From 2008 to present, the Skin Tone IAT was available on the Project Implicit Brazil website (https://implicit.harvard.edu/implicit/brazil/selectatest.jsp Click on “Cor da pele” to try it yourself). The Skin Tone IAT includes one standard IAT (Light Skin face vs. Dark Skin face; Good vs. Bad objects), sets of explicit measures on attitudes related to light skin/ dark skin (such as feeling thermometer for light skin/dark skin people 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 Portuguese. From 2008 to the end of 2017, there are 29,252 session IDs created for Skin Tone IAT, and the overall completion rate is around 19.4%. There are 7,853 respondents who completed the standard IAT part of the task, which is 26.9% of the total respondents.
