“…Researchers have posited a number of potential explanations for gender differences in mathematics performance and for the underrepresentation of women in mathematics-and science-related careers, including biological factors (e.g., Benbow & Stanley, 1980;Geary, 1996;Scarr & Carter-Saltzman, 1982), social factors (e.g., Eccles, 1987;Eccles & Jacobs, 1986;Heller & Ziegler, 1996), and the interaction between biological and social factors (e.g., Halpern & Tan, 2001;Nuttall, Casey, & Pezaris, 2005). One of the key social factors that has been suggested as contributing to highachieving women's underperformance on mathematics tests is stereotype threat (Steele, 1997;Steele & Aronson, 1995).…”
