Deck 10: Intelligence

Question 1

Ted was bored by school, so his grades were poor throughout primary and secondary school. He eventually dropped out and started a business rebuilding classic cars with modern engines. Ted's business is very successful, and he loves what he does. Is Ted intelligent?

A) No. Good grades are the best indicator of intelligence.
B) Yes. People who are bored in school invariably have genius-level IQs.
C) No. Ted has not demonstrated an ability to acquire knowledge, reason effectively, and adapt to his environment.
D) Yes. Ted has demonstrated an ability to acquire knowledge, reason effectively, and adapt to his environment.

Answer 1

Yes. Ted has demonstrated an ability to acquire knowledge, reason effectively, and adapt to his environment.

Question 2

Alfred Binet was commissioned to develop the first true intelligence test. The test was intended to be^{(p. 334} used to- 335)

A) identify schoolchildren who would need remedial help as early as possible.
B) predict which soldiers would make the best officers in the military.
C) predict which children would grow up to be great artists, musicians, and writers.

Answer 2

identify schoolchildren who would need remedial help as early as possible.

Question 3

Margaret took the Wechsler Adult Intelligence Scale (WAIS-III) and was told that she has an IQ of 90. Margaret is certain this proves that her teachers are grading her unfairly when they give her C's. Margaret's friend Latisha explained that an IQ of 90 is not the same as a grading of 90 percent. Instead, it means that Margaret's

A) score is actually at the 9^th percentile, which suggests that she is developmentally disabled.
B) score is actually above the 90^th percentile and her IQ is very high.
C) IQ test was invalid, since it is not possible to get a 90.
D) score falls at about the 25^th percentile, and her IQ is slightly below average.

Answer 3

score falls at about the 25^th percentile, and her IQ is slightly below average.

Question 4

Larry tells you his 10-year-old cousin recently completed the Wechsler Intelligence Scale for Children(WISC-IV). Larry knows his cousin's score was 120, but he is not sure what this means. You shouldtell him that his cousin

A) scored lower than average for 10-year-olds.
B) answered 120 questions correctly on the test.
C) scored higher than average for 10-year-olds.
D) scored like an average 10-year-old.

Question 5

Monica recently completed the Wechsler Adult Intelligence Scale (WAIS-III) and was told that her IQ falls at the 50^th percentile. This means that

A) her score falls below the average for the test.
B) her IQ score is 100.
C) her IQ score is 50.
D) she

Question 6

Seamus grew up in an impoverished neighborhood with a lot of crime and poor educational opportunities. Because everyone fought over the few available resources, sometimes the only way to stay alive was to fight or steal. Seamus wants to go to college so he can build a better life for himself. When he begins taking classes, he's stunned by how little in the way of "street smarts"his classmates have. They might get better grades than he does, he thinks, but they wouldn't survive a week in the environment in which he grew up. About which kind of intellectual competence is Seamus thinking?

A) analytical intelligence
B) creative intelligence
C) practical intelligence
D) metacomponents

Question 7

Spence just received his IQ report, and his Full-Scale IQ is 110. The tester tells him that his score must be considered in context; that is, his IQ is a comparison of his score to the scores of

A) people of all ages in the United States.
B) everyone in North America over the past 100 years.
C) the scores of people in all countries and of all ages.
D) all his peers (people who are about the same age).

Question 8

When Janine takes the personality test in the latest issue of Appeal magazine, her scores suggest that she is kind, generous, and caring. When she retakes the test later that week with several friends, her scores suggest she is self-centered, vain, and competitive. Janine's wildly different scores suggest a significant

A) test-retest reliability.
B) criterion validity.
C) amount of internal consistency.
D) lack of test-retest reliability.

Question 9

Laoghaire and Ryu are research assistants in a developmental psychology laboratory. They are to watch several hours' worth of video footage and code the various interactions. Laoghaire codes tapes 1 to 25 while Ryu codes tapes 26 to 50. When they are finished, they switch tapes so that Laoghaire can code tapes 26 to 50 and Ryu can code tapes 1 to 25. Neither is allowed to see how the other is coding until all the tapes have been coded by both of them. If Laoghaire and Ryu code in a similar fashion, the coding measurement will have

A) interjudge reliability.
B) internal consistency.
C) content validity.
D) longevity.

Question 10

Mr. Gannon tells his class that he is going to give them an intelligence test. The test, he says, is only a page long and will accurately tell him whether or not each student has a high IQ. When Moira receives her copy of the test, she sees that the questions include items like "Mr. Gannon is the best teacher I've ever had"and "I tell my parents what a good job Mr. Gannon does when he is teaching me."Clearly, Moira thinks, this test has little

A) internal consistency.
B) crystallized intelligence.
C) construct validity.
D) criterion-related validity.

Question 11

If you chart the IQ scores of every living American, the statistical distribution will look like a

A) normal distribution or bell curve, with most scores clustering around the middle.
B) bimodal distribution, with most scores falling at the higher and lower ends.
C) skewed distribution, with most scores falling at the higher end.
D) flat distribution, with an equal number of people having each level of intelligence.

Question 12

Albert Einstein's brain was smaller than average, but some parts had extremely dense neural networks. One theory suggests that the ability to establish new neural networks increases processing speed and efficiency and, therefore, intellectual skills. In other words, individual differences in __________ maybe key.

A) brain size
B) brain plasticity
C) the brain's production of serotonin
D) the occipital lobe's functioning

Question 13

Identical twins raised in the same homes have IQs correlated at about .86. Identical twins raised apart have IQs correlated at about .75. Unrelated adopted children raised in the same home have IQs correlated at about .32. Based on this information and research on the heritability of intelligence, we can say that __________ of the population variability in intelligence can be attributed to theenvironment.

A) between a quarter and a third
B) half
C) most
D) very little

Question 14

Carla and Brad are competing for a job. Both are qualified for it, and they have equivalent backgrounds and experience. Before the last series of interviews, they are asked to complete a battery of aptitude and intelligence tests. When Brad comments to Carla that men excel on these types of tests, Carla feels flustered, particularly since all the people who previously held the position were men. Carla is experiencing

A) stereotype threat.
B) achievement anxiety.
C) just enough stress to increase her test scores.
D) entity increments.

Question 15

People with undiagnosed learning disabilities, or those who have not learned to accommodate, do not, by definition, perform as well on tests as their IQs suggest they should. Unfortunately, many people view achievement tests as if they were aptitude tests, and therefore assume that people with learning disabilities are less intelligent than they really are. This underestimation is called an

A) aptitude bias.
B) achievement bias.
C) ability bias.
D) outcome bias.

Question 16

Clint recently began school, and he is having trouble with reading, writing, memory, and mathematical computation. He isn't very good at reasoning, planning, and evaluating feedback from others, and he needs others to help him solve problems. His family has him tested for mental disabilities, and the school psychologist reports that Clint's IQ is 61. This means that Clint is

A) gifted, but not applying himself adequately.
B) struggling with a learning disability. If accommodations are made for the disability, his IQ will rise to around 100.
C) mildly cognitively challenged, developmentally disabled, or mentally retarded.
D) severely mentally retarded.
