From 2008 to present, the Skin Tone IAT was available on the Project Implicit Australia website (https://implicit.harvard.edu/implicit/australia/selectatest.jsp Click on “Skin-tone” 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. From 2008 to the end of 2016, there are 31,254 session IDs created for Skin Tone IAT, and the overall completion rate is around 19.8%. There are 6,178 respondents who completed the standard IAT part of the task, which is 19.8% of the total respondents.
