**there was an error in some of the demographics variables for 2015 data where the values were missing or were not the correct values - if 2015 data was used between January 8, 2016 and September 23, 2016 please download the updated files**** From 2004 to present, the Asian American IAT was available on the Project Implicit demonstration website (https://implicit.harvard.edu/implicit/selectatest.html Click on “Asian IAT” to try it yourself). The Asian American IAT includes one standard IAT (Asian American vs. European American; American vs. Foreign), sets of explicit measures on attitude towards Asian American (such as Likert preference between Asian and European American), set of demographic questions (age, gender, race, etc.), and debriefing questions about how respondents thought about their IAT score after the task. From 2004 to the end of 2017, there are more than 886,443 session IDs created for Asian American IAT, and the overall completion rate is around 41.4%. There are 507,456 respondents who completed the standard IAT part of the task, which is 57.2% of the total respondents. Under this OSF project, you may download 1) Asian American IAT data sets with IAT score computed, self-report data labeled, and demographic information by year or for all years; 2) codebooks associated with each data set; and 3) experiment materials and description of procedure. The public data sets don't have participants' zip code/postcode to protect privacy. Please contact Project Implicit at admin@projectimplicit.net for any question or comment.
