Question 1

What was the Ravens' Progressive Matrices Test designed to do?

Accepted Answer

The Ravens' Progressive Matrices Test was designed to minimize the influence of background knowledge on intelligence assessment. It assesses abstract reasoning and problem-solving abilities without relying on language or cultural knowledge.

Question 2

Tests can be used to facilitate some hiring decisions, but errors will always occur. This is because __________.

Accepted Answer

Predictive validity, which measures the accuracy of a test in predicting job performance or other relevant outcomes, is never perfect. Even the most successful tests have a certain margin of error, which means that some candidates who perform poorly on the test may still be a good fit for the position, while others who perform well may not be successful on the job. Therefore, hiring decisions based solely on test results may not always be accurate.

Question 3

"That's so not true! This test can't have anything to do with my ability to attract women!" Ignacio protests. Ignacio is disputing the test's __________.

Accepted Answer

Ignacio is disputing the validity of the test, which refers to the degree to which the test measures what it claims to measure. In this case, he is arguing that the test cannot accurately measure his ability to attract women. Option A, predictive ability, refers to the degree to which the test can accurately predict future performance or behavior, which is not being disputed by Ignacio. Option B, norms, refers to the average performance of a group of people who have taken the test, which is not relevant to Ignacio's statement. Option D, reliability, refers to the consistency of results over time or across different test versions, which is also not being disputed by Ignacio in this statement.

Question 4

Dr. Munakata subscribes to a psychometric view of intelligence. This means that she believes that intelligence may be best understood by __________.

Accepted Answer

A psychometric view of intelligence focuses on analyzing correlations among tests of specific abilities, suggesting that intelligence is a measurable construct that consists of different cognitive abilities.

Question 5

The predictive validity of most scholastic aptitude tests is in the neighborhood of 0.55. This suggests that __________.

Accepted Answer

A predictive validity of 0.55 indicates that factors other than scholastic aptitude also influence academic performance. This means that although the scholastic aptitude test may be a good indicator of academic ability, it is not the only factor that determines academic success.

Question 6

Lassandra's scores on different parts of an IQ test are very different from one another. Lassandra's profile of scores on this test __________.

Accepted Answer

Binet's view of intelligence was that it was a singular, general ability. Thus, if someone's scores on different parts of an IQ test vary significantly, it contradicts his view because it suggests multiple areas of ability rather than a single, unified intelligence.

Question 7

An online intelligence test yields a different IQ each time you take it. The test is __________.

Accepted Answer

A test that yields different results each time it is taken indicates low reliability, which means the test is not consistent in measuring what it intends to measure. This calls into question its validity as well, as a test must be reliable in order to be valid. Therefore, B is the best choice.

Question 8

A mental test is considered reliable if __________.

Accepted Answer

Reliability refers to the consistency and stability of a test's scores. Therefore, a mental test is considered reliable if it consistently measures whatever it measures, regardless of whether it measures the characteristic it was designed to measure or if the scores obtained on the test are accurate measures of the characteristics in question. Option D is incorrect because test scores can vary due to factors such as practice effects or changes in the individual's cognitive abilities.

Question 9

How might Binet react to Spearman's concept of g?

Accepted Answer

Binet would endorse Spearman's concept of g because it is consistent with his own view that intelligence is a general factor that underlies all cognitive abilities.

Question 10

Based on years of research, what can we comfortably assert about IQ and reliability?

Accepted Answer

Based on years of research, we can comfortably assert that score at age 6 correlates with score at age 18, indicating a high level of IQ reliability over time.

Answer: B and C are incorrect. 
 There is no evidence to support the claim that the older we get, the dumber we become, nor is there evidence to support the claim of no correlation between childhood IQ and IQ in adulthood. These claims are not supported by research.

Answer: D is incorrect. 
 IQ tests have been shown to be valid and reliable measures of cognitive ability.

Question 11

"Every time I take it, it tells me something different!" complains your friend, turning away from the online personality quiz she just completed. Your friend is complaining about the test's __________.

Accepted Answer

Reliability refers to the consistency of results obtained from a test. If your friend is getting different results each time she takes the quiz, then the test is not reliable since it is not providing consistent results.

Question 12

Dr. Williams has developed a paper-and-pencil test to assess fear of heights. He gives the test to 50 research participants, whose scores range from 0 (no fear) to 100 (intense fear). He finds that scores on the test have a correlation of only -0.25 with physiological measures of fear. Two months later, participants take the paper-and-pencil test again. The correlation between scores on this second paper-and-pencil test and scores on the first paper-and-pencil test is 0.95. This information suggests that Dr. Williams' test is __________.

Accepted Answer

The correlation between the paper-and-pencil test scores and physiological measures of fear is low, indicating that the test may not be valid. However, the high correlation between the two administrations of the test suggests that the test is reliable. Therefore, the best choice is D, which indicates that the test is probably not valid but reliable.

Question 13

A test is considered valid if __________.

Accepted Answer

A test is considered valid if it measures the characteristics that it was designed to measure. Validity is related to the accuracy and relevance of the inferences based on the test scores. It is important for a test to measure what it's meant to measure in order to make accurate predictions or decisions based on the test results.

Question 14

Dr. Nguyen believes that intelligence consists of multiple, specialized abilities. Which pattern of correlation coefficients might she expect when she examines scores on an intelligence test containing verbal, numerical, and spatial subtests?

Accepted Answer

Dr. Nguyen's belief in multiple, specialized abilities suggests she would expect low correlations between different types of intelligence, indicating that each is distinct. Option D shows low correlations across all pairs, consistent with this view.

Question 15

If intelligence is a unitary phenomenon, rather than a diverse collection of specialized abilities, then one might expect __________.

Accepted Answer

If intelligence is a unitary phenomenon, then one would expect little variability in scores across the different components of an IQ test, as all the components would measure the same underlying general intelligence factor. This is opposed to the idea that intelligence is a diverse collection of specialized abilities, which would result in more variability in scores across different components of an IQ test.

Question 16

The extent to which a test measures what it is designed to measure is known as the test's __________.

Accepted Answer

Validity refers to the degree to which a test measures what it claims to measure, while criterion measure refers to the standard against which a test is evaluated, norms refer to the score distribution within a particular population, and reliability refers to the consistency of test results over time. Thus, D is the best choice as it directly relates to the definition provided in the question.

Question 17

In order to assess whether intelligence is a unitary phenomenon or consists of multiple specialized components, a researcher using the psychometric approach would determine the __________.

Accepted Answer

The psychometric approach focuses on analyzing the correlations among different tests of specific abilities in order to determine whether intelligence is a unitary phenomenon or consists of multiple components. The approach seeks to identify the underlying structure of intelligence by examining patterns of performance on different tasks.

Question 18

The approach to intelligence that arises from looking at test scores is called the __________ approach.

Accepted Answer

The psychometric approach emphasizes the importance of measuring and quantifying intelligence through standardized tests and has traditionally been the dominant approach in psychology.

Question 19

A researcher administers a certain intelligence test to a large sample of adults. The test contains verbal, numerical, and spatial subtests. The researcher finds a correlation coefficient of .15 between verbal and numerical scores, a correlation coefficient of .75 between numerical and spatial scores, and a correlation of .10 between verbal and spatial scores. How might the researcher interpret this pattern of results with respect to (i) the view that intelligence is a unitary ability and (ii) the idea that intelligence consists of multiple, independent, specialized abilities?

Accepted Answer

The answer of A researcher administers a certain intelligence test...

Question 20

A big question addressed by the psychometric approach is whether intelligence is __________.

Accepted Answer

The psychometric approach examines the structure of intelligence and assesses whether it is a single factor or composed of multiple components. Therefore, A is the best choice for this question. B and C are incorrect because the psychometric approach does not focus on inheritance or environment as the main determinants of intelligence. D is incorrect because the psychometric approach is not confined to mathematical abilities but encompasses all aspects of intelligence.
