Respond to the following points

1. First, briefly describe the steps you took to locate this article. (know that you can say anything including 'a friend sent it to me'; I actually just want to learn how you are getting these articles!)

2. The researchers use a bit of folk wisdom to justify their research programme, what is the common expression associated with this folk wisdom? Do you think this is a good or bad justification for research? Why?

3. State the researcher's hypotheses for this line of research . (Note that each IV~DV relationship should have its own hypothesis)

4. State the operational definition of the independent variable(s) including each level of the IV(s), please be specific:

5. State at least three controls that the researchers used to ensure that the photographs of people in the two conditions were similar to each other. For each of the controls please explain (tell a story) about why it was important for the experimenter to assert control over the variable.
