Question 1

One effect of education on intelligence is evident in rapidly increasing IQ test scores around the world,a phenomenon called the Flynn effect.

Accepted Answer

The statement is true. The Flynn effect refers to the fact that IQ scores have been gradually increasing across the world over the last century, and this is attributed in part to improved education and other social factors.

Question 2

Heritability estimates suggest that more than 90 percent of the variation in height is explained by genetic variation.

Accepted Answer

Heritability estimates for height typically range between 60-80%, with some estimates being as high as 90%. This suggests that a large proportion of the variation in height can be attributed to genetic factors. However, it is important to note that heritability estimates are population-specific and can vary depending on environmental factors.

Question 3

Because heritability is a proportion,the highest degree of heritability is 100 percent.

Accepted Answer

Heritability is expressed as a proportion between 0 and 1, or as a percentage between 0% and 100%. Therefore, the highest degree of heritability is 100%.

Question 4

Organic intellectual disability is caused by a genetic disorder or brain damage.

Accepted Answer

Organic intellectual disability is caused by a physical or biological problem such as genetic disorders, brain damage, or prenatal exposure to alcohol or drugs.

Question 5

Coping with stressful situations is a form of problem solving.

Accepted Answer

Coping with stressful situations involves recognizing and addressing the sources of stress, developing strategies for managing emotions and thoughts, and taking action to reduce the impact of stress on one's physical and mental health. This is a form of problem solving, as it requires identifying and working to solve a problem or challenge.

Quiz 8: Thinking, Intelligence, and Language

One effect of education on intelligence is evident in rapidly increasing IQ test scores around the world,a phenomenon called the Flynn effect.

Heritability estimates suggest that more than 90 percent of the variation in height is explained by genetic variation.

Because heritability is a proportion,the highest degree of heritability is 100 percent.

Organic intellectual disability is caused by a genetic disorder or brain damage.

Coping with stressful situations is a form of problem solving.
