• Download a copy of the TrackIt software.
• Mac/Windows: click the download file to open TrackIt.
• Linux: run the command java -jar TrackIt.jar
• You'll see a start-up screen with many options.
• Fill in the User Data section for your records only—this won't affect the actual experiment.
• Use the Trial Data section to specify experimental details (number and type of distracters, object speed, minimum trial length, etc).
• If you're using an eye tracker, you may wish to set the TrackIt frame rate to 60 or 120, depending on your hardware.
• Don't worry, we save all of this information in a file for you!
• When you're done, click Begin. You'll see a pop-up window asking you where to save all the data generated by the experiments.
• The experiment begins!
• The Spacebar moves you forward. Escape exits the program at any time.
• You'll see a grid with some shapes on it. Press spacebar to make them move.
• The shapes will eventually disappear; the participant indicates in which grid box the target stopped. Responses should be recorded via touchscreen.
• If you selected the Memory Check option, another screen will appear with a selection of shapes and the participant will pick out what he or she thinks was the target. Responses can be recorded via touchscreen or mouse click.
• A smiley face will appear on the screen regardless of response. Click.
• And it's on to the next trial!
• TrackIt records a lot of information, including the locations of all objects for the total duration of the trial and the precise locations and reaction times for participant clicks!
• The data is stored as a structured .csv file, which can be loaded and analyzed in, for example, Excel.
