From 2009 to present, the USA IAT was available on the Project Implicit Belgium website (https://implicit.harvard.edu/implicit/belgium/selectatest.jsp Click on “Landen” to try it yourself). The USA IAT includes one standard IAT (Good vs. Bad; Belgium vs. United States), sets of explicit measures on attitudes related to the countries (such as preference for United States and Belgium, 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 Dutch.
From 2009 to the end of 2017, there are 4,538 session IDs created for the USA IAT, and the overall completion rate is around 30.9%. There are 1,902 respondents who completed the standard IAT part of the task, which is 41.9% of the total respondents.
