Exam 9: Constructivist Learning Theory, Problem Solving, and Transfer

When graphing the results of factorial experiments, you should put ____ on the y-axis.

In a 2 X 3 X 2 between-subjects design, there are ____ independent variables.

Attributing causality to a subject variable is incorrect because:

Contrast a between-subjects design and a within-subjects design.

Relatively permanent participant characteristics that prevent random assignments are called:

A professor was interested in whether caffeine affected test performance. To test this possibility, he gave students a test and asked them whether they had consumed caffeine in the hour before the test. He then compared the performance of those students who had taken caffeine to those who had not. Why is this not a true experiment?

Refer to Scenario 9-1. Diagram this experimental design and describe it in words.

In a study on the effects of smoking deprivation on memory recall, participants, who all smoked, were randomly assigned to one of four groups: not deprived of smoking, deprived for 4 hours, deprived for 8 hours, deprived for 12 hours. Subjects were then tested for their recall of nonsense syllables learned one hour before. Diagram the design and describe it in words.

The study by Bransford and Johnson is described in the chapter as having a:

Refer to Scenario 9-1. Suppose the experimenter now wanted to know whether the results of the above study would be the same for men and women. How would you describe this new design? What problems in interpretation might arise?

If there is an interaction in a factorial experiment,:

What is an interaction effect and how is it represented graphically?

In a 2 x 2 experiment, if you portray the results by using a line graph, an interaction is indicated by:

In a 2 X 2 factorial design there are:

In a 2 X 3 design, the number of null hypotheses that must be evaluated is:

The type of experimental design that allows us to examine the effects of more than one independent variable both individually and collectively is called:

In between-subjects designs:

Describe an experimental scenario where finding an interaction can be very important.

If you wanted to examine the difference between students who were exposed to a lab in research methods versus those who were not, and those involved in empirical research versus those who were not, you would use a ____.

In an analysis of variance summary table, MS stands for:
