Primacy
Experience-Expectant Growth
oRequires certain environmental triggers
Our environment must support and provide animations
Necessary for healthy functioning
oExample: sensory: see, hear, touch, talk, smell, taste
oCritical periods
A developmental window of opportunity to stimulate
Example- children who are born with cataracts
If removed before 6 months, infant will see same as one who
didn’t have an eye problem
If removed after 6 months, the infant will never be able to see
clearly
Importance of Early Intervention
oAbecedarian Program
Study of impoverishment and IQ 1970
Based around financial stress
Comprehensive strategies- provided nutritional supplements
3 groups
oGroup 1- Birth- Kindergarten
Enriched environment
Enrolled in a very well designed and intensive day
care
oGroup 2- Kindergarten-2nd grade
Focused on the school system
Provided each child with a master teacher
oGroup 3- Birth- 2nd grade
A combination of the first two groups
Intensive daycare AND master teacher
Groups that started at birth showed improvements in IQ scores
oAutism
Diagnose as early as possible
By 18 months is key, rather than 5 years
The earlier you begin, the more window of improvement
Brain Development during infancy
oThere is great potential
oSynaptic Pruning
Rare potential to over prune
oBrain Plasticity
The ability to recover
Take lost area and reassign to other matter
Most plastic when we are very young
oMyelination

By 18 months is key, rather than 5 years. The earlier you begin, the more window of improvement. Brain development during infancy: there is great potential, synaptic pruning. Rare potential to over prune: brain plasticity. Take lost area and reassign to other matter.
