You conducted a laboratory experiment investigating the effects of a perspective

You conducted a laboratory experiment investigating the effects of a perspective taking intervention on participants’ attitudes toward outgroup members (e.g., if participants were Democrats, outgroup members would be Republicans). You created a new measure of prejudice because you did not like the established scales. Your results indicated that at Time 1, prejudice scores were similar for the treatment and control groups; however, at Time 2, prejudice scores were slightly, but significantly, lower in the control group. How could that be? Could there be something wrong with the way you measured prejudice? How might your knowledge of measurement validity explain these results? What other possibilities can you generate? Discuss the different aspects of measurement validity and how they could have affected your results.
