When IQ is 100=100 is average
○
Average range from 85-115 (65%)
○
Average IQ for all of us is 100
•
High IQ of 170
○
Difficult to measure= usually nonverbal
▪
Low IQ of 30
○
Use the scale to identify kids who are gifted and disabled
•
Most common
○
IEP are used
○
Formal intelligence test- formal psychologist must administer it
○
Test include measuring inherit abilities of processing information
○
Weschler’s Intelligence Scale for Children (WISC – III)
•
Weschler’s Adult Intelligence Scale (WAIS -III)
•
Measures of Intelligence
Born with a capacity
○
All born with a stable intelligence that comes with you for your life
▪
It is the same for an individual in all ages
○
CAPACITY: you can push it but there is a limit and that limit is the upper end of your IQ
○
Historically thought to be a stable trait
•
What is Intelligence
Price et al (2011) in Nature
•
33 teens followed from 12-16
•
Huge changes in IQ –as much as 20pts (not stable)
•
Lots of things are happening biologically and environmentally
○
Adolescence fluctuate IQ
•
What we know now…
Large area with confusing streets
•
Measure IQ and neurologically
•
Right= visual/spatial
○
Found that the right hemisphere was well develop
•
Scored highly compared to controls: by having that long experience have increased the IQ
•
Push us to think differently

Week 8: Intelligence
CHYS 2P35 Page 1
Northstone, University in Bristol, England
•
4000 three and four-year olds
•
Diet lower in fat, sugar, and processed food correlated with an IQ score up to 5 pts higher
•
Diet
717 children living in urban and suburban neighborhoods
○
Neighborhood
□
Densely populated
▪
Urban –significant decline in IQ between 6-11
○
Suburban –no change
○
Not due to mom’s IQ, education, or marital status
○
Due to neighborhood
○

•
Environmental Influence
General capacity that we may have that can be loosely measured with IQ tests
•
So what’s with the notion of stability?
Young kids are open to shaping neural networks
•
We can change the neurological pathways the most in young children through environment
•
Less easy the older we get
•
More free neurons available
▪
Us it or lose it principle hasn’t kicked in
○
"can't teach an old dog new tricks"
•
ITS COMPLEX AND COMPLICATED
•
Neural Plasticity
Cognitive practices help push our IQ
•
Processing information
•
“How” we process information
•
This can be learned
•
Implications for education
•
Cognition
Fluent
•
Malleable- has to be tough early
•
Upper limits?
•
How to think about intelligence
I don’t think kid #2 doesn’t know the difference between cars and trucks
□
Said his first words at 3 years old
▪
Felt like he didn’t need to talk
▪
Late in talking, but everything else was fine
○
Allow us to understand what this capacity is
▪
EXTREME- 170 1Q
○
Had another kid- developed typically
○
Trajectory example
•
Students have particular needs
•
The norm
▪
Understand typical development in order to understand typical development
○
Students with extraordinary abilities and skills
•
Well in advance of developmental norms
•
Sometimes specific
•
Sometimes general
•
Reflected in high ability or IQ scores
•
Giftedness
High to genius range 130+
•
Kids who are gifted had different instructions, instructors and trips
•
Job as educators to push that capacity
•
