Intelligence Lecture 1
Problem Solving !
Psychometric Approach !
Bias !
Next time: More Intelligence P 348-362 !
!
How do we solve problems?!
What is intelligence !
How do you measure intelligence?!
!
!
OH 1:30 -3 !
!
!
Smoking volcanoes can be bad for your health- according to chomsky this sentence has !
2 deep 1 surface structure !
Chomsky analysis of grammer****!
Problem Solving !
Monk problem !
love using graphical analysis !
Lily problem !
day 59 !
10 volume book set !
802 due to arrangement of the books !
nine dot problem!
Sternberg & davidson !
correct solutions to insight problems involve:!
selective encoding !
sebentice combination!
selective comparison !
Intelligence !
What is intelligence?!
a host of abilities (memory, creativity, fast react time etc. )!
what a test measures !
but tests can be misleading !
lots o studies suggest that unschooled people in remote villages cannot save
syllogisms
also suggests that preliterate people do not (can not) use logical analysis !
Scribbler!
All knell men are rice farmers, Mr Smith is not a rice farmer. Is he a Kpelle man? !
they said they don't guess questions that they don't know !
Look at ecological approach !
we need to see that if we design a test it may work in one location but not
another !
need to look at validity !
Psychometric Approach !
Galton - wants to find the intelligence of ppl!
looks at relative of intelligence of people !
relative of intelligent people are also intelligent !

Only pages 1-2 are available for preview. Some parts have been intentionally blurred.

starts research program to identify those with low ability !
want to help school system out by weeding out low intelligent people !
measure simple motor and sensory abilities !
believes that intelligence is about being unitary ( mentally quick (reaction time)) !
developed the correlation coecient !
but results are disappointing - for him bc he believed that intellect was genetic and a
single thing !
no strong evidence for this !
Binet !
operating on a request from the french government (public school was mandatory in
france)!
wanted to find intelligence of all student to know who and struggling and help them
Galton !
believed that intelligence was a collection of higher order abilities !
No correlation Galton !
can be good at one thing and be poor at other and still be intelligent !
ability that you have results from learning not genetics (acquired ability) Glaton !
Binet and Simon !
developed test tapping a number a abilities (memory math etc. )!
made teachers rate the students!
correlated the scores of the students to the teachers rating (method: Criterion Validity) !
Tests were revised and concept of mental age is introduced !
They standardized the test!
and can get age norms (mean performance of age groups) !
assign a new test score to mental age group according to norms !
so if a person performs at level of avg 5 year olds they are assigned a mental age of 5 !
Mental age - gives us what intelligence is about !
Terman!
created the concept go IQ!
adapted Binet scale for use in the US at stanford !
Standard Binet is a widely used test to measure intelligence !
gives you an IQ score!
IQ = (Mental age/ Chronological age ) X 100
if child is is 10 years old but scores at level of avg 12 years old !
(12/10) X 100 !
120 !
if same chile score at 8 yeas old level !
(8/10)X 100!
80!
Stanford binet is designed for children not appropriate for adults ! !
Wechsler Adult Intelligence Scale (currently in version 4) !
WAIS - IV!
WISC - IV!
Wechsler intelligence scale for children !
WAIS -4 has 10 sub scales with verbal and performance measure !
reading, math etc.!
IQ score based on mental age breaks down with adults (once over age of 12) !
bc if 20 year ld score at 60 year yr old then iq = 300 ! !
SO we have to use deviation IQ !
z-score !

Standardizing amongst people who took the test !
Standard disrtubution!
68%!
14% 14%!
95% bw +2 and -2 !
On a WAIS scale mean = 100 and Stand
deviation = 15!
if you fall 1 above then !Q= 115 !
Concerns of the tests: !
Reliability : consistency of measurement !
score the same if test taken repeatedly!
TEST - RETEST!
r= 0.80 to 0.95 for stand ford binet and WAIS IV!
Validity: does the test measure what it is suppose to be measuring? !
measuring intelligence really? !
correlation(r) with achievement !
range: 0.3 to 0.7 !
terrible correlation !
Might have test BIAS: !
is the test "culture-fair" !
or do the answers require specific knowledge available only to certain (sub)
cultures? !
more than academic question !
streaming !
Dove said thee tests aren't fair bc they ask for specific knowledge which not
everyone knows !
Chitterling test - test to see if other cultures ...
Intelligence Lecture 2
Savant Syndrome !
Autism !
Theories !
!
Next time: Theories + NVB Finish Chp 10 and Pg424-428!
!
What causes savant syndrome?!
What are the symptoms of autism? !
What is intelligence?!
!
!
On owl: Atkinson has lecture on Language!! !
!
Mental age of 10 and IQ of 200. How old is he? -> 5 !
!
!
Galton!
intelligence is unitary !
is a sensory ability!
is hard wired !
