The heritability of intelligence refers to A. The extent to which an individual's intelligence is attributable to genetic factors B. The percentage of variation in intelligence within a group that is attributable to genetic factors C. The extent to which a group's intelligence is attributable to genetic factors D. A general underlying intelligence factor that is measured by every task on an intelligence test E. The extent to which the environment plays a role in the intelligence of biologically related siblings

The similarity between the intelligence test scores of identical twins raised apart is A. Less than that between children and their biological parents B. Equal to that between identical twins reared together C. Equal to that between fraternal twins reared together D. Greater than that between ordinary siblings reared together E. Equal to that between adopted siblings reared together

J. McVicker Hunt began a program of tutored human enrichment in an Iranian orphanage. This program trained caregivers to A. Ignore babies' crying B. Imitate babies' babbling C. Assess babies' emotional intelligence D. Calculate babies' intelligence quotients E. Combat stereotype threat

The intelligence test scores of adopted children are LEAST likely to be positively correlated with the scores of their adopted siblings during A. Early childhood B. Middle childhood C. Early adolescence D. Middle adolescence E. Early adulthood

The importance of environmental influences on intelligence is provided by evidence that A. General intelligence scores predict performance on a variety of complex tasks B. The intellectual development of neglected children in impoverished environments is often depressed C. Identical twins reared together have similar intelligence scores than fraternal twins reared together D. Mental similarities between adopted children and their adoptive families increase with age E. The average IQ scores of children are generally within one standard deviation of their parents' IQ scores

Research on the determinants of intelligence indicated that A. Concern over the nature-nurture issue has declined significantly during the past 10 years B. Both genes and environment have some influence on intelligence scores C. There are no scientific methods for answering the nature-nurture question for a particular range of individuals or situations D. There is no relationship between people's position on the nature-nurture issue and their social and political attitudes E. Environmental influences outweigh any genetic influence there may be on intelligence levels

Interventions that promote intelligence teach early teens that the brain is like a muscle that strengthens with use. This idea is designed to encourage the teens to view intelligence as A. A reflection of the g factor B. A biologically determined capacity C. Changeable over time D. Distributed in a bell-shaped pattern E. An inborn trait with strengths and weaknesses

More positively; more negatively B. Less positively; less positively C. More negatively; less positively D. Less positively; more positively E. More positively; more positively

Research indicates that Head Start programs A. Contribute to dramatic and enduring gains in the participants' intelligence test scores B. Yield the greatest benefits for participants coming from intellectually stimulating home environments C. Reduce the likelihood that participants will repeat grades or require special education D. Generally are not cost effective in improving student achievement E. Improve analytically but not practical intelligence

The similarity between intelligence scores of fraternal twins reared together is A. Equal to that between identical twins reared apart B. Less than that between children and their biological parents C. Equal to that between ordinary siblings reared apart D. Less than that between identical twins reared apart E. Equal to that between adopted siblings reared together

Today's researchers have identified many different chromosomal regions important to intelligence. This indicates that intelligence is A. Related to neural plasticity B. Dependent on environmental factors C. A polygenetic trait D. Independent of neural processes E. Sensitive to stereotype threat
