... Skill level has not been ignored in the stereotype threat literature and is frequently operationalized by a measure of previous performance in the domain. Instead of modeling skill level as a moderator variable, studies have typically controlled for skill level in order to test whether the effect of stereotype threat is statistically significant beyond that of skill level or to increase the power to detect the effects of stereotype threat on performance (Steele & Aronson, 2004). Many studies examining the effect of the stereotype about women's math abilities have sampled those with relatively high SAT math scores (e.g., Martens, Johns, Greenberg, & Schimel, 2006;Marx & Roman, 2002;Quinn & Spencer, 2001;Schmader, 2002;Schmader & Johns, 2003;Shih, Pittinsky, & Ambady, 1999;Spencer et al., 1999) or have controlled for SAT math scores for these reasons (e.g., Gonzales, Blanton, & Williams, 2002;Hollis-Sawyer & Sawyer, 2008;Inzlicht & Ben-Zeev, 2000Keller, TESTING HYPOTHESIZED MODERATORS OF STEREOTYPE THREAT 2002, 2007Lesko & Corpus, 2006;Marx & Roman, 2002;Schmader, 2002;Schmader & Johns, 2003;Steele & Aronson, 1995;Vick, Seery, Blascovich, & Weisbuch, 2008;Wout, Danso, Jackson, & Spencer, 2008;Wout, Shih, Jackson, & Sellers, 2009). ...
