Sure, take a look at the IAT sample located in the samples folder:
Code:
 
C:\DirectRT\Samples\5 other features\15 IAT-Race
Note that the sample has an "incorrect.txt" file located in the same folder as the input file. You can open that file in a text editor (like notepad.exe) and change the values that define the feedback--style ID, x position, y position, stimulus.
