Stereotype lift occurs when non-targets perform better in a stereotype-relevant testing situation compared to a testing situation that is less stereotype-relevant. The boundary conditions of this effect, however, are not well understood. To this end, the present research focuses on one critical moderator of stereotype lift, namely activation of non-targets' social self in stereotype-relevant (i.e., diagnostic) testing situations. Results showed that simply describing a test as diagnostic of ability did not lead to strong lift effects unless the social self was also activated (either indirectly or directly): non-targets need more "pushing" to activate their social self in diagnostic testing situations because they are not threatened by a negative stereotype. In contrast, we found that the test diagnosticity manipulation was enough to cause stereotype threat because targets need less pushing to activate their social self and the associated negative stereotype in diagnostic testing situations.Considerable research has focused on the adverse effects of negative stereotypes on targets' test performance in stereotype-relevant situations (i.e., stereotype threat; Steele, 1997;Steele & Aronson, 1995). In contrast, far less work has focused on the test performance boost of non-targets in those same settings, for example, when male partici-776
