Lab Members Arnold Ho: Arnold's research focuses on stereotype threat, Black exceptionalism, and social dominance theory. He is interested in identifying factors that moderate and mediate the stereotype threat effect. With respect to Black exceptionalism, he is exploring the notion that African Americans are unique in facing an impenetrable color line. Finally, Arnold is investigating gender differences in social dominance orientation and differences in ingroup bias across groups. Arnold holds a B.A. in Psychology from the University of California, Davis and a M.A. in Psychology from the University of California, Los Angeles (UCLA). Lotte Thomsen: Coming soon.
