 What evidence did Spearman have for the existence of g?

• Scores of monozygotic twins correlate highly with each other

• Scores on any test of intelligent performance correlate positively with scores on other tests

• Children who are identified as intellectually gifted tend to become highly productive adults

• On the average, intelligence scores are equal for males and females

On average, how does intelligence change from young adulthood to old adulthood?

 

• Both fluid and crystallized intelligence decline

• Fluid intelligence declines, but crystallized intelligence remains constant or increases

• Fluid intelligence remains constant or increases, but crystallized intelligence declines

• Both fluid and crystallized intelligence remain constant or increase

What evidence would demonstrate the existence of an intellectual ability separate from g?

 

• People with this ability do well on all measures of intelligent behaviour

• People with this ability do not do well in school

• The ability predicts some type of intelligent behaviour but has a low correlation with the tests that measure g

What was the original purpose of Binet’s first IQ test?

 

• To select the brightest students for advanced training

• To compare the performance of ethnic groups

• To determine the relationship between intelligence and brain size

• To identify slow learners who needed special education

What is the concept of 's' in the context of intelligence?

• It represents specific abilities related to a particular task or domain

• It is a measure of general intelligence

• It refers to the ability to adapt to new situations and solve problems

• It is a measure of emotional intelligence

At what age does fluid intelligence typically peak?

• During childhood

• In 20s

• In late 60s

• Late 40s

Under what circumstances do environmental interventions most strongly promote intellectual development?

• If they start in early childhood

• If they take place during school hours

• If they start during adolescence

• If large numbers of children are taught together at the same time

Theoretically, the distribution of IQ scores should have a mean of 100 and an equal number of people above and below the mean. How does the actual distribution of scores differ from this prediction?

• The actual mean is 105

• The actual mean is 95

• The mode (most common score) is 105

• The mode (most common score) is 95

On average, how do males and females compare in IQ?

• On average, males have a higher IQ

• On average, females have a higher IQ

• On average, males and females are equal on all subtests and on average IQ

• On average, males and females differ on certain sub scores, but are equal on overall IQ

Why have psychologists needed to re-standardize IQ tests repeatedly over the years?

• To prevent the mean from increasing above 100

• To prevent the mean from decreasing below 100

• To match the changes in school curricula

• To measure newly evolved abilities
