From 2006 to present, the USA IAT was available on the Project Implicit Germany website (https://implicit.harvard.edu/implicit/germany/selectatest.jsp Click on “Länder” to try it yourself). The USA IAT includes one standard IAT (Good vs. Bad; Germany vs. United States), sets of explicit measures on attitudes related to the countries (such as preference for United States and Germany etc.), set of demographic questions (age, gender, race, major, political identity, etc.), and debriefing questions about how respondents thought about their IAT score after the task. The study is in German.
From 2006 to the end of 2016, there are 42,285 session IDs created for the USA IAT, and the overall completion rate is around 50.9%. There are 24,964 respondents who completed the standard IAT part of the task, which is 59% of the total respondents.
