Question 1

All of the following are advantages of the Wechsler test as compared to the Binet test EXCEPT that

Accepted Answer

The Wechsler test does not largely focus on language abilities; in fact, it includes both verbal and nonverbal subtests. The other options are advantages of the Wechsler test: it can be used for adults as well as children, it provides a greater level of fairness in testing people from different language groups, and it bases the IQ score on the normal distribution instead of on a ratio, which eliminates the potential for ceiling effects.

Question 2

Which of the following is NOT a concern raised by Scarr and Gunderson about the discrepancy definition of learning disabilities?

Accepted Answer

Scarr and Gunderson raised concerns about the discrepancy definition of learning disabilities, including the exclusion of children with low intelligence who may still benefit from reading disability programs based on IQ scores (A), the possibility of ESL children with learning disabilities being missed (C), and the occurrence of the Matthew Effect (D), but they did not raise concerns about the Scarr and Gunderson effect (B), as it is not a recognized term or issue related to learning disabilities.

Question 3

Which of the following tests attempts to reduce test bias by focusing on non-verbal rather than verbal problems?

Accepted Answer

The Progressive Matrices Test is a non-verbal measure of general intelligence that attempts to reduce test bias.

Question 4

Dr.Hang has developed a new intelligence test that asks more than 300 questions.After he administers it to many separate groups,he finds that Asian-born persons who took the test did very poorly on three questions relative to Western-born persons.Dr.Hang's test should be assessed for ___.

Accepted Answer

The scenario describes item bias, which occurs when an individual or group performs differently on specific test questions due to factors such as cultural or linguistic differences. Therefore, Dr. Hang's test should be assessed for item bias. Stereotype vulnerability, gender bias, and geographical bias are not directly relevant to the scenario.

Question 5

Inzhu is ten years old and is given an IQ test.She scores above average on the test.This finding is most strongly predicted to indicate

Accepted Answer

The answer of Inzhu is ten years old and is...

Question 6

Josie works as a cashier at a restaurant.She notices that after having a customer's credit card for only a couple of minutes,she can recite the credit card number both forward and backward.Josie would likely perform very well on the ___ test of WAIS.

Accepted Answer

The digit span test assesses a person's short-term memory and ability to recall a series of numbers both forward and backward, which is exactly what Josie is able to do with the credit card number. The other options - matrix reasoning, similarities, and letter-number sequence - do not directly relate to memory or recall of numbers.

Question 7

The intelligence tests created by Wechsler were different in several ways from the Stanford-Binet.Which of the following is NOT one of these ways?

Accepted Answer

The Wechsler tests do contain a verbal component, in addition to performance tasks, while the Stanford-Binet has traditionally emphasized verbal ability.

Question 8

Oscar did very well when he took an intelligence test at the age of 10 years.Knowing this,which of the following is most likely to be true about Oscar's future?

Accepted Answer

Higher intelligence scores have been correlated with better health outcomes and longer lifespans in various studies. This is likely due to a combination of factors, including better problem-solving abilities leading to healthier lifestyle choices, higher socioeconomic status, and better access to healthcare.

Question 9

Medina,a female student,is completing the math section of an IQ test.Based on the stereotype threat concept,which of the following stereotypes is most likely to negatively affect Medina's performance?

Accepted Answer

The stereotype that "women are bad at math" is most likely to negatively affect Medina's performance according to the stereotype threat concept. This stereotype can create anxiety and undermine confidence, which can lead to reduced performance in math-related tasks.

Question 10

The year is 1917 and Ophelia,a woman of average intelligence,stumbles across a time machine and travels forward in time 100 years.If she were studied by scientists in our modern times and given an intelligence test,what is she likely to score?

Accepted Answer

Ophelia is likely to score far below what she scored 100 years ago due to the Flynn effect, which posits that there has been a significant increase in IQ scores over the 20th century, largely attributed to environmental factors such as improved nutrition, education, and access to information. Thus, the same level of intelligence would result in a lower score on a modern test calibrated to contemporary norms.

Question 11

Which of the following is NOT one of the sections of Wechsler's performance scale?

Accepted Answer

Digit span is part of the Wechsler's verbal scale, not the performance scale. The performance scale includes tasks like picture completion, object assembly, and block design, which are designed to assess non-verbal and spatial abilities.

Question 12

How well do intelligence tests predict performance?

Accepted Answer

IQ scores have a correlation to school performance of +.50, which indicates a moderate positive relationship between the two variables. However, IQ scores alone cannot fully predict academic success or other aspects of people's lives. Other factors such as motivation, personality traits, and socio-economic background also play a role.

Question 13

The Flynn effect refers to

Accepted Answer

The Flynn effect specifically refers to the increase of intelligence test scores over time. It is not related to bias in IQ testing, genetic changes, or restandardization of tests.

Question 14

Mishtaalways wins at games testing knowledge of trivia.On which index of the WAIS is Mishtalikely to perform extremely well?

Accepted Answer

The answer of Mishtaalways wins at games testing knowledge of...

Question 15

What degree of reliability is demonstrated between the WAIS and Stanford-Binet intelligence tests?

Accepted Answer

The degree of reliability between the WAIS and Stanford-Binet intelligence tests is 90%. This means there is a high level of agreement between the two tests in terms of measuring intelligence.

Question 16

On which of Wechsler's scales would a question such as "What is the Westernmost Canadian province?" appear?

Accepted Answer

The information subtest specifically measures knowledge of information obtained from formal education, informal learning, and cultural experience. The question about the Westernmost Canadian province falls under general knowledge and would appear in this subtest.

Question 17

Julianne is taking part in a research study in which she must complete a spatial task.Before she begins,the researcher tells her NOT to feel bad if she doesn't do well because females tend to have poorer spatial ability than males.How will Julianne do on the task relative to other participants who are NOT told this?

Accepted Answer

Julianne may experience stereotype vulnerability, which refers to the phenomenon where individuals from a stereotyped group may experience anxiety and perform worse on tasks when reminded of the stereotype. Thus, Julianne may perform worse compared to other participants who were not reminded of the stereotype.

Question 18

___ occurs when people in a specific group perform poorly on an IQ test because they fear that their performance will confirm a negative perception of their group.

Accepted Answer

Stereotype threat refers to the phenomenon where individuals or groups perform poorly on a task because they are aware of and conform to negative stereotypes about their group. This can lead to underperformance on IQ tests, standardized tests, and other academic tests. This is not the same as biased testing or culture-specific test construction, which refer to issues with the test itself rather than the test taker. Stereotype vulnerability is a similar concept, but it refers to the broader impact of stereotypes on an individual's self-concept and well-being.

Question 19

Wechsler designed his intelligence tests to be different in several ways from the Stanford-Binet test.Which of the following statements about these differences is FALSE?

Accepted Answer

This statement is false. The Wechsler tests do contain a verbal component in addition to a performance component.

Question 20

Which of the following scales is part of Wechsler's verbal scale?

Accepted Answer

Arithmetic is part of Wechsler's verbal scale. The other options, picture completion, digit symbol, and object assembly, are part of Wechsler's performance scale.
