors: A 2-hour biological circadian rhythm shift (falling asleep later), early school start times, heavy homework/after-school obligations, and screen time.

• What teen behaviors seem to be "universal"?

• Seeking novel experiences, taking risks, and prioritizing peer relationships.

• What proposed reasons explain why teens engage in risky behavior and seek novel experiences?

• Maturation of the brain's reward-seeking emotional centers occurs faster than the development of the prefrontal cortex, which handles impulse control and long-term planning.

• What is the "speed limit" metaphor, and how does it apply to adolescents?

• It compares the brain to a car where the accelerator (emotional/reward system) is fully developed, but the brakes (prefrontal cortex/self-control) are still under construction, leading to risky driving without enough braking power.
