We present the "open iat" and "open brief iat," two data-gathering tools that are hosted and freely available on Stanford's Political Communication Lab (PCL) website. These tools, written in PHP and jQuery, were created to facilitate the administration of Implicit Associations Tests (Greenwald and Banaji, 1995; Sriram and Greenwald, 2009) to survey respondents online at no cost and with minimal technical requirements. The open iat/biat serves as an alternative to high-priced iat services and makes it easy to create a study, track participants, and extract iat data. These tools integrate with Survey Monkey, Qualtrics and other survey software. They support text and image-based stimuli. Data processing is accomplished via an R script run on the server at the time of data extraction.
