Modules 63 and 64 Reading Quiz

The extent to which intelligence test score variation can be attributed to genetic variation is called

• heritability.

• being as smart as your mom.

• inherited traits.

• nurture.

• environmental influence.

According to Myers, estimates of the heritability of intelligence range from

• 10 - 50 percent.

• 20 - 60 percent.

• 30 - 70 percent.

• 50 - 80 percent.

• 70 - 100 percent.

Where environments vary widely, environmental differences are

• more predictive of intelligence scores.

• less predictive of intelligence scores.

• not at all predictive of intelligence scores.

Over the lifetime of a person, genetic influences of intelligence seem to matter

• less. In other words, as a person ages, they are less like their biological parents and intelligence seems to be more influenced by the environment.

• the same. In other words, as a person ages, they are pretty stable in term of intelligence.

• more. In other words, as a person ages, they are more like their biological parents and intelligence seems to be less influenced by the environment.

The "growth mindset" teaches people that the brain is

• fixed; you either have it or you don't.

• like a muscle that grows with exercise.

• unstoppable if you just try.

• like a muscle, ready for growth, for those people who have an IQ within one standard deviation of normal.

• like a muscle, ready for growth, for those people who have an IQ at 100 or above.

The correlation between the IQ scores of fraternal twins raised together is lower than IQ scores of identical twins raised together. What conclusion can be drawn from this data?

• There can be no conclusion, because the type of twin has not been held constant.

• There can be no conclusion, because there is no comparison between twins and adopted children.

• There can be no conclusion, because cultural differences have not been considered.

• There is a genetic effect on intelligence.

• There is an environmental effect on intelligence.

The self-confirming concern that one will be evaluated based on a negative stereotype is called

• racism.

• sexism.

• confirmation bias.

• availability heuristic.

• stereotype threat.

According to most experts, intelligence tests are not biased because

• the average scores for various racial and ethnic groups do not differ by much.

• the tests do a pretty good job of predicting what they are supposed to predict.

• cultural background has little influence on test scores.

• the scores on the test are not very stable even when you don't consider race.
