Chapter 8 Test

254

Test yourself repeatedly throughout your studies. This will not only help you figure out what you know and don’t know; the testing itself will help you learn and remember the information more effectively thanks to the testing effect.

Question 8.46

1. A mental grouping of similar things is called a _________.

concept

Question 8.47

2. The most systematic procedure for solving a problem is a(n) ___________.

algorithm

Question 8.48

3. Oscar describes his political beliefs as “strongly liberal,” but he has decided to explore opposing viewpoints. How might he be affected by confirmation bias and belief perseverance in this effort?

Oscar will need to guard against confirmation bias (searching for support for his own views and ignoring contradictory evidence) as he seeks out opposing viewpoints. Even if Oscar encounters new information that disproves his beliefs, belief perseverance may lead him to cling to these views anyway. It will take more compelling evidence to change his beliefs than it took to create them.

Question 8.49

4. A major obstacle to problem solving is fixation, which is a(n)

  1. tendency to base our judgments on vivid memories.

  2. tendency to wait for insight to occur.

reliability

255

Question 8.64

19. The strongest support for heredity’s influence on intelligence is the finding that

  1. identical twins, but not other siblings, have nearly identical intelligence test scores.

  2. the correlation between intelligence test scores of fraternal twins is not higher than that for other siblings.

  3. mental similarities between adopted siblings increase with age.

  4. children in impoverished families have similar intelligence scores.

a

Question 8.65

20. To say that the heritability of intelligence is about 50 percent means that 50 percent of

  1. an individual’s intelligence is due to genetic factors.

  2. the similarities between two groups of people are attributable to genes.

  3. the variation in intelligence within a group of people is attributable to genetic factors.

  4. intelligence is due half to the mother’s genes and half to the father’s genes.

c

Question 8.66

21. The environmental influence that has the clearest, most profound effect on intellectual development is

  1. exposing normal infants to enrichment programs before age 1.

  2. growing up in an economically disadvantaged home or neighborhood.

  4. being an identical twin.

c

Question 8.67

22. Use the concepts of crystallized and fluid intelligence to explain why writers tend to produce their most creative work later in life, while scientists often hit their peak much earlier.

Writers’ work relies more on crystallized intelligence, or accumulated knowledge, which increases with age. For top performance, scientists doing research may need more fluid intelligence (speedy and abstract reasoning), which tends to decrease with age.

Question 8.68

23. Which of the following is NOT a possible explanation for the fact that more intelligent people tend to live longer, healthier lives?

  1. Intelligence makes it easier to access more education, better jobs, and a healthier environment.

  2. Intelligence encourages a more health-promoting lifestyle.

  4. Prenatal events or early childhood illnesses could influence both intelligence and health.

c

Question 8.69

24. In prosperous country X everyone eats all they want. In country Y the rich are well fed, but the poor have very little to eat. In which country will the heritability of body weight be greater?
