TED-Ed: When are you actually an adult? | Shannon Odell

The video explores the concept of adulthood, questioning if age is the best measure of maturity. It discusses the arbitrary nature of age limits, like voting age, and examines brain and cognitive development as indicators of maturity. Brain development involves changes in gray and white matter, while cognitive abilities like reasoning and problem-solving mature at different times. The video highlights that maturity is not tied to a specific age but occurs in waves, influenced by genetics, environment, and experiences. It suggests that judicial systems should consider the ongoing development of the emerging adult brain.

Why is the voting age considered arbitrary by some people?

• Because it is determined by cultural traditions.

• Because it is based on scientific research.

• Because it does not accurately reflect maturity.

• Because it is the same in every country.

What is the role of gray matter in brain development?

• It facilitates long-range communication.

• It helps in short-range communication and information processing.

• It is responsible for emotional regulation.

• It is involved in muscle coordination.

How does white matter contribute to brain function?

• By reducing energy efficiency.

• By insulating connections for fast communication.

• By pruning unused connections.

• By increasing emotional responses.

At what age do teens perform similarly to adults in reasoning tasks?

• 25

• 16

• 21

• 18

What influences the behavior of 18 to 21-year-olds in social situations?

• Their ability to drive.

• Their brain's focus on social and emotional elements.

• Their physical strength.

• Their knowledge of politics.

Why do some scientists suggest expanding juvenile courts to include late teens and early 20s?

• Because they have more life experience.

• Because they are financially dependent.

• Because their brains are still developing.

• Because they are physically weaker.

What does neuroscience suggest about the journey to adulthood?

• It is the same for everyone.

• It is determined solely by genetics.

• It involves waves of maturity influenced by various factors.

• It is completed by the age of 18.
