Intelligence Testing
Theories of Intelligence
Types of IQ Tests
Fact or Falsehood
What is
intelligence?
Psychologists have different views on this
Most believe it is…
- the ability to acquire new ideas and new
behavior, and to adapt to new situations
Others believe intelligence is the ability to do
4 Theories of Intelligence
Two-Factor Theory of Intelligence
Thurstone’s Theory of Intelligence
Spearman’s Two-Factor Theory of Intelligence
Proposed by British psychologist Charles Spearman in 1904
States two factors contribute to intelligence
general intelligence (“g”) is a person’s ability to perform complex mental work such as problem solving
believed every individual has a certain level of general intelligence
specific mental abilities (“s”) in areas such as math or verbal skills
Criticisms of the Theory
g does not measure mental abilities such as motor, musical, or creative abilities.
Thurstone’s Theory of Intelligence (1938)
Proposed that intelligence is based on seven primary mental abilities
1. verbal comprehension 2. numeric ability 3. spatial relations 4. perceptual speed 5. word fluency 6. memory 7. inductive reasoning
A major critic of Spearman’s theory
Concluded there was no evidence of Spearman’s idea of general intelligence (g)
Sternberg’s Theory of Intelligence (1985)
Believed that traditional intelligence tests do not measure the intelligences found in everyday life
Robert Sternberg proposed a triarchic (3 part) theory of intelligence
Can be divided into 3 types of thinking skills or ways of processing information
Analytical -ability to solve problems (types of skills typically measured on intelligence tests)
Creative -dealing with new situations; solving problems in a unique way
Practical -helps us adjust to and deal with our environment
Gardner’s Theory of Multiple Intelligences
Believes traditional views of intelligence are
inadequate because it only measures the ability
to think logically & leaves out many important
skills
Calls for a broader perspective that originally
included 7 types (1983). He later added an 8
thtype and is considering adding a 9
th(existential
intelligence-experience of existence)
His research on brain disease helped him
Gardner’s Multiple Intelligences
See textbook p.351 (table 13.6) for a description & more examples of the Gardner’s intelligences.
1. Linguistic/ Verbal
2. Logical-Mathematical
3. Spatial (shapes & images-puzzles, 3-D figures)
4. Musical
5. Body-Kinesthetic
6. Interpersonal- ability to interact w/ others
7. Intrapersonal- ability to accurately perceive oneself
8. Naturalist- ability to identify/ classify patterns in nature
Criticisms of Gardner’s Theory
Some of what Gardner calls “intelligence” are
really skills (or talents).
Do not feel that it should be used in the
classroom
– critics feel children are used as “guinea pigs” to test the theory– not sufficient support
- critics argue that children must still rely on verbal & math skills to succeed in higher education & a career; so this should be the focus in the classroom
Emotional Intelligence
Related to Gardner’s concept of interpersonal and
intrapersonal intelligences
4 Major Aspects
(Mayer & Salovey,1997)
1.
Ability to perceive & express emotions accurately
and appropriately
2.
Ability to use emotions while thinking
3.
Ability to understand emotions & use this
knowledge
Types of Intelligence Tests
Stanford-Binet Intelligence Scale
-test currently used in the U.S. that Stanford University revised from French psychologist Alfred Binet’s original test developed in 1904
-compute IQ (intelligence
quotient) based on a scale in which 100 is the average.
-IQ scores in the population take the normal bell curve shape
-95% of the people score between 70-130
-only about 2% score over 130
Wechsler Tests
-WAIS-R (for adults)
-WISC-III (ages 6-16 years) -WPPSI-R (4-6 ½ years)
-give one overall score as well as separate scores for verbal & performance abilities
Controversy over IQ Testing
Do IQ scores truly measure intelligence?
Nature vs. Nurture: Do genetic differences or
environmental inequalities cause two people to
receive different scores?
--IQ scores are correlated to genetic factors
identical twins regardless of differences in
environment often have similar IQ scores
--environmental factors also play a critical role
education received, home environment, and
Cultural Bias: Criticism of IQ Testing
-
the wording used in an intelligence test may
be more familiar to people of one social
group than to another group.
Efforts have been made to make tests less
biased, but it is very difficult to completely
remove all bias. All tests assess prior

Intelligence tests help psychologists make recommendations about the kind of teaching that will benefit a child most, according to Ron
Palomares, PhD
Psychologists are taught to assess patterns of performance on intelligence tests and to obtain clinical observations of the child
during the testing session. That, he says, removes the focus from a single IQ score and allows for an assessment of the child as a
whole, which can then be used to develop individualized teaching strategies.

decisions about people," says Halpern. "We're not all the same; we have different skills and abilities. What's wrong is thinking of
"The movement that's trying to get rid of IQ
tests is failing to understand that these tests
are valid in the hands of a competent
practitioner who can go beyond the
numbers--or at least use the numbers to understand
what makes the person tick, to integrate those
test scores with the kind of child you're looking
at, and to blend those behaviors with the
