Empirical Methods in Communication
Briefly answer five essay questions that require you to dissect an experiment by Palomares and Lee, that was published in a 2010 issues of the Journal of Language and Social Psychology. Your answers must be typed and double spaced. Provide a 1½ inch margin on all sides of the page for written comments. Your paper must absolutely not be longer than 1000 words; that is about 200 words per question. All word processors have a word count feature. Please provide the word count of your essay (excluding your name and other identifying information).
1. Palomares and Lee used a 2x2x2 between-subjects factorial design. (This kind of design
is referred to as “between-subjects” because each research participant was assigned to
only one experimental condition.) Explain why this design was necessitated by the
2. Experimental control is a critical feature of any experiment. If we wish to know the effects
of independent variables on dependent variables we must “hold constant” other variables
that would make causal inference challenging. What efforts were taken in this experiment
to achieve a high level of experimental control?
3. What efforts were made to determine if the manipulations of the independent variables
4. Did this experiment measure any potential mediating variables? If so, what were these
variables? If no, why not?
5. The generalizeability of every experiment has limitations, and this study is no exception.
Briefly describe how our ability to generalize from the findings obtained are limited.
Your answers to these five questions will be equally weighted. Evaluation is based on the
thoughtfulness of your response and the quality of your writing..
