Objectives and agendaObjectivesList the definitions of intelligenceWork with the difference between intelligence and

achievementOutline the different psychological ideas of intelligenceAgendaWarm-up—answer questions on intelligenceDiscuss warm-upTake intelligence testGroup—research the following psychologist’s ideas on

intelligence—Charles Spearman, Howard Gardner, Robert Sternberg

Warm UpWhat is intelligence?List behaviors that you believe to

characteristic of intelligent people, and then behaviors characteristic of unintelligent people.

Achievement vs. Intelligence Achievement—knowledge and skills

gained from experience. Things you know and can do.

• Intelligence—abilities to learn from experience, think rationally, and to deal effectively with others and the environment.

• Intelligence makes achievement possible

Charles Spearman and The G-Factor

General intelligence (g): Spearman’s belief that there is a single factor that underlies specific mental abilities and is therefore measured by every task on an intelligence test.

Specific intelligences tended to be positively correlated.

Objectives and agendaObjectives

Know the similarities and differences between alternate ideas of intelligence

Argue whether intelligence tests are the best way to determine intelligence

List why people have different intelligencesAgenda

Warm-up--True intelligence?—Derek—Take notes and be ready to discuss from your notes if Derek is “Intelligent.

Notes on Different types of Intelligence Intelligence test—takeDiscuss different types of intelligence tests.The Real Rainman videoHomework—study guide for Unit III.

•From a biological point of view, Gardner has noted that brain damage often may diminish some abilities but not others.

•Gardner argues humans do not have one intelligence (g factor) but instead multiple intelligences which are relatively independent of the others.

Gardner’s Multiple IntelligencesGardner argues there are 9 intelligences:

1. Verbal Linguistic 2. Logical-mathematical3. Visual Spatial 4. Bodily-kinesthetic5. Auditory-musical6. Interpersonal (sensitivity to the feelings of others)

7. Intrapersonal (insight into one’s own inner feelings)

8. Existential (insight into larger picture of life ((phil.))

9. Naturalist (understanding laws that govern natural behavior)

GARDNER“Multiple Intelligences” - continued

The existence of savants, prodigies and other exceptional individuals supports Gardner’s theory:

Robert Sternberg

“The true measure of success is not how well one does in school…

…but how well one does.”

Sternberg looked to overcome the fact that although IQ tests predicted school tests relatively well, they did less well predicting vocational success.

Other IntelligencesEmotional intelligence.—5 factorsSelf-awareness—recognize own feelingsMood management—distract from uncomfortable feeling. –how long they last

Self motivation—move ahead with confidence and enthusiasm

People skills—ability to empathize, understand, communicate and cooperate

Alfred BINETCreated an intelligence test that could measure the mental age of school children

Mental age

Chronological ageX 100 = IQ

What is the IQ of:

a10-year-old with the mental age of a 12 year old?

an 8-year-old with the mental age of a 10 year old?

Mental age

Chronological ageX 100 = IQ

12

10X 100 = 120

A 10-year-old with the mental age of a 9 year old?

10

8X 100 = 125

9

10X 100 = 90

Alfred Binet and Intelligence TestsMental Age: chronological age that most typically corresponds to a given level of performance. Intelligence increased with ageA child who does as well as the average 8-year-old is said to have a mental age of 8.

Binet did not believe his test measured inborn intelligence.

Qualities of A Good TestTo be accepted all psychological tests must be:

1.Standardized2.Reliable 3.Valid

Reliability vs. Validity (DON’T MIX THEM UP)• Reliability—equals consistency

—same scores for same person at different times

Validity deals with accuracy or predictability. Asks the question does the test measure what it is supposed to measure?

Purpose of IQ test—Determine High IQ and low IQ’s

Problems with Intelligence Tests

Not perfectSome better than othersEducation and backgroundMotivationCulturally biased

Words and concepts used by particular groups

Understand meanings of some questions.Problem-solving methods

Broadening Theory of IntelligenceSavant Syndrome: a

condition in which a person otherwise limited in mental ability has an exceptional specific skill.

not guarantee creativityGifted—outstanding

Environmental Influences on IntelligenceGenetics play a role in intelligence (because

identical twins have similar IQs) but …the home environment and parenting styles can

influence IQ and;preschool programs like Head Start affect IQ as

well.SEE NEXT SLIDE

Is Intelligence Genetic or Environmental?

Influenced by both, but the most genetically similar have the most similar scores.
