Question 1

When the Stanford-Binet was first used, the intelligence quotient could be determined by the
A) mental age being divided by the chronological age and then multiplied by 100.
B) chronological age being divided by the mental age and then multiplied by 100.
C) mental age being multiplied by the chronological age and then divided by 100.
D) chronological age being divided by 100 and then multiplied by the mental age.

Accepted Answer

The original formula for calculating the intelligence quotient (IQ) in the Stanford-Binet test involves dividing the mental age (MA) by the chronological age (CA) and then multiplying the result by 100. This formula was designed to quantify intellectual development relative to an individual's age.

Question 2

If you score at the 50S1U1P1thS1S1P0 percentile on an intelligence test, this means that
A) you correctly answered half of the questions on the test.
B) you scored significantly below average on this test.
C) fifty people who took the test scored lower than you.
D) half the people your age who took the test scored higher than you and half scored lower than you.

Accepted Answer

Scoring at the 50th percentile on an intelligence test means that you scored higher than or equal to 50% of the people your age who took the test, and lower than or equal to the other 50%. It's a measure of relative performance, not the number of questions answered correctly or the number of people who scored lower.

Question 3

When one's mental age is the same as one's actual age in years, then
A) the test lacks reliability.
B) one's IQ is over 100.
C) one's IQ is below 100.
D) one's IQ is 100.

Accepted Answer

An IQ score of 100 indicates that one's mental age matches their actual age, so if one's mental age is the same as their actual age in years, then their IQ is 100.

Question 4

The subtests of Digit Span and Arithmetic make up which section of the Wechsler Adult Intelligence Scale (WAIS-IV)?
A) verbal comprehension
B) perceptual reasoning
C) working memory
D) processing speed

Accepted Answer

Digit Span and Arithmetic are both subtests that assess working memory, which is a component of the working memory section of the WAIS-IV.

Question 5

Grades and school success tend to be influenced by
A) IQ scores.
B) motivation.
C) off-campus educational opportunities.
D) all of these.

Accepted Answer

While IQ scores can play a role in academic success, motivation and off-campus educational opportunities also have a significant impact. Students who are motivated to learn and have access to resources outside of the traditional classroom setting are more likely to perform well in school. Therefore, the best answer is D as all three factors (IQ, motivation, off-campus opportunities) can influence grades and success in school.

Question 6

The fact that 14 nations have shown average IQ gains of from five to 25 points during the last 30 years is referred to as the __________ effect.

Question 7

One explanation for the extraordinary performances of people with savant syndrome is that an area of the brain is damaged, freeing the person from the "distractions" of language, concepts, and higher-level thoughts. This area of the brain that is theorized to be damaged in persons with savant syndrome is the __________.

Accepted Answer

The answer of One explanation for the extraordinary performances of...

Question 8

Regarding the identification of giftedness, which of the following statements is FALSE?
A) Limiting giftedness to high IQ can shortchange children with special talents.
B) Ethnic minority children may not be recognized as gifted because of subtle biases in standardized intelligence tests.
C) Children with physical disabilities are more likely to be recognized as being gifted because of the contrast with their physical abilities.
D) Early signs of giftedness include showing kindness, understanding, and cooperation with others.

Accepted Answer

Children with physical disabilities are not more likely to be recognized as being gifted because of the contrast with their physical abilities. In fact, they may be overlooked for giftedness because of the focus on their disabilities rather than their potential abilities. The other statements are true; high IQ alone does not fully capture the range of giftedness, biases in testing can lead to underidentification of giftedness in minority children, and early signs of giftedness can include social and emotional traits such as kindness and cooperation.

Question 9

Suzy is taking the Stanford-Binet (SB5) and is asked this question, "I knew my bag was going to be in the last place I looked, so I looked there first. What is silly or impossible about that?" This question is measuring Suzy's
A) fluid reasoning.
B) working memory.
C) quantitative reasoning.
D) visual-spatial processing.

Accepted Answer

This question is asking Suzy to recognize a logical fallacy, which requires the use of fluid reasoning, the ability to solve problems in new situations without relying on previously learned information or strategies. Working memory, quantitative reasoning, and visual-spatial processing are not directly involved in answering this question.

Question 10

When members of the Kpelle tribe in Liberia were asked to sort objects "like a fool would do it," they grouped them together
A) haphazardly and randomly.
B) by category, such as containers, clothing, and eating utensils, as done in Western cultures.
C) by functional association, such as food being placed with the utensil used to eat it.
D) like their own culture sorts objects.

Accepted Answer

The answer of When members of the Kpelle tribe in...

Question 11

According to your textbook, those who are labeled as having an intellectual disability
A) must have an IQ above 70 but below 100.
B) are sensitive to rejection and easily hurt by teasing and ridicule.
C) cannot become well-adjusted members of society.
D) also have savant syndrome.

Accepted Answer

Individuals with intellectual disabilities often experience heightened sensitivity to social cues such as rejection, teasing, and ridicule. This sensitivity can affect their social interactions and emotional well-being. The other options are incorrect: A) The IQ threshold for intellectual disability is typically below 70, not within the 70-100 range. C) Many individuals with intellectual disabilities can become well-adjusted members of society with appropriate support and interventions. D) Savant syndrome is rare and not a characteristic of all individuals with intellectual disabilities; it involves exceptional abilities in a specific area despite significant cognitive challenges.

Question 12

The five to 25-point IQ gains that have occurred in 14 nations in the last 30 years reflect the influence of all of the following EXCEPT
A) genetics.
B) improved education.
C) improved nutrition.
D) living in a technologically complex society.

Accepted Answer

The gains in IQ observed across various nations over the last 30 years are largely attributed to environmental factors such as improved education, nutrition, and the complexity of living in a technologically advanced society, rather than genetics, which does not change significantly within such a short timeframe.

Question 13

Because identical twins separated at birth did have the same prenatal environment and are often placed in homes that are socially and educationally similar, some researchers believe that intelligence would seem to
A) be 80 percent hereditary.
B) be 65 percent hereditary.
C) be less than 50 percent hereditary.
D) have no hereditary basis.

Accepted Answer

The answer of Because identical twins separated at birth did...

Question 16

Regarding group intelligence tests, which of the following statements is FALSE?
A) Group intelligence tests can be given to a large group of people with minimal supervision.
B) Group intelligence tests usually require people to read and follow instructions.
C) Group intelligence tests require people to solve problems of logic, reasoning, mathematics, or spatial skills.
D) The Wechsler Adult Intelligence Test and the Stanford-Binet are two examples of group intelligence tests.

Accepted Answer

The Wechsler Adult Intelligence Test and the Stanford-Binet are examples of individual intelligence tests, not group intelligence tests. These tests are administered on a one-on-one basis, not to large groups.

Question 17

In Terman's study, the main difference between the most successful gifted and the least successful gifted students was that the successful ones had the desire to know, to excel, and to persevere, which is known as intellectual __________.

Accepted Answer

The answer of In Terman's study, the main difference between...

Question 18

Regarding genetic factors linked to intellectual disabilities, which of the following statements is FALSE?
A) Although Down syndrome is genetic, it is not usually hereditary in the sense that it doesn't "run in the family."
B) Down syndrome children have an extra X chromosome in the 23rd pair.
C) Children with PKU (phenylketonuria) have an inherited inability to control a destructive chemical that builds up in their bodies.
D) Individuals with Down syndrome have almond-shaped eyes, a slightly protruding tongue, a stocky build, and stubby hands with deeply creased palms.

Accepted Answer

Down syndrome is caused by an extra copy of chromosome 21, not an extra X chromosome. This condition is also known as trisomy 21.

Question 19

The majority of the gifted in Terman's study f inished college, earned advanced degrees, or held professional positions.

Accepted Answer

Terman's longitudinal study, which began in the early 20th century, followed a group of gifted children throughout their lives and found that the majority did indeed achieve high levels of education and professional success, including finishing college, earning advanced degrees, and holding professional positions.

Question 20

Persons scoring above 130 on IQ tests
A) will usually "fizzle out" as adults.
B) are called "gifted."
C) make up less than one-half of one percent of the population.
D) will be more likely to be emotionally disturbed or unemployed.

Accepted Answer

Individuals scoring above 130 on IQ tests are generally considered to be in the "gifted" range. This is a term commonly used to describe individuals with exceptional intellectual ability. The other answer choices are not accurate or supported by research.
