The document discusses adolescent brain development and provides strategies for parenting teenagers. It explains that the teenage brain is still developing key regions related to decision-making and emotional regulation. Specifically, the prefrontal cortex develops last and the amygdala is more active due to hormones, making teenagers more susceptible to emotional decisions and peer pressure. The document recommends exercising, sleeping, eating healthy, and reducing stress to support brain development. It also suggests openly communicating values and decisions with teenagers, giving them autonomy appropriately, and helping them learn to reason through situations.

4. Adolescence
“Teenagers [are like] people
constantly on LSD. People on
acid are intense, changeable,
internal, often cryptic and
uncommunicative, and, of course,
dealing with a different reality.”
Mary Pipher, Reviving Ophelia

6. Developmental Characteristics of
Adolescence
• Identity Formation
• Tenuous Sense of Self
• Self-Regulation
• Imaginary Audience
• Development of Self-Esteem
• Adolescent Egocentricism
• Importance of Peer Relationships
• Formation of Groups, Crowds and Cliques

children’s adolescence
manifest itself in their
interactions and behavior?
How do you support them?

10. Stuff We Kinda Knew Already…
With a Twist
• Exercise
• Sleep
• Nutrition
• Stress

11. Exercise
• 30 minutes of aerobic activity
• 2-3 times a week

12. Sleep
• Effects of sleep much more pronounced
in children and adolescents
• Chronotypes (morning/night
people)
• The Nap Zone
• Dangers of Sleep
Deprivation

15. Adolescent Brain Research
• Brain keeps growing and developing to age 25!
• Teen brain is a “late childhood brain”
– Capacity to learn things quickly
– Connections between different sections of the
brain aren’t fully developed yet.
– Brain is pruning and re-wiring neurons during
this time
– Amygdala is getting hyper triggered by
hormones
– Prefrontal Cortex (frontal lobe) is last place for
connections to develop.

16. The Two Brains
• Rational Brain and
Emotional Brain
• Both Valuable,
Both Able to
Mislead
• Emotional

Origin

17. The Emotional Brain
• Pattern Recognition
Without Conscious
Awareness
• Motivates Behavior
Change Through
Feelings, Autonomic
Responses
• First Impression
• Thin Slice of
Information

18. Pre-Frontal Cortex: PFC
• High level reasoning
• Decision-making
• Impulse control
• Assessment of consequences
• Planning, strategizing, organizing
• Inhibiting inappropriate behavior
• Adjusting behavior when the
situation changes
• Setting priorities
• Estimating and understanding
probabilities

19. The Problem
• Cognitive abilities 
performance
• Analysis  primary
mode of decision-
making
• Competence  use
of that competence

20. PFC vs Amygdala
PFC:
Situation 
Assess 
Plan
Amygdala:
Situation 
Emotion/Feeling 
React

21. Peer Pressure
• Computerized risk-taking
tests done alone and while
watched by friends:
– Adults: peers have no effect
– Adolescents: peers doubles
the number of risks taken
• Brain scans at the same
time suggest presence of
friends activates a different
part of the brain

22. Implications
• They ARE capable
• Circumstances matter
• Social + Emotional +
Intellectual = Decision
• Amygdala first, PFC
last
• Gut response first,
reason second

new, interesting,

you seeing some
adolescent behaviors
in your children in a
new light?

24. Supporting Our Kids
Rosetta Eun Ryong Lee (http://tiny.cc/rosettalee)

25. Living Out Loud
• Talk about your day and
show interest in theirs
• Talk positively and
realistically about yourself
• Make mistakes out loud
• Tell your stories
• Emote out loud
• Reason out loud
• Make your values clear
• Walk your talk
• Listen, listen, listen

26. Respecting Them
• Involve them in decision-making
• Explain the “why”
• Recognize their developing
capacity
• Recognize that, even at 17, their
decision-making may be different
than “mature” decision-making
• Recognize situations that
influence rational decision-making
• Limits are necessary
• Some autonomy is necessary
• Help them reason through
decisions
