After reading Fisher and Barak's article I was interested but confused on how one could write a research article using sexual explicit material as a variable. When I am conducting research for a paper or assigned to read a research paper one of the initial things I look at is what they are trying to prove or disprove and how they define their variables.
This is what confuses me about the Fisher and Barak article because how can you universally define sexually explicit material. I think an argument could be made that all definitions are relative and that my definition of "blue" may be different from another's definition. However, I think that this is a much greater cause for concern regarding the social issue of Internet pornography.
If I walked in my brother's room and saw a photo of a woman mostly naked in a lewd pose I would think he was just being a teenage guy. However, if someone else walked in they might think it was pornography. I believe that people have different tolerance levels and to create a universal tool that could measure the explicitness of sexual material.
Also many of the studies that Fisher and Barak used in their article included participants who were making decisions knowing that others would know their choices. I think that the fact "big brother" is watching would have an impact on how one would behave.
I understand that these issues of reliability and validity are not new ones, but I don't think that Fisher and Barak addressed them enough in order to establish credibility for the Sexual Behavior Sequence. Without have addressed these issues I don't think I can trust the results of the research without additional background information.
