Question 1

In order to be useful a test must have either high validity or high reliability.

Accepted Answer

A test needs to have both high validity and high reliability to be truly useful; validity ensures the test measures what it is supposed to measure, and reliability ensures it produces consistent results over time.

Question 2

All that must be true for an individual to be classified as intellectually disabled is that that individual's IQ be below 70.

Accepted Answer

Intellectual disability is a complex condition and IQ is just one of the factors used to assess it. Other factors such as adaptive functioning and age of onset also need to be taken into consideration before classifying an individual as intellectually disabled. Therefore, having an IQ below 70 alone does not necessarily mean an individual is intellectually disabled.

Question 3

The primary method of study employed by behavioural geneticists is currently DNA testing.

Accepted Answer

Behavioral geneticists primarily use twin studies, family studies, and adoption studies to understand the influence of genetics and environment on behavior. DNA testing is a tool, but not the primary method of study.

Question 4

Most studies indicate that IQ test scores are fixed and can't be significantly modified by the environment.

Accepted Answer

While IQ test scores have some degree of stability over time, they can be influenced by environmental factors such as education, nutrition, and exposure to different experiences. In fact, research has shown that environmental interventions can lead to improvements in IQ scores, particularly in children.

Question 5

The Wechsler Adult Intelligence Scale was the first to provide a scale for adults.

Accepted Answer

The Wechsler Adult Intelligence Scale (WAIS) was developed by David Wechsler in 1955 and was the first intelligence test specifically designed for adults. It provides a scale of intelligence for individuals aged 16 to 90 years old.

Question 6

Acceleration programs and enrichment programs are different terms for the same thing.

Accepted Answer

Acceleration programs focus on allowing students to progress through their academic studies at a faster pace, while enrichment programs focus on providing additional opportunities and experiences for students to enhance their learning beyond the regular classroom curriculum. While there may be some overlap between the two, they are generally considered to be distinct types of programs.

Question 7

The Wechsler Adult Intelligence Scale contains both verbal and intuitive sub­tests, which yield separate verbal and intuitive IQ scores as well as an overall IQ score.

Accepted Answer

The Wechsler Adult Intelligence Scale contains both verbal and performance (not intuitive) subtests, which yield separate verbal and performance IQ scores as well as an overall IQ score.

Question 8

The Stanford-Binet Intelligence Scale can be administered individually or to groups.

Accepted Answer

The Stanford-Binet Intelligence Scale is designed to be administered on an individual basis, not to groups.

Question 9

Contextual intelligence is similar to "street smarts."

Accepted Answer

Contextual intelligence requires understanding and adapting to different social and cultural environments, much like "street smarts" involve being knowledgeable and savvy about navigating difficult or unfamiliar situations in real-world settings.

Question 10

The first intelligence tests developed by Alfred Binet were intended to identify children whose mental ability was too limited for them to profit from regular classroom instruction.

Accepted Answer

This is a true statement. Alfred Binet developed the first intelligence tests in France in the early 1900s, specifically to identify children who were struggling in school due to limited mental ability. The tests were meant to identify these children early on so they could receive special education and support.

Question 11

Crystallized intelligence refers to abstract reasoning and mental flexibility.

Accepted Answer

Crystallized intelligence refers to the knowledge and skills that one has accumulated over time, including vocabulary and factual information, which is different from abstract reasoning and mental flexibility, which are aspects of fluid intelligence.

Question 12

Around 4 to 6 percent of the Canadian population have IQ scores that place them in the range of an intellectual disability.

Accepted Answer

Intellectual disability affects approximately 1% of the population, not 4 to 6 percent. The majority of IQ scores are within the average range, and a smaller percentage falls into the categories of intellectual disability or giftedness.

Question 13

A reliable test is one that has carefully established norms of performance.

Accepted Answer

A reliable test is one that yields consistent results over time, not necessarily one with established norms of performance, which relates more to validity and standardization.

Question 14

In his study of geniuses, Lewis Terman found that the mentally superior were often close to being insane.

Accepted Answer

Lewis Terman's study actually found no evidence of a correlation between high intelligence and any type of mental illness. In fact, he found that the geniuses he studied had lower rates of mental illness than the general population.

Question 15

In his study of geniuses, Lewis Terman assumed that intelligence was fixed at birth.

Accepted Answer

Lewis Terman believed in the concept of innate, fixed intelligence and assumed that geniuses were born with high intelligence levels.

Question 16

IQ stands for "intelligence quota."

Accepted Answer

IQ actually stands for "intelligence quotient."

Question 17

Adoption studies reveal that children adopted shortly after birth have IQs closer to their biological than to their adoptive parents' IQs.

Accepted Answer

Adoption studies have consistently found that biological relatives' IQs tend to have a greater correlation with the adopted child's IQ than the IQs of their adoptive relatives. This suggests that genetic factors play a larger role in determining IQ than environmental factors such as upbringing and education.

Question 18

The average IQ score for all people in all age ranges is arbitrarily set at 100.

Accepted Answer

This is a commonly accepted convention in IQ testing, where the average score is always set at 100 and the standard deviation is always set at 15.

Question 19

Crystallized intelligence refers to verbal ability and accumulated knowledge.

Accepted Answer

Crystallized intelligence involves the ability to use accumulated knowledge and verbal skills. It is also known as acquired intelligence.

Question 20

The Stanford-Binet Intelligence Scale used the norms established for French children when the test was given to American children.

Accepted Answer

The Stanford-Binet Intelligence Scale was adapted by Lewis Terman at Stanford University from the Binet-Simon scale, originally developed in France. Terman revised the test for use in the United States, including establishing new norms based on American children, not French children.
