Target of replication. We are attempting to replication Study 2. Low-prejudice people vary considerably in their ability to regulate intergroup responses. In the original study, the authors hypothesized that this variability arises from a neural mechanism for monitoring conflict between automatic race-biased tendencies and egalitarian intentions. They found that low-prejudice participants whose nonprejudiced responses were motivated by internal (but not external) factors exhibited better control on a stereotype-inhibition task than did participants motivated by a combination of internal and external factors, and that these group differences were specific to response control in the domain of prejudice.
A priori replication criteria. Using a 2 (Group: high IMS/low EMS vs. high IMS/high EMS) 2 (Task: weapons vs. flankers) ANOVA on PD-control estimates, the original study found a significant interaction, F(1, 31) = 5.14, p = .03. A successful replication would observe a similarly positive and significant F statistic.
