Early Childhood Development Flashcards
Sequence of brain development is (blank)
genetically programmed
(blank) of brain development is shaped by experience.
quality
What is the link between experience and innate ability?
neuroplasticity
To learn a fact or skill there must be persistent (blank) in the brain that represent the new knowledge
changes
Every skill you have, every fact you know, every memory you hold hs a (blank) in the brain
physical form
The brain is shaped by (blank)
experience
In a newborn brain, brain activity is confied to (blank)
subcortical structures (brainste,, cerebellum, thalamus)
What is the most undeveloped part of the newborn brain?
cerebral cortex
How does the brain develop?
from bottom up
What are the newborn reflexes?
Moro, root, suck, grasp, tonic neck, babinski
When do the newborn reflexes get suppressed as upper motor neurons?
when the cortex matures
What are the nwborn senses?
touch vestibular smell taste hearing vision (primitive)
At what age do you get synapse formation?
36 weeks gestation to 2 years
At what age do you get synapse pruning?
4 years to 6 years
What is the critical period?
the window of time in which brain has heightened ability to rewire in response to input from environment
Inadequate sitmulate during critical period can have permanent (blank)
disabling effect
How can you get congenital cataracts? What can result if not detected by 6 months?
lack of sitmulation to visual cortex
permanent vision impairment
What happens if you have language deprivation as a baby?
you will never be able to use grammer or assemble sentences correctly if
What happens if you have socia/global deprivation?
severe development and psychiatic problems due to lack of attention, love and physical contact early in life. Usually deeply trouble for life, even if adopted by loving family
Achievement of developmental milestones is a result of (blank) and (Blank) in cortical areas controlling those functions
synapse formation and pruning
If appropriate stimulation is absent/insufficient before the process of synapse formation and pruning is complete, then what happens?
an ability may be permanently lost
This is why recognition of developmental delay and early intervention are so important
What are the four major developmental domains?
gross motor
fine motor
language
social-emotional
New skills develop with maturations of (blank) and (blank)
motor cortex
complex feedback circuits
(medial and lateral premotor cortex, primary motor cortex, primary somatic sensory cortex)
What do the complex feedback circuits involve?
sensation and proprioception
How old is a child if they can lift head and shoulders when prone, has good head contol and begins to roll?
4 months
How old is a child if they are able to lift head when prone?
2 months
How old is a child if they can sit well alone?
8 months
HOw old is a child if they can roll well and sit in a tripod?
6 months
HOw old is child if they can crawl and pull to a stand?
9-10 months
How old is a child if they can walk without support?
12-15 months
How old is a child if thye can throw a ball overhand, runs , stoop to pick up a toy?
18 months
How old is a child if they can kick balls, climbs into chairs and jump?
24 months
What are gross motor red flags!?!?!?!?!
No head control by 4 months Does not sit alone by 8 months Does not crawl by 10 months Does not walk by 15 months Toe walks at least 50% of time after 6 months of walking alone
