Question 1

Today's IQ scores are based on a person's performance relative to the scores of other people of the same age,with a score of _____ corresponding to the average performance of that age group.

Accepted Answer

A score of 100 corresponds to the average performance of the person's age group.

Question 2

Early intelligence researcher Francis Galton believed that certain people were occupationally and socially successful as a result of:

Accepted Answer

Galton believed that success was largely determined by one's biological makeup, specifically the efficiency of their nervous system.

Question 3

Stern's intelligence quotient was determined by dividing __________ by _______,multiplied by 100.

Accepted Answer

Stern's intelligence quotient was determined by dividing his mental age by his chronological age, then multiplying by 100. This was the original formula for calculating IQ, developed by William Stern in the early 20th century.

Question 4

The concept of "mental age" is most strongly associated with which of the following individuals?

Accepted Answer

The concept of "mental age" was first introduced by Alfred Binet in his development of the first intelligence test in the early 1900s. The concept refers to the level of intellectual functioning typically found at a certain age, regardless of chronological age.

Question 5

According to the text,the following term is defined as the individual differences in the ability to acquire knowledge,to think and to reason effectively,and to deal adaptively with the environment:

Accepted Answer

Intelligence is defined as the individual differences in the ability to acquire knowledge, to think and to reason effectively, and to deal adaptively with the environment.

Question 6

Which of the following individuals first adapted Alfred Binet's intelligence test for using with American children?

Accepted Answer

Lewis Terman adapted Alfred Binet's intelligence test for use with American children and published the Stanford-Binet Intelligence Scale in 1916.

Question 7

A child with a mental age of 10 and a chronological age of 8 would have an IQ of ___,according to Stern.

Accepted Answer

According to Stern's formula, IQ is calculated as (MA/CA) x 100. Therefore, in this case, the IQ would be (10/8) x 100 = 125.

Question 8

According to Stern's measure,an 8-year-old boy with a mental age of 4 would have an IQ of:

Accepted Answer

Using Stern's measure, the formula for calculating IQ is (mental age/chronological age) x 100.

In this case, the mental age is 4 and the chronological age is 8, so the formula would be (4/8) x 100 = 50. Therefore, the correct answer is C) 50.

Question 9

Who among the following men made the two assumptions in his work on intelligence that: mental abilities develop with age,and that the rate of developmental change is relatively constant for a given individual?

Accepted Answer

The two assumptions mentioned are central to Alfred Binet's work on intelligence, specifically his development of the first intelligence test. Sir Francis Galton was more focused on the idea of inherited intelligence, while Lewis Terman and William Stern built off of Binet's work but did not necessarily make these assumptions in their own research.

Question 10

According to Sir Francis Galton,which of the following was NOT related to intelligence?

Accepted Answer

Sir Francis Galton believed that intelligence was largely inherited and associated with physiological factors such as reaction speed and skull size. He did not believe that a privileged environment could significantly influence intelligence.

Question 11

Who among the following early intelligence researchers observed how intelligence appeared to run in certain families and contended that this factor must therefore be largely determined by genetic or biological factors? However,a major shortcoming of this conclusion was that he failed to take the impact of the environment into account.

Accepted Answer

Sir Francis Galton observed how intelligence appeared to run in certain families and contended that this factor must therefore be largely determined by genetic or biological factors. However, he failed to take the impact of the environment into account, which is now recognized as a major shortcoming of his work.

Question 12

Stern's intelligence quotient was calculated as a(n):

Accepted Answer

Stern's intelligence quotient formula was mental age divided by chronological age multiplied by 100. This is a ratio of mental age to chronological age.

Question 13

The first use of the term "intelligence quotient" or IQ is generally attributed to:

Accepted Answer

William Stern, a German psychologist, is credited with coining the term "Intelligence Quotient" or IQ. He introduced this as a way to score early intelligence tests, specifically to calculate a ratio of mental age to chronological age.

Question 14

Historically,setting the stage for later attempts to measure intelligence and discover its causes was the result of the contributions of __________________ and _______________.

Accepted Answer

Francis Galton and Alfred Binet were the two individuals who made significant contributions to the measurement and understanding of intelligence. Galton developed the concept of hereditary genius and attempted to measure intelligence through physical and sensory tests. Binet developed the first standardized intelligence test, which was designed to identify children who needed extra educational support. Their work laid the foundation for later attempts to measure intelligence and understand its causes.

Question 15

Alfred Binet would be most likely to endorse which of the following statements about intelligence?

Accepted Answer

Alfred Binet, known for developing the first practical IQ test, believed that intelligence was not fixed and could improve over time. He introduced the concept of mental age, suggesting that the rate at which a person gains knowledge is an internal characteristic that can vary but remains relatively constant for the individual, emphasizing the potential for personal growth and development in intelligence.

Question 16

According to Binet's concept of mental age,if an 8-year-old child could solve problems at the level of the average 10-year-old,the child would be said to have a mental age of:

Accepted Answer

According to Binet's concept of mental age, the child's mental age is determined based on their level of problem-solving ability. If an 8-year-old child can solve problems at the level of an average 10-year-old, then their mental age is considered to be 10. Therefore, the best choice is C) 10.

Question 17

Who among the following was commissioned by France's Ministry of Public Education to develop the test that was to become the forerunner of all modern intelligence tests?

Accepted Answer

Alfred Binet was commissioned by France's Ministry of Public Education to develop the test that was to become the forerunner of all modern intelligence tests. Galton, Terman, and Wechsler made significant contributions to the field of psychology and intelligence testing, but they were not directly involved in the creation of this particular test.

Question 18

By the age 4,based on the Stanford-Binet Intelligence test,a child should be able to:

Accepted Answer

By age 4, a child should be able to define words such as ball and bat, according to the Stanford-Binet Intelligence test. The other options, counting up to nine blocks and repeating four digits in reverse order, are skills expected of younger children. Defining more complex words such as muzzle would be expected of older children.

Question 19

According to the text,intelligence is best described as a:

Accepted Answer

The text states that intelligence is a socially constructed concept that can mean different things to different people, indicating that it is not easily measurable or universally agreed upon. It also notes that some cultures may have different perspectives on what constitutes intelligence. Therefore, options A, B, and D are not accurate descriptions of intelligence as presented in the text.

Question 20

Alfred Binet became interested in the intelligence testing as a result of his position in the French _________.

Accepted Answer

Alfred Binet was appointed in 1904 by the French Ministry of Education to head a commission that developed a method for identifying schoolchildren who needed special help. This led to the creation of the first intelligence test.
