Question 1

Raven's Progressive Matrices can be used to measure intelligence of people who speak other languages.

Accepted Answer

Raven's Progressive Matrices are a non-verbal test, which means that it does not require language proficiency. As a result, it can be used to measure intelligence in individuals who may speak a language other than the language in which the test is administered.

Question 2

Aptitude is similar to fluid intelligence,and achievement is similar to crystallized intelligence.

Accepted Answer

Aptitude is a measure of the ability to learn and solve problems, similar to fluid intelligence, while achievement is a measure of the knowledge and skills acquired through experience and education, similar to crystallized intelligence.

Question 3

The Wechsler Intelligence Scale for children (WISC-IV)provides subscores that call attention to a child's relative strengths and weaknesses.​

Accepted Answer

The statement is true. The WISC-IV provides subscores that allow for identification of a child's relative strengths and weaknesses in different cognitive areas.

Question 4

T​oday's young people do better than their parents or grandparents did on IQ tests.

Accepted Answer

This statement is generally true and is known as the Flynn effect, named after psychologist James Flynn. Studies have shown that average IQ test scores have been steadily increasing over the years, with each generation performing better than the previous one. However, it's important to note that IQ tests measure only certain types of cognitive abilities and are not a comprehensive measure of intelligence.

Question 5

Research has demonstrated the importance of determining a child's learning style and then educating some children visually and others verbally.

Accepted Answer

Research suggests that the concept of learning styles, such as visual or verbal learners, is a myth and that there is little evidence to support the idea that teaching to a student's preferred learning style improves learning outcomes. Effective teaching methods usually benefit all learners, regardless of their supposed learning style.

Question 6

Doing well on a standardized test requires specialized abilities different from those of other tests.

Accepted Answer

Standardized tests measure a range of skills and knowledge that are also applicable to other forms of testing, such as critical thinking, problem-solving, and understanding of material, rather than requiring a completely unique set of abilities.

Question 7

We can use IQ scores to explain why one child does better in school than another child does.

Accepted Answer

IQ scores are not the only factor that determines academic performance. There are many other factors such as motivation, study habits, learning style, and socio-economic background that contribute to a student's success in school. Therefore, it is false to say that IQ scores can explain why one child does better in school than another child does.

Question 8

​In most cases,fluid intelligence continues to increase throughout a person's lifetime.

Accepted Answer

In general, fluid intelligence tends to peak in early adulthood and then gradually decline as a person ages. However, research suggests that engaging in cognitively demanding activities and continuing to learn new things may help to mitigate the decline in fluid intelligence.

Question 9

Intelligence quotient (IQ)tests try to predict an individual's performance in school and similar settings.

Accepted Answer

IQ tests are often used to predict an individual's academic success and ability to perform well in similar settings. However, it is important to note that while IQ tests do measure certain types of intelligence, they do not provide a complete or comprehensive assessment of an individual's abilities or potential.

Question 10

​The first intelligence tests were based on decades of research on learning,memory,and cognition.

Accepted Answer

The first intelligence tests, developed by Alfred Binet and Théodore Simon in the early 20th century, were primarily designed to identify students who needed special help in coping with the school curriculum, not based on extensive research on learning, memory, and cognition.

Question 11

Genetic differences have a bigger influence on IQ differences for impoverished children than for middle-class children.

Accepted Answer

For impoverished children, environmental factors such as access to nutrition, educational resources, and stable living conditions play a larger role in influencing IQ differences than genetic differences. In contrast, in more affluent and stable environments where these basic needs are met, genetic differences have a more pronounced impact on IQ variations.

Question 12

On average,girls get higher scores on IQ tests than boys do.

Accepted Answer

There is no conclusive evidence to support this statement. Both genders have the ability to score equally high on IQ tests. Any perceived gender differences in IQ may be due to cultural and societal factors such as education and upbringing rather than innate intelligence.

Question 13

A five-year-old who has a Stanford-Binet IQ score of 116 is more intelligent than an eight-year-old who also scores 116.

Accepted Answer

IQ scores, such as those from the Stanford-Binet test, are age-adjusted. This means a score of 116 represents the same percentile of intelligence within each age group, not a higher level of absolute intelligence in a younger child compared to an older child.

Question 14

People who do well on one cognitive test generally do well on other cognitive tests also.

Accepted Answer

This is generally true, as cognitive abilities tend to be correlated. However, it is important to note that different cognitive tests may assess slightly different skills, so performance may not be identical across all tests.

Question 15

Anything that damages one mental ability also damages all other mental abilities.

Accepted Answer

It is possible for one mental ability to be damaged without affecting all other mental abilities. For example, a person may have a language impairment without having a negative impact on their mathematical abilities.

Question 16

The goal of the first intelligence tests was to identify the LEAST capable children,those who could not learn from ordinary schooling.

Accepted Answer

The first intelligence tests, developed by Alfred Binet in France, were designed to identify children who needed extra help in school, not to identify the least capable children. The aim was to identify children who might benefit from special education rather than to label them as incapable. However, over time, intelligence tests were sometimes used in ways that went beyond their original purpose, leading to controversy and criticism.

Question 17

​Scores on tests of language,logic,spatial reasoning,and other cognitive abilities all correlate positively with one another.

Accepted Answer

The statement is true based on research in intelligence testing and cognitive psychology. This positive correlation suggests that individuals who score high on one type of cognitive ability test are likely to also score high on other types of cognitive ability tests.

Question 18

Although the mean score on an IQ test is 100,the most common score is a few points higher.

Accepted Answer

This is true. The distribution of IQ scores follows a bell curve, with the majority of scores clustering around the mean of 100. However, due to the shape of the curve, slightly more individuals tend to score just above 100, making it the most common score.

Question 19

Researchers have identified three genes that control most of the individual differences in IQ scores.

Accepted Answer

There is no consensus among researchers that only three genes control most of the individual differences in IQ scores. IQ scores are influenced by a complex interplay between genetic and environmental factors.

Question 20

The results comparing monozygotic and dizygotic twins imply a genetic contribution to differences in IQ performance.

Accepted Answer

The comparison between monozygotic (identical) and dizygotic (fraternal) twins suggests that genetic factors play a role in individual differences in IQ performance. Monozygotic twins share all their genes, while dizygotic twins share only half, making it easier to separate the contributions of genetics from environmental factors. Studies have consistently found that the correlation in IQ scores between monozygotic twins is higher than between dizygotic twins, suggesting genetic influences. However, it is important to note that genetics is not the only factor contributing to IQ differences, and environmental factors also play a significant role.
