According to the discussion of visual imagery during problem solving,
a. visual images can be nontraditional, so they are sometimes more helpful than symbols and other methods of representing a problem.
b. surprisingly, people who are high in visual-imagery abilities are no more likely than other people to use imagery effectively during problem solving.
c. visual imagery is helpful only if problem solvers are initially instructed to visualize a familiar object.
d. a disadvantage to visual imagery is that it can only be used if you have a clear idea about the solution to the problem.
Question 2
According to the research on the use of diagrams in problem solving,
a. diagrams are often helpful because they can convey information in a clear way.
b. a hierarchical tree diagram is a list of steps that must be followed in solving a problem.
c. the most effective way to use diagrams is to construct a matrix representing all possible combinations of options.
d. people seldom solve problems by using diagrams, because verbal representations are much more appealing.
