Intelligence
• The ability to learn from experience, solve problems, and use knowledge to adapt to a new situation
• Is socially constructed thus…
Can be culturally specific.
According to this definition, are both Einstein and Ruth intelligent?

Is Intelligence one thing or Several
different abilities?
• To find out scientist use FACTOR
ANALSYSIS:
– A statistical procedure that identifies
clusters of related items on a test
– Charles Spearman used FA to
discover his g or (general
intelligence).
• He saw using FA that doing well in
one area of a test predicted that you
will do well in another
Jack Bauer is good at torturing, bomb defusing, shooting, figuring out evil plots and saving the country (and he is good looking). Is there anything he cannot do?

Are there multiple intelligences?
• Howard Gardner (1943- ) disagreed with
Spearman’s g and instead cameup with the
concept of multiple intelligences
• He came up with the idea by
studying savants �A condition
where a person
has limited
mental abilities
but is
exceptional in
one area

Origins of Intelligence testing
• Intelligence Test
– a method of assessing an individual’s mental aptitudes and comparing them to those of others, using numerical scores
![Page 19: Intelligence - Weber School Districtblog.wsd.net/rejohnson/files/2012/01/Ch-11.pdf · Are there multiple intelligences? • Howard Gardner (1943- ) disagreed with ... • Play “Pros](https://reader036.vdocuments.mx/reader036/viewer/2022062504/5ac53eb77f8b9aa0518de0cd/html5/thumbnails/19.jpg)
• Alfred Binet (1857-1911)
– Developer of the first test to classify
children’s abilities using the concept of
mental age
– Mental age
• The chronological age that
corresponds to the difficulty of the
questions a child can answer
• Child who does as well as the
average 8-year-old is said to have
a mental age of 8

• Lewis Terman (1877-1956)
–Adapted Binet’s tests for use in the
United States as the Stanford-Binet
intelligence test
–The test reported intelligence as a
calculated IQ score.
• Side note: Terman promoted use of
intelligence testing to encourage or
discourage people from reproducing

• Intelligence Quotient (IQ)
– IQ = (MA/CA) X 100
– On contemporary tests, the average performance for a given age is assigned a score of 100
– Works great for children, but not for adults
• A 50 yr old does as well as a 25 yr old
would have an IQ of 50?
– Technically there is no longer an intelligence quotient, but we still use the term IQ.

assess what a person
has learned

Assessing Intelligence
• David Wechsler (1896-1981)
–Wechsler intelligence scales
• Wechsler Adult Intelligence Scale (WAIS)
• Wechsler Intelligence Scale for Children (WISC)
• WAIS (most widely used today)
–Includes 11 subtests
–Gives overall intelligence score, but also separate verbal and performance (nonverbal) scores

How do we construct Intelligence tests?
Tests must be:
• Standardized
• Reliable
• Valid

Assessing Intelligence
• Standardization
– Test must be pre-tested to a
representative sample of
people
– Form a normal distribution
• Normal Curve (Normal distribution/Bell Curve)
– The symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes
– Most scores fall near the average, and fewer and fewer scores lie near the extremes

• Performance on IQ scores has steadily
increased over generations
• Known as the Flynn Effect
– Environmental factors?
• Reduction in
malnutrition
• Access to
schooling
• Technological
advances

Assessing Intelligence
• Reliability
– The extent to which a test yields consistent
results over time
– Assessed by consistency of scores on:
• Two halves of the test (split-half)
• Alternate forms of a test
• Retesting
• Validity
– The extent to which a test measures or
predicts what it is supposed to

Assessing Intelligence
• Content Validity
–The extent to which a test samples the
behavior of interest
• Driving test that samples driving tasks
• Criterion
–Behavior (such as college grades) that a
test (such as the SAT) is designed to
predict
–The measure used in defining whether the
test has predictive validity

Assessing Intelligence
• Predictive Validity
–Success with which a test predicts the
behavior it is designed to predict
–Assessed by computing the correlation
between test scores and the criterion
behavior
–Also called criterion-related validity

Brain Size and Intelligence
Is there a link?
• Small +.15 correlation
between head size and
intelligence scores (relative to
body size).
• Using an MRI we found +.44
correlation with brain size and
IQ score.

Brain Function and intelligence
• Higher performing
brains are less active
than lower performing
brains (use less
glucose).
• Neurological speed is
also a bit quicker.

does intelligence change over time?
•By age 3, a child’s IQ
can predict adolescent
IQ scores.
•Depends on the type of
intelligence, crystallized
or fluid.
(fluid = flexibility)(crystallized = concrete)
