Heritability relates to the

• percentage of a person’s intelligence that is due to environmental influences.

• percentage of a person’s intelligence that is due to genetics.

• correlation of intelligence test scores among family members.

• extent to which variability among individuals’ intelligence scores can be attributed to genetic variation.

• genetic stability of intelligence over time.

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?

• Nothing, because the type of twin has not been held constant.

• Nothing, because there is no comparison between twins and adopted children.

• Nothing, because cultural differences have not been considered.

• There is a genetic effect on intelligence.

• There is an environmental effect on intelligence.

Which of the following is true of the mental similarities between adoptive children and their adoptive parents as they age?

• Adoptive children become much more similar to their adoptive families over time.

• Adoptive children become slightly more similar to their adoptive families over time.

• There is hardly any similarity, either when the adoptive children are young or when they are older.

• Adoptive children become slightly less similar to their adoptive families over time.

According to Carol Dweck, students are often hampered by a “fixed mindset.” This means they believe:

• intelligence is biologically set and unchangeable.

• it is never good to change your mind once it is made up.

• intelligence can be “repaired” by doing specific mental exercises.

• they have already done everything they can to improve.

• problems can only be solved a particular way.
