the reliability of a test can vary from

0 to 1

what is the mean IQ score on the Stanford-Binet test?

100

according to Raymond Cattell, the "g" factor in intelligence has two major components:

Fluid and crystallized

why do deaf and foreign-born people get a fair score on the Raven's progressive Matrices than they do on the Wechsler or Stanford-Binet test?

Raven's Matrices include only nonverbal questions and answers.

the researches associated with developing the triarchic theory is

Robert Sternberg

the early ID test developed in France and modified for English speakers became the first important IQ test in the English language. this new version was the

Stanford-Binet.

what IQ test has separate parts that measure verbal comprehensions, perceptual reasoning, working memory, and processing speed.

WISC-IV

IQ test were originally devised to help identify

children who belonged in special classes

according to Strenberg's triarchic theory, in order to understand intelligence we much consider the situation that require intelligence, how intelligence relates to the outside world, and the

cognitive processes within the individual

Extensive practice at computer programming improves that skills without much effect on any other kind of performance. therefore we classify the improved programming skill as

crystallized intelligence

an experience taxi driver becomes more skilled at finding various addresses within a city, without improving other intellectual skill. we can say that the driver has increased his or her.

crystallized intelligence

Raven's progressive Matrices represent an attempt to construct a

culture-reduced IQ test

in contracts to an achievement test, an aptitude test is intended to measure what?

fluid intelligence

A new worker at Consolidated generic product cannot perform any of the company's traditional tasks as well as more experienced works. However, the new worker learns new skills faster than the older workers. the new worker apparently has a high degree of

fluid intelligence.

When Spearman described the "g" factor in intelligence, what did the "g" stand for?

general

according to Cattell, if we examine the intelligence of a person at age 20 and again at age 50, we are more likely to fins

gradually increasing levels of fluid intelligence

on a new test of academic ability, people who get high scores on time generally get high scores the second time. However, students who do well on this test are not much more likely (nor less likely) than other students to do well in school. Therefore the test has ___ reliability and ___ validity

high..low

if people of different generations took the same IQ test, standardized long ago and not re-standardized, today's young adults would score on the average:

higher than their parents or grandparents

what does the validity of a test indicate

how well it predicts some kind of performance

The WAIS-III and the WISC-IV are tests of

intelligence

Psychologists analyze a test to see whether its content matches the purpose of the test. The answers to this question pertain to which aspect of the test?

its validity

how many genes apparently produce some effect on human intelligence?

many, at least dozen

adopted children generally have IQ scores ___ similar to those of their biological parents than to those of their adoptive parents. The similarity in IQ to the biological parents___ as these adopted children grow older.

more.. increase

Identical twins typically are ___ similar in intelligence than fraternal twins; fraternal twins typically are ))) similar in intelligence than single birth siblings.

more...more

what is true of an item on the Stanford-binet IQ test designated as "age 8"

most 8 year olds answers correctly.

what is the main assumption of Howard Gardner's theory of multiple intelligence?

people have a number of unrelated form of intelligence

what is evidence, if found, would offer the strongest support in favor of Gardener's theory of multiple intelligence?

people with high scores on ability tend to get high scores on other abilities

Two standard ways to evaluate a test are to measure its ___ and its ___

reliability..validity

A psychologist who gives a group of people the same test several times is probably trying to measure the ____ of the test?

standard deviation

If an IQ test is valid, what should its score be able to predict?

success in school

How strongly do monozygotic twins resemble each other in IQ if they were reared in separate families?

they resemble each other a little less than brother and sister reared together

what was originally, and still is the main purpose of IQ tests?

to predict performance in school.

in order to determined the reliability of a test, an investigator determines

weather the items on the test represent the topic that test is supposed to cover

to determine the validity of an IQ test, we measure

weather the score correlate positively with grades in high school
