Lesson 13 and 14 Practice Quiz

1. What advantage is there to using a heuristic rather than an algorithm?

a. A heuristic is often more efficient

b. A heuristic will present a more clearly defined solution

c. A heuristic will result in only one possible solution

d. A heuristic is more likely to result in a correct response

2. Suppose we measure characteristics in siblings reared together and find a 0.11 correlation for

adopted siblings who are biologically unrelated, compared with a 0.56 correlation for fraternal

twins, and a 0.93 correlation for identical twins. This suggests that:

a. Have lower levels of activation in areas of the brain used to perform a task

b. Use fewer areas of their brains when solving complex problems

c. Conserve energy (lower glucose metabolism as problems become increasingly more complex

d. All of the above

4. Intelligence is determined, in descending order, by:

a. Shared environment; genes; unique environment

b. Genes; unique environment; shared environment

c. Shared environment; unique environment; genes

d. Genes; shared environment; unique environment

5. Wechsler’s IQ test differed from its predecessors in that it:

result of genetic difference. How accurate is Janice’s assumption?

a. She’s correct in her reasoning, but only in principle; estimates of IQ heritability vary widely,

depending on the method used to produce them (E.g., twin studies, adoptive studies, etc.), and

thus they cannot serve to generalize to between-group differences

b. She’s incorrect; the heritability of a trait within a group tells us nothing about observed

differences in that trait between groups

c. She’s correct; heritability coefficients for a trait within a group are usually quite similar to the

heritability of that trait between groups

d. She’s incorrect; high heritability of a trait within a group directly implies high environmentally

for that trait between groups
