Implicit Association Test

This is a demonstration of an IAT-procedure (Greenwald et al., 1998) to assess an individuals implicit attitudes toward a target concept programmed in javascript.



There are no claims whatsoever this is a valid test of implicit attitudes. Reaction time measurement over the internet is generally not easy, but not impossible (Reimers & Stewart, 2007) and javascript is (from a technical point of view) probably not the optimal technique to attempt that task. I wrote the script mostly for fun to experiment with the possibilities of javascript these days.


The script requires the javascript library jQuery licensed under the MIT and GPL.
