The Affect Misattribution Procedure.

The Affect Misattribution Procedure (AMP) has been forwarded as one of the most promising alternatives to the Implicit Association Test and the evaluative-priming task for measuring attitudes such as prejudice indirectly. We investigated whether the AMP is indeed able to detect an evaluative out-group bias. In contrast to recent conclusions about the robustness of AMP effects, six out of seven pilot studies indicated that participants did not show any prejudice effects in the AMP. Yet, these pilot studies were not fully conclusive with regard to our research question because they investigated different domains of prejudice, used small sample sizes, and employed a modified AMP version. In a preregistered, high-powered AMP study, we therefore examined whether the standard AMP does reveal prejudice against Turks, the biggest minority in Germany, and found a significant, albeit very small prejudice effect. We discuss possible reasons for the AMP's weak sensitivity to evaluations in socially sensitive domains.
