The FreeIAT won't do anything at all!

Most likely your system is not compatable with the FreeIAT. The FreeIAT was built using VB on Microsoft's .NET platform. While the software should prompt you if your system needs to download an update from Microsoft, try proactively downloading the latest verion of .NET from the Microsoft homepage.

The FreeIAT won't run once I click "Begin"

Most likely the FreeIAT cannot find the required configuration file 'config.txt'. Search your computer for the FreeIAT.exe program. In the same directory, there must be a 'config.txt' file to let the sytem know how to administer your IAT. Please see the FreeIAT homepage for specific instructions.

How do I run more than one IAT on the same computer?

Since the FreeIAT outputs scores using a single filename (e.g., ScoresOnly.txt), you'll need to create multiple folders to do this. The easiest way is to create a folder on your harddrive with the name of the IAT (e.g., RaceIAT). Next, locate the IAT program and associated files in the installation directory (e.g., C:/program files/FreeiAT/) and copy/paste the contents into the directory you just created (the RaceIAT folder). Repeat this process for a second IAT (e.g., GenderIAT). You'll also want to create new shortcuts from your desktop to each of the FreeIAT.exe programs and label them accordingly.

Where are the results and what do they mean?

FreeIAT stores results in two files. One containing only scored IAT results and the other containing all information about stimuli and responses. These files are described in detail at this webpage.

As far as interpreting IAT scores, the FreeIAT is intended for use by training Psychologists and other professions. Please do not use the FreeIAT if you do not understand what the test measures or how to interpret the output.

How do I merge results from many computers into a common file?

Just collect all of the scoring files from the different computers, open each one in a text editor and copy/paste them all into a new textfile.

Setting up your own IAT

Step 1:	Navigate to the directory where you keep the FreeIAT.exe file (the installation defaults to '/program files/FreeIAT').
Step 2:	If there is an existing 'Config.txt' file, rename it.
Now we are ready to set up a new IAT.
Step 3:	Start the FreeIAT program.
Step 4:	At the welcome screen, click on 'SetUp'.
Step 5:	Give your IAT a title and specify whether you will use images or not.
Step 6:	Label and specify the word stimuli for your first stimuli set (example: positive and negative words)
Step 7:	Label and specify the second stimuli set. This may be other word groupings or images. (example: presidential candidates)
Step 8:	Specify how many trials to administer per stage and how you want the output to appear.
