Running A Test With Stimulus Presentation Tool

1. Let the participant sit in front of the computer.
2. In the Welcome window, let the participant enter:
   • His/her name (optional; see step 7 in Define a test).
   • The values of the independent variables (optional, see step 6 in Define a test).
3. When ready, ask the participant to click Start.

   The Start button is available when the participant has entered the values of all required independent variables.

4. If you selected Perform gaze calibration when you defined the test, a message appears informing the participant that calibration will start when they click. The participant should look at the dots that appear on the screen and hover over them with their mouse.
5. After a couple of seconds the first Stimulus is displayed.
6. At the end of the test a message Thanks for Participating appears. The participant and analysis are added automatically in FaceReader.
