2. Brain Development
• It begins shortly after conception and
continuous through the life span
• Maybe affected through sensing pathways by
sound, touch, vision, smell, and thoughts.
• The important aspects of brain is the ability to
change during young age.

3. The Brain

5. Brain

7. The Human Brain
• Frontal lobe –
voluntary
movement,thinking,
and personality
• Parietal lobe - speech,
language, attention,
sensation, motor
control
• Occipital Lobe- Vision
• Temporal Lobe -
hearing, language and
memory processing

8. Early Childhood
Rapid change of brain
Process of myelination continue and brain size
increase
Brain Plasticity
Flexible and prepared to learn
Blooming and Pruning

9. Early Childhood
3 years – Most rapid changes due to
bombardment of experiences
- Brain is ¾ of adult size
- 1090 grams for famale brain
- 1270 grams for male brain

10. Early Childhood
4 years old – brain increase 80% of adult size
- Temporal Lobe (auditory
myelination is complete)
5 years Old - Occipital lobe reaches adult
levels

11. Early Childhood
Effects of Neglect and/ or abuse
- the frontal lobe develops improperly when
deprived of affection and positive emotional
experiences
- Lack of stimulation causes
neurons in the brain to die off

12. Effects of Neglect and/ or abuse

14. Middle Childhood
• Brain volume stabilizes
Weight : 1440 grams in male
1260 grams in female
6- 7 years old –maturation of occipital lobe
- Contrast sensitivity and peripheral
vision reach adult levels
8 years old- maturation of temporal lobe
Brain maintain flexible for future learning

15. Adolescence
• Transition from childhood to adulthood
• Social, psychological and emotional changes
accompany by puberty
• Selective pruning takes place
- Frontal lobe loses 3%
• Myelination- allows to operate more effeciency
• Emotional Control
Amygdala- Holds emotional memory
- develops before frontal develops

16. Adolescence
• Teens experience a greater desire and need to
thrill-seeking than any other age group

21. Genetics and Environment
• There is an evident that early experience can
dramatically alter the genes are expressed in
developing brain
• Teens experience is a greater desire & need to
thrill-seeking than any other age group
