Flashcards in chapter 9 Deck (48):
1

sir francis Galton

earliest attempts to measure intelligence
British mathematician
he had the idea the high intelligence emerged from possessing unusually keen sensory abilities since we must acquire all of our knowledge through sensory experience.

2

anthropometrics

the measurement of people.
methods of measuring physical and mental variation in humans

3

James mckeen Cattell

proved with university students that sir Francis Galton theory was false

4

intelligence

an ability to think, understand, reason, and adapt to or overcome obstacles

5

Alfred Binet and Theodore Simon

they figured that intelligence was not really a matter of sensory ability
instead they proposed the differences in intelligence should be thought of as reflecting differences in more complexed mental abilities such as memory, attention, and language comprehension

6

mental age

the average intellectual ability score for children of a specific age

7

Lewis Terman

modified Binet's and Simon's test, he called it the Standford-Binet's test succeeded in selling his intelligence test to the US military during WW1 and afterwards to the US public school system to prepare the kids for university.

8

Standford-binet's intelligence test

a test intended to measure innate levels of intelligence

9

intelligence quotient (IQ) William Stern

a person's intelligence might be well captured by a single number
equals: mental age/chronological age *100

10

deviation IQ

calculated by comparing the persons test score with the average score for people of the same age. it stops the theory that IQ declines as a person gets older.

11

social Darwinism

the idea of eugenics which means good genes

12

eugenics was a movement that promoted __

preventing people from reproducing if they were deemed to be genetically inferior so as to improve the human gene pool

13

Terman's words

high grade or borderline deficiency is very common among Spanish-indian and Mexican families of the southwest and also among negroes
their dullness seems to be racial, or at least inherent in the family stocks from which they come

14

meritocracy

people who had the most ability an worked the hardest who relieve the most wealth and power status

15

the testing situation is inherently culturally-biased because.....

members of different ethnic groups vary in how comfortable they are in formal testing situation, with test administrators and in their motivation to perform well

16

stereotype threat

occurs when negative stereotypes about a group cause group members to underperform on ability tests.

17

incremental theory

the belief that a person's intelligence can be shaped by experiences practise and effort

18

entity theory

the belief that intelligence is a fixed characteristic and relatively difficult or impossible to change

19

what is the problem with the Standford-Binet and WAIS intelligence tests

the have questions related to culture (culturally biased)

20

what does the full scale IQ consist of

1. the general ability index (GAI)
- a measure of performance on verbal comprehension and perceptual reasoning tasks
2) the cognitive proficiency index (CPI)
- a measure of working memory capacity and processing speed

21

Charles spearman

spent a lot of time working with correlations and In the process he developed a technique called factor analysis. believed that some peoples brains are more powerful than others making them have more mental energy

22

factor analysis

the value of this technique is that it allows psychologists to figure out whether groups of variables cluster together
usually foot size can be correlated to body size

23

general intelligence factor (g)

represented as a persons mental energy reflecting his belief that some peoples brains are simply more powerful than others

24

is g real or can predict anything

can predict important phenomena ie) how long you are likely to live.

25

louis Thurstone

investigated the concept of g more carefully and identified that it was actually made up of 7 independent clusters of primary mental abilities

26

what are the 7 independent clusters

1.memory
2. numeric abilities
3. spatial visualization
4. perceptual speed
5.word fluency
6.verbal comprehension
7. reasoning

27

fluid intelligence (gf)

the ease by which we can learn new information and find solutions to unfamiliar problems

28

crystalized intelligence

our ability to use our past experience knowledge we have already acquired to complete tasks

29

Robert sternberg

tried to capture forms of intelligence that were different from the ones that promote success in academic settings
- Sternberg's trrchic theory of intelligence

30

what are the 3 components of Sternberg's trairachic theory

1. analytic (book smarts)
- academic type of intelligence that most intelligence tests measure
2. creative (creativity)
- flexible problem-solving in the real world beyond the classroom. ex: how to pay bills
3. practical (street smarts)
- the ability to solve completely new problems and to generate unique ideas.
- scientists need to have a high level of practical intelligence

31

Howard Gardner

proposed that there are 8 different forms of intelligence each independent from the others.

32

what are 8 unique independent of intelligence

1. verbal
2. musical/rhythmic
3. bodily/kinesthetic
4. intrapersonal - researcher novelist
5. interpersonal- politician
6. existentialist
7. visual/patial
8. logical/mathematical

33

Gender differences in intelligence

overall scores on IQ tests are statistically equal for males and females..
- females score higher on average on verbal measure of intelligence and males score higher on tests of visuospatial abilities.

34

twin and adoption studies

IQ scores of identical twins that are raised apart from one another is higher than fraternal twins who are raised together.
- genetic siblings raised together is higher than for adoptive siblings raised together.

35

environmental influences on IQ scores

tend to be dominate influence on any trait whenever there is variation in the environments that host our development.

36

behavioral genomics

examines how specific genes interact with the environment to influence behaviors including those related to intelligence to genes related to learning and problem solving.

37

gene knockout studies

have identified a number of genes related to cognitive abilities in mice.

38

transgenic studies

when scientists insert genetic material into an animals genome.

39

how does birth order affect IQ scores

the 1st born usually has a higher IQ scores than the kids born after.

40

socioeconomics status and IQ scores

children with wealthier families tend to have a higher IQ than those from a poorer families.

41

what is a family's wealth is positively correlated with

the number of books, magazines, and newspapers they own which provide them to explore the outside world of home.

42

how does stress impair mental development and functioning

-stress elevates cortisol levels, which impairs cognitive functioning
- stress also impairs memory functions at the neurological level
- stress robs mental resources that are essential for acquiring knowledge and skills in school

43

nootropic substances

substances that are believed to beneficially affect intelligence. can increase arousal and alertness. Ritalin and Provigil are used

44

the Flynn effect

refers to the steady population level increases in intelligence test scores over time. rise about 1 point every 3 years

45

who has influenced the view of intelligence to this day

Alfred binet

46

what is the Wechsler Adult intelligence sale (WAIS)

a developed IQ test that was specialized for adults and is still the most common test for adults

47

Ravens progressive matrics

an intelligence test that is based on pictures not words thus making it relatively unaffected by language or cultural background.

48

what is idiosyncratic knowledge

helps you answer that particular question or the amount of attention available to focus on the question In the moment
