Intelligence This week you took an IQ test.
Did you notice what it was really measuring? Did you need to have passed calculus to answer the math questions? Did you have to have speed-reading skills and a college-level vocabulary to do the verbal part? Were the spatial relationship questions just there to see how well you could draw? Did it ask you what your class rank and GPA were? Why Not?

Origins of Intelligence Testing
ability to learn from experience, solve problems, and use knowledge to adapt to new situations
4
Origins of Intelligence Testing
Mental Age a measure of intelligence test performance devised by Binet chronological age that most typically corresponds to a given level of performance child who does as well as the average 8-year-old is said to have a mental age of 8
5
Origins of Intelligence Testing
Stanford-Binet the widely used American revision of Binet’s original intelligence test revised by Terman at Stanford University
6
Origins of Intelligence Testing
Intelligence Quotient (IQ) defined originally the ratio of mental age (ma) to chronological age (ca) multiplied by 100 IQ = ma/ca x 100 Ex: 18/12 x 100 = 150 on contemporary tests, the average performance for a given age is assigned a score of 100 Established by giving thousands of tests to thousands of people to establish an ‘average’ for a given age Scores can change over time, but generally they do not vary more than 5 points.

What is Intelligence? Factor Analysis General Intelligence (g)
statistical procedure that identifies clusters of related items (called factors) on a test used to identify different dimensions of performance that underlie one’s total score General Intelligence (g) factor that Spearman and others believed underlies specific mental abilities measured by every task on an intelligence test
8
Are There Multiple Intelligences?
Savant Syndrome condition in which a person otherwise limited in mental ability has an exceptional specific skill computation drawing
9
Are There Multiple Intelligences?
Social Intelligence the know-how involved in comprehending social situations and managing oneself successfully Emotional Intelligence ability to perceive, express, understand, and regulate emotions
10
Intelligence and Creativity
the ability to produce novel and valuable ideas expertise imaginative thinking skills venturesome personality intrinsic motivation creative environment
11
Assessing Intelligence
Wechsler Adult Intelligence Scale (WAIS) most widely used intelligence test subtests verbal performance (nonverbal)
12
Assessing Intelligence
Aptitude Test a test designed to predict a person’s future performance aptitude is the capacity to learn Achievement Test a test designed to assess what a person has learned
13
Assessing Intelligence
Standardization defining meaningful scores by comparison with the performance of a pretested “standardization group” Normal 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
14
The Normal Distribution Curve
15
Assessing Intelligence
Reliability the extent to which a test yields consistent results assessed by consistency of scores on: two halves of the test alternate forms of the test retesting Validity the extent to which a test measures or predicts what it is supposed to IQ tests are now being studied for culture and gender bias in their questions
16
Assessing Intelligence
Content Validity the extent to which a test samples the behavior that is 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
17
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
18
The Dynamics of Intelligence
Mental Retardation a condition of limited mental ability indicated by an intelligence score below 70 produces difficulty in adapting to the demands of life varies from mild to profound Down Syndrome retardation and associated physical disorders caused by an extra chromosome in one’s genetic makeup
19
“Giftedness” Not necessarily a “high achiever” who works hard and does well in school Exceptional attributes and achievements, but not ‘giftedness’ Involves more than excellence in tasks Distinct difference in functioning: music, math, movement Not just really good at something: they are exceptional. This difference often causes social difficulties in finding like-minded people. (Einstein was considered downright weird…) Because they may not be achieving at a standard others expect, some unidentified gifted children are ‘identified’ as “problem children.” Giftedness occurs in less than 1% of the population.

The Dynamics of Intelligence
21
Where Intelligence Comes From: Genetic Influences
The most genetically similar people have the most similar scores
22
Genetic Influences Heritability
the proportion of variation among individuals that we can attribute to genes variability depends on range of populations and environments studied
23
Genetic Influences
24
Environmental Influences
The Schooling Effect
25
Environmental Influences
Social environment Class which provides early enrichment and experiences Style of parenting General home environment Is goal-setting encouraged? Is the child driven to improve themselves? Stereotype Threat A self-confirming concern that one will be evaluated based on a negative stereotype
