ADOLESCENT BRAIN DEVELOPMENT & IMPLICATIONS ON EMOTION & PERSONALITY
Boys' brain are bigger than girls' ?
BUT... weak correlation between size and intelligence
Max size does not imply max maturity...
Adolescent Emotion & Personalities
mood swing
I-Know-What-I-Am-Doing
Rebellious
Adolescent Attitudes & Behaviour
Fearless!
New experiences
Seeking social attention
Each connections form a 'synapse'
Neural connections are arranged through 3 main processes
Proliferation
rapid development in the brain where neural connections are formed
Pruning
connections that less / not used will be pruned away
Myelination
neural pathways (axons) are sheathed with myelin to allow efficient transmission of signals
ADOLESCENT BRAIN
Depends largely on amygdala
Fight or flight
Wrongly intepret emotions
Sensitive to social situations
Easily stressed (mental health issues)
ADULT BRAIN
Depends more on Prefrontal Cortex (PFC)
Controls impulsiveness
Make rational decisions
Emotion control
Self-control
PROLIFERATION : Grey Matters
Rapid of development of Grey Matter in children (neural connection)
-Reduces during adolescence
Connection between different parts of brain
PRUNING : Reduction of Grey Matters
Unnecessary connections are eliminated or pruned away
USE IT
or
LOSE IT!
( like muscles )
Adapt based on experience and environment
Learning takes place most during this time
MYELINATION : Development of White Matter
White matter is myelinated axons
Allows communication between the neurons
White matter develops continuously from birth, peaks during puberty
ADOLESCENTS & ADDICTION
Smoking, drugs, pronography stimulate the reward centre
Neural connection from reward centre to memory centre (hippocampus) becomes stronger over time
IMPLICATIONS ON EMOTION & PERSONALITY
fail to consider consequences (eg covid party, russian roulette, drink driving)
gut feeling behaviours, high-risk
Sensation seeking
rebellious
highly motivated for social relations
easily influenced by friends
addiction, substance abuse
easily stressed
